Abstract:
ABSTRACT The relationship between activity-based costing (ABC) and time-driven activity-based costing (TDABC) has not been systematically investigated. We compare the two systems analytically and via a numerical experiment. Our analytical comparison generates formulas that describe how each system maps resources to activities and finally to products. We demonstrate that ABC aggregates resource-to-activity information by resources (columns), while TDABC selects partitions of activity-by-resource information. Our numerical experiment shows that TDABC is more accurate than ABC when traceability of resources to activities is high and activity traceability to products is low, while ABC is more accurate when activities are more traceable to products, irrespective of the level of resource traceability to activities. Finally, we examine the impact of hybridizing an ABC (TDABC) system with TDABC (ABC). We find that adding one ABC element into a TDABC system usually improves accuracy. However, adding one TDABC element into an ABC system usually substantially degrades accuracy. Data Availability: The simulated datasets are available from the first author on request.

Abstract:
Purpose By designing a pilot time-driven activity-based costing (TDABC) model, this study aims to examine in depth the suitability and the complexity of TDABC in a manufacturing company. Design/methodology/approach To obtain a deeper understanding on the matters to analyse, this research adopts an interventionist approach. The host organisation is GP, a Portuguese company in the frozen food sector. Findings The authors’ experience allows them to assert that TDABC is suitable for a manufacturing company and it is able to deal with the variability of the industrial processes. Nonetheless, through a comparison with the models presented in the literature, TDABC appears to be more complex for manufacturing. The authors argue that this happens for two reasons. First, the two types of resources (human labour and machinery) used in production areas create a need to split tasks and to create two equations for each process, something that does not happen in service companies. Second, times are difficult to individualise for certain highly automated procedures, which could also give rise to some errors. Research limitations/implications The designed model is compared to other models presented in the literature. Practical implications This study shows a real example of TDABC in manufacturing and the procedural innovation of the time equations. Originality/value As the TDABC literature has been mostly focused on examples of service companies, the authors examine the technical suitability and the complexity of TDABC in manufacturing companies.

Abstract:
De ABC-paradox behelst het opmerkelijke verschijnsel dat er talrijke tekstboeken en conceptuele artikelen voorhanden zijn, waarin de (theoretische) voordelen van Activity-Based Costing (ABC) breed worden uitgemeten, maar dat tegelijk uit allerlei surveys blijkt dat ABC slechts door een relatief gering aantal bedrijven wordt toegepast. Dit artikel bespreekt mogelijke verklaringen van deze paradox door in te gaan op de essentie van ABC, onder welke omstandigheden succesvolle toepassingen mogelijk geacht werden en wat dan precies verbeterd zou worden in de bedrijfsvoering dankzij ABC. Time-Driven Activity-Based Costing (TDABC) is het antwoord van Kaplan en Anderson (2004; 2007) op de ABC-paradox. Het blijkt dat TDABC in essentie een tweetal nuances aanbrengt ten opzichte van ABC, de ene nuance heeft te maken met complexiteit, de andere met capaciteit. Dat deze beide problemen bestonden, was bekend in de diverse genres literatuur. De conclusie van dit artikel is, dat een reductie van complexiteit ten opzichte van ABC in de praktijk waarschijnlijk wel verwacht mag worden. De aanpassingen met betrekking tot capaciteit die TDABC voorstelt, waren weliswaar nodig, maar zijn niet voldoende.

Abstract:
AbstractThe activity-based costing (ABC) systems emerged as a management accounting innovation in the mid-1980s in response to dissatisfaction with traditional management accounting techniques and heightened international competition. Although ABC provides many advantages for managerial decision making, ABC tends to be outdated due to its limitations and is substituted by the time-driven activity-based costing (TDABC) systems. TDABC requires estimates of only two parameters: how much it costs per time unit of capacity to supply resources to activities and how much time it takes to perform each activity. TDABC allows incorporation of variation in the time demands made by different types of processes and consequently the representation of all possible combinations of activities that a process performs. This paper uses TDABC to calculate marketing costs and describes TDABC as a useful technique to reduce marketing resource costs and to support effective marketing decision making in various contexts such as marketing processes restructuring, marketing mix choices, customer profitability and price differentiation for customer classes.

Abstract:
By the 1980s, Traditional Cost Accounting (TCA) is no longer reflecting the current economic reality due to distorted information about the profitability of their orders, products, and customers. In addition, Activity-based Costing (ABC) is a costing method originally developed to overcome the shortcoming of TCA method in the era of rapidly increasing product complexity and diversification. However, it is not universally accepted because it ignores the potential for unused capacity which will be beneficial for forecasting. The objective of this work is to compare the advantages of ABC and Time-driven Activity-Based Costing (TDABC) by analyzing the features towards costing sustainment. The work begins by collecting data at electric electronic industry located at Pahang and the product selected is a magnetic inductor. ABC focuses on the costs inherent in the activity based products to produce, distribute or support the products concerned. TDABC uses time equation and capacity cost rate (CCR) to measure the unused capacity with respect to the time and cost. This work has successfully compares the methodology between ABC and TDABC in electronic industry. The item such as stages for cost allocation, determination of drivers, action taken for an additional activity, cost consideration for implementation, system building, system update, information given from each method, transparency, overestimation of cost, differentiation of service level, oversimplification of activities and capacity forecast and planning. It concludes that both have their strength according to the industry needs.

Abstract:
The cost of health is a recurrent topic that has generated much research, as it affects all of society. Both public and private agents need to know the real cost of treatments, services, and products for decision-making. This article aims to compare the use and research impact of two cost systems widely used in health: ABC and TDABC, which is an evolution of ABC. For doing so, a bibliometric review in Scopus and Medline was carried out encompassing the years 2009–2019. The results show a great increase in publications using TDABC, while publications on ABC stabilized. On the other hand, the TDABC articles presented higher research impacts in traditional and alternative metrics. Articles on TDABC are more frequently cited, published in better journals, and more visible in academic social networks. The findings suggest that scholars and practitioners should focus on TDABC rather than ABC for addressing cost in health for its simplicity, projection, and research opportunities.

Abstract:
Costs and their determination play a critical role in all manufacturing companies. The traditional costing system has received criticism resulting from the arbitrary allocation of indirect manufacturing costs. As an important initiative to address its weaknesses, new costing methods such as the Time-Driven Activity-Based Costing (TDABC) have emerged. Unfortunately, up to our knowledge, no investigations have been applied in analyzing assembly companies thoroughly nor considering all the processes necessary to obtain the final products. This article explores the TDABC application in the assembly industry through comparison with traditional volume-based costing by focusing on manual and semi-automatized production. Since the research is descriptive, a multiple-case study design was implemented in the assembly of televisions, motorcycles, and printed circuit boards. The developed methodology allowed determining the existence of factory overhead and direct labor cost variances between two different cost accounting systems, which also affected the unit cost of the products. Findings also highlight the benefits of TDABC application in the assembly industry, along with the shortcomings and future potential of research in this area.

Abstract:
Objective – This article provides an overview of how university libraries research and adapt new cost accounting models, such as “activity-based costing” (ABC) and “time-driven activity-based costing” (TDABC), focusing on the strengths and weaknesses of both methods to determine which of these two is suitable for application in university libraries. Methods – This paper reviews and summarizes the literature on cost accounting and costing practices of university libraries. A brief overview of the history of cost accounting, costing, and time and motion studies in libraries is also provided. The ABC and the TDABC method, designed as a revised and easier version of the ABC by Kaplan and Anderson (Kaplan & Anderson 2004) at the beginning of the 21st century, as well as the adoption and adaptation of these methods by university libraries are described, and their strengths and weaknesses, as well as their suitability for university libraries, are analyzed. Results – Cost accounting and costing studies in libraries have a long history, the first of these dating back to 1877. The development of cost accounting and time and motion studies can be seen as a natural evolution of techniques which were created to solve management problems. The ABC method is the best-known management accounting innovation of the last 20 years, and is already widely used in university libraries around the world. However, setting up an ABC system can be very costly, and the system needs to be regularly updated, which further increases its costs. The TDABC system can not only be implemented more quickly (and thus more cheaply), but also can be updated more easily than the traditional ABC, which makes the TDABC the more suitable method for university libraries. Conclusion – Both methods are suitable for university libraries. However, the ABC method can only be implemented in collaboration with an accounting department. The TDABC method can be tested and implemented by separate departments, and thus can contribute to the provision of better and more effective library services at lower costs. However, the involvement of experts in costing and accounting is recommended.

Abstract:
The research proposed a Time-Driven Activity-Based Costing (TDABC) model for cost and human capital analysis in a small startup in Indonesia. TDABC discussed and illustrated the integration of capabilities into cost and performance in startups. The researchers applied a qualitative simulation method. The data were taken from actual regulatory data of wage and salary from the local government of Jakarta. The other data were simulated data based on a software development process for a small startup. The result indicates that the TDABC can assist the company to trace its performance and costs. Additional factors in implementing the costing system are provided for further research and practical considerations in adopting the costing system.

Abstract:
Object To date, health care providers have devoted significant efforts to improve performance regarding patient safety and quality of care. To address the lagging involvement of health care providers in the cost component of the value equation, UCLA Health piloted the implementation of time-driven activity-based costing (TDABC). Here, the authors describe the implementation experiment, share lessons learned across the care continuum, and report how TDABC has actively engaged health care providers in costing activities and care redesign. Methods After the selection of pilots in neurosurgery and urology and the creation of the TDABC team, multidisciplinary process mapping sessions, capacity-cost calculations, and model integration were coordinated and offered to engage care providers at each phase. Results Reviewing the maps for the entire episode of care, varying types of personnel involved in the delivery of care were noted: 63 for the neurosurgery pilot and 61 for the urology pilot. The average cost capacities for care coordinators, nurses, residents, and faculty were $0.70 (range $0.63–$0.75), $1.55 (range $1.28–$2.04), $0.58 (range $0.56–$0.62), and $3.54 (range $2.29–$4.52), across both pilots. After calculating the costs for material, equipment, and space, the TDABC model enabled the linking of a specific step of the care cycle (who performed the step and its duration) and its associated costs. Both pilots identified important opportunities to redesign care delivery in a costconscious fashion. Conclusions The experimentation and implementation phases of the TDABC model have succeeded in engaging health care providers in process assessment and costing activities. The TDABC model proved to be a catalyzing agent for cost-conscious care redesign.

Abstract:
Purpose – The purpose of this paper is to discuss the potentialities of innovative accounting tools in supporting “transparency” and “resource allocation” in public hospitals, by describing the implementation of a pilot project of time-driven activity-based costing (TDABC). Design/methodology/approach – An interventionist research (IR) approach has been adopted: two medical doctors, three financial controllers and three researchers were involved. Collection of data used to implement the accounting model is based on hospital databases and interviews. Findings – The information produced may allow a higher coherence between resources and activities. TDABC may enhance transparency and support decisions toward a better organization of work and an informed allocation of resources. Research limitations/implications – Further studies are required to analyze decisions following the implementation of the TDABC model. Originality/value – The accounting literature lacks case studies describing the application of TDABC in hospital settings, despite its good informative potentialities and the limited investment required to introduce TDABC. Moreover, the use of the IR approach and the involvement of medical doctors may help to get coherence between accounting data and clinical work and may support the further diffusion and development of this costing model in hospitals.

The purpose of this paper is to calculate branding consultant cost using Time-Driven Activity-Based Costing (TDABC). TDABC calculate cost based on activity that is controlled by time. The method that is used in this research is a case study in Unixon, a small business that works in the field of branding, using data from 2016. Interviews were conducted. The cost and activity database was analyzed. The results of this research show that TDABC can be applied in this Company because it qualified the requirements; diversity in product and different time consumption ratio for each product. TDABC provided more accurate cost information by calculating all costs; cost to make and cost to sell. Implementation of TDABC also show time capacity utilization by comparing actual labor hours and work hours that is controlled by government regulation. By understanding this condition, the owner is able to evaluate the amount of job that is done, time consumption, and employee who is involved. To implement TDABC, the Company must consider each steps needed from identifying activity, assign cost to activity, calculate tariff per activity, to calculate cost of product.

Abstract:
Objective The aim of the present study was to explore the differences between resource consumption accounting (RCA) and time-driven activity-based costing (TDABC) systems in determining the costs of services of a healthcare setting. Methods A case study was conducted to calculate the unit costs of open and laparoscopic gall bladder surgeries using TDABC and RCA. Results The RCA system assigns a higher cost both to open and laparoscopic gall bladder surgeries than TDABC. The total cost of unused capacity under the TDABC system is also double that in RCA. Conclusion Unlike TDABC, RCA calculates lower costs for unused capacities but higher costs for products or services in a healthcare setting in which fixed costs make up a high proportion of total costs. What is known about the topic? TDABC is a revision of the activity-based costing (ABC) system. RCA is also a new costing system that includes both the theoretical advantages of ABC and the practical advantages of German costing. However, little is known about the differences arising from application of TDABC and RCA. What does this paper add? There is no study comparing both TDABC and RCA in a single case study based on a real-world healthcare setting. Thus, the present study fills this gap in the literature and it is unique in the sense that it is the first case study comparing TDABC and RCA for open and laparoscopic gall bladder surgeries in a healthcare setting. What are the implications for practitioners? This study provides several interesting results for managers and cost accounting researchers. Thus, it will contribute to the spread of RCA studies in healthcare settings. It will also help the implementers of TDABC to revise data concerning the cost of unused capacity. In addition, by separating costs into fixed and variable, the paper will help managers to create a blended (combined) system that can improve both short- and long-term decisions.

Abstract:
This research proposes a guide to implementation of time- driven activity -based costing (TDABC) in Saudi Electronic University (SEU) as an alternative to the traditional costing systems. It is worth mentioning that the cost accounting system should support mission and vision of the university by detecting any idle capacity and providing relevant information for rational decision-making as well as improving the quality of services provided to students and finally managing SEU’s resources efficiently and effectively. According to Saudi’s vision 2030, public universities in Saudi Arabia should act on both of revenue side and cost side. In the current costing system of SEU, there are no cost pools at colleges’ level, at academic departments’ level, at courses’ level, as well as at students’ level. Rather cost pools found at university’ level only. Therefore, the current costing system provides neither information on unit cost per student at any academic program nor information on the unused capacity at any resource centers. Despite the fact that TDABC theoretically overcomes the criticism to both traditional costing system that uses direct labor or machine hours as a cost driver and the traditional activity- based costing (ABC that uses many transactions cost drivers to allocate overhead costs to cost objects. The implementation of TDABC is still challenging particularly in universities by using the time as the primary cost driver for allocating resource costs to final cost objects in academic programs especially the human labor is considered the main resource in universities. The proposed guide to implementation TDABC provided SEU’s management information, including but not limited to, the average actual unit cost per student in each academic program either per semester, or per year, comparing actual fees students paid in each academic program to the actual average unit cost in each academic program to determine whether SEU covers all costs. In addition, comparing the average unit cost per student among all academic programs and investigating reasons of variations. The guide helps management determine the unused capacity in each resource center as well as preparing budgets of all resource centers accurately based on the actual used capacity.

Abstract:
Costing is an important issue in a competitive world. Many companies had adopted TDABC for better cost visibility. Assembly is very common activity in the small scale industries (SSI). In a SSI, many operations like riveting, drilling, fastening, loosening and tightening, hammering, labeling, aligning, etc. are carried out at the time of assembly. Also the sequence and the time of the operating vary for each product. Therefore, it is difficult to estimate the cost of complex assembly. This paper proposed a time driven activity based costing (TDABC) model to estimate the cost of assembly for SSI. TDABC uses time equations to estimate the time required for an activity. A new approach to develop the time equation using maynard operation sequence technique (MOST) is presented. This paper also presents the modification in the time equation to handle the complexity of the activity. The application of the model is presented with the case study. The cost analysis helps to identify the opportunities for low cost assembly solution.

IntroductionOsteoarthritis of the knee has been identified as the most common disability in Pakistan. Total knee replacement (TKR) surgery is the curative treatment for advanced osteoarthritis of the knee; however, cost remains one of the barriers to effective and timely service delivery.ObjectiveWe conducted a time-driven activity-based costing (TDABC) analysis of TKR to identify major cost drivers and areas for process improvement.Methods and analysisWe performed a prospective TDABC analysis of patients who underwent bilateral TKR at The Indus Hospital (TIH) during a 14-month period from October 2015 to December 2016. Detailed process maps were developed for each phase of the care cycle. Time durations and costs were allocated to each resource utilised and aggregated across the care cycle, including personnel, direct and indirect costs.ResultsWe identified seven care phases for a complete TKR care cycle and created their detailed process maps. Major time contributors were ward stay and discharge (20 160 min), TKR surgery (563 min) and surgical admission (333 min). Overall, 92.10% of time is spent during the ward stay and discharge phase of care. Patients remain hospitalised for an average of 14 days postoperatively. Overall institutional cost of a TKR at TIH was US$4360.51 (Pakistani rupees 456 981.17) per bilateral TKR surgery. The overall primary cost drivers for the full bundle of care were consumables used during TKR surgery itself, consumables utilised in the wards and personnel costs contributing 57.64%, 27.45% and 12.03% of total costs, respectively.ConclusionUtilising TDABC allowed us to obtain a granular analysis of time and cost that was subsequently used to inform quality process improvement initiatives. In low-resource settings, such as Pakistan, TDABC has the potential to be a useful tool to guide resource allocation and process improvement.

Abstract:
PURPOSE: As health care costs rise, continuous quality improvement and increased efficiency are crucial to reduce costs while providing high-quality care. Time-driven activity-based costing (TDABC) can help identify inefficiencies in processes of cancer care delivery. This study measured the process performance of Port-a-Cath placement in an outpatient cancer surgery center by using TDABC to evaluate patient care process. METHODS: Data were collected from the Anesthesia Information Management System database and OneConnect electronic health record (EHR) for Port-a-Cath cases performed throughout four phases: preintervention (phase I), postintervention, stabilization, and pre–new EHR (phases II and III), and post–new EHR (phase IV). TDABC methods were used to map and calculate process times and costs. RESULTS: Comparing all phases, as measured with TDABC methodology, a decrease in post-anesthesia care unit (PACU) length of stay (LOS) was identified (83 minutes v 67 minutes; P < .05). The decrease in PACU LOS correlated with increased efficiency and decreasing process costs and PACU nurse resource use by fast tracking patients for Port-a-Cath placement. Port-a-Cath placement success and the functionality of ports remained the same as patient experience improved. CONCLUSION: TDABC can be used to evaluate processes of care delivery to patients with cancer and to quantify changes made to those processes. Patients’ PACU LOS decreased on the basis of the 2013 Port-a-Cath process improvement initiative and after implementation of a new EHR, over the course of 3 years, as quantified by TDABC. TDABC use can lead to improved efficiencies in patient care delivery that are quantifiable and measurable.

Abstract:
79 Background: Since 2010 The University of Texas MD Anderson Cancer Center (UTMDACC) has been using Time Driven Activity Based Costing (TDABC) to assist in tracking and quantifying changes made to clinical processes to improve efficiency of patient care delivery. Radiation Oncology (RO) providers have recently utilized this method to assist in the growing clinical patient volumes and increasing enrollment in clinical trials. UTMDACC contains disease specific multi-disciplinary centers with separate clinics for different disciplines. Resources are limited which can affect clinical providers’ ability to meet the needs of increasing patient volumes. Implementing efficient clinic work flow models will allow clinicians to provide excellent quality of clinical care even with limited resources. Methods: Standard disease-site specific note templates were created and implemented throughout the entire RO department. Additionally, standardized roles for medical assistants, residents, physician assistants (PAs), attending physicians and nurses were implemented to minimize duplication of responsibilities. Using TDABC methodology, process maps for pre and post implementation pathways were created to illustrate areas of change and possible benefit. Results: Process maps were compared for new consult and follow up and on treatment patient visits. Process times for these patient care visits were compared pre- and post-implementation of templates and clinical roles. Time savings of 110, 18 and 34 minutes were observed for consult visits, follow up visits and on-treatment visits when comparing current to baseline process maps. Conclusions: Standardization of note templates and roles for all members of the care team has led to improvements in process flow and efficiency in the RO clinic setting. Our findings suggest that further implementation of TDABC methodology by having all providers work at the top of their license could can improve clinical efficiency and patient care. Further metrics with a larger sample size is recommended to validate our results. [Table: see text]

Abstract:
Geriatric hip fractures are a common and costly injury. They are expected to surge in incidence and economic burden as the population ages. With an increasing financial strain on the healthcare system, payors and providers are looking toward alternative, value-based models to contain costs. Value in healthcare is the ratio of outcomes achieved over costs incurred, and can be improved by reducing cost while maintaining or improving outcomes, or by improving outcomes while maintaining or reducing costs. Therefore, an understanding of cost, the denominator of the value equation, is essential to value-based healthcare. Because traditional hospital accounting methods do not link costs to conditions, there has been little research to date on the costs of treating geriatric hip fractures over the entire cycle of care. The aim of this article is to summarize existing costing methodologies, and in particular, to review the strengths and limitations of Time-Driven Activity-Based Costing (TDABC) in orthopaedic trauma, especially as it pertains to the needs and challenges unique to hip fracture care. TDABC determines costs at the patient-level over the entire care cycle, allowing for population variability, while simultaneously identifying cost drivers that might inform risk-stratification for future alternative payment models. Through process mapping, TDABC also reveals areas of variation or inefficiency that can be targeted for optimization, and empowers physicians by focusing on costs in the control of the provider. Although barriers remain, TDABC is well-positioned to provide transparent costing and targets to improve the value of hip fracture care

Abstract:
Abstract Costing system is an essential part of a company. Determining the accurate cost of a product or service is extremely important for the profitability and performance of a company. Over the years, different approaches and models have been developed to estimate the cost of the product manufactured. However, their models were found to be inadequate in the correct value of the product cost. In the last decade, activity-based costing (ABC) has been successfully adopted by many companies worldwide. Nonetheless, because of its high maintenance and setup cost, it has been abandoned and a new time-driven activity-based costing (TDABC) model has been developed. Though adopted by many large scale-manufacturing industries, TDABC has not been implemented in small scale manufacturing companies due to unavailability of resources and also ignorance about its implementation. This paper presents a model for the application of TDABC in the small scale manufacturing industry. The model is implemented in a furniture manufacturing company for the estimation of product cost. The cost obtained from the TDABC is compared with the traditional costing system and established the accuracy of TDABC over the traditional costing system. Along with the case study, this paper also discusses the different data results obtained from TDABC and its utility for the managers and the decision makers.

Abstract:
Background: Depending on available resources, competencies, and pedagogic preference, initiation of insulin pump therapy can be performed on either an individual or a group basis. Here we compared the two models with respect to resources used. Methods: Time-driven activity-based costing (TDABC) was used to compare initiating insulin pump treatment in groups (GT) to individual treatment (IT). Activities and cost drivers were identified, timed, or estimated at location. Medical quality and patient satisfaction were assumed to be noninferior and were not measured. Results: GT was about 30% less time-consuming and 17% less cost driving per patient and activity compared to IT. As a batch driver (16 patients in one group) GT produced an upward jigsaw-shaped accumulative cost curve compared to the incremental increase incurred by IT. Taking the alternate cost for those not attending into account, and realizing the cost of opportunity gained, suggested that GT was cost neutral already when 5 of 16 patients attended, and that a second group could be initiated at no additional cost as the attendance rate reached 15:1. Conclusions: We found TDABC to be effective in comparing treatment alternatives, improving cost control and decision making. Everything else being equal, if the setup is available, our data suggest that initiating insulin pump treatment in groups is far more cost effective than on an individual basis and that TDABC may be used to find the balance point.

Abstract:
28 Background: Historically, hospital costs are based on a cost-to-charge ratio. The current cost system determines when a charge is filed and a bill is created, which can be days following the patient visit. This time lag between the patient visit and the billed charges can be problematic. In preparation for episode-based payments, it is essential to know the true cost of care at the time of delivery. To accomplish this goal, the University of Texas MD Anderson Cancer Center (MDACC) leveraged existing time-driven activity-based costing (TDABC) process maps to track the true costs of the patient care cycle. Methods: The first steps were to understand the patient care cycle through process mapping. Next, data sources were identified to capture patient volumes. Process maps were adjusted to capture the data sources and provide a more accurate cost. Trigger logic models were created to link data sources and the TDABC process maps to the true cost for each patient appointment. Lastly, we developed a SAS software program to compute the real-time TDABC costs for 50 patients in the Head & Neck Center. Results: Our existing data sources capture information relevant to TDABC on a regular basis. Patient appointment data provided the patient visit, and billing and time data provided approximations of the amount of time spent in the encounter and the number of resources involved in the patient visit. Out of 219 process maps, 148 (70%) were matched to existing patient appointment and charge data using the trigger logic. This allowed us to track 4,980 patient appointments for 50 patients in fifteen minutes. Conclusions: As data are collected throughout the institution, it is realized that multiple data sources are needed to reconcile the patient’s experience and to match the TDABC process maps to existing data sources. Since our data sources are updated daily and are based on a patient’s date of service, we can capture our costs of delivering care close to real-time. This process is continually refined as additional data sources are made available and as process maps are developed in other parts of MDACC.

Abstract:
The purpose of this research is to design a production company fitted full product cost calculation model following analysis of Activity Based Costing (ABC), its modifications and LEAN accounting system principles. The study is based on analysis and comparison in ABC, Time Driven Activity Based Costing (TDABC), Service-Based Costing (S-BC), Duration Based Costing (DBC) and LEAN accounting. The designed innovative full product cost calculation model integrates the following management system elements: LEAN value streams, ABC activities, TDABC time driver, S-BC customer rating, and DBC production duration factor, and has been adapted to a company producing large and complex unique articles. Applicability analysis of the model has involved data systematization, grouping, collection of additional data under the interview method, data interpretation, summarisation, logical conclusion making. Applicability of this model and more efficient control of the pricing decisions at the company, ensuring its greater competitive ability, have been justified by financial calculations. In formation of the full cost calculation model, both the quantitative and qualitative research elements were used: analysis of the modern cost accounting systems was performed; applicability, implications and limitations of the designed model were tested using actual data of the selected industrial company.

In a service company, the cost of services is sometimes not calculated accurately by the owner or management. This is due to the difficulty of calculating the cost as indirect costs occur together with the activities of the services performed. One of the methods of calculating the cost of services is the Time-driven activity-based costing (TDABC) method. This study applied the method to calculate the cost of services of Kurnia Motor Workshop, a company that offers antique car restoration services. The analysis showed that the TDABC method was a suitable method to calculate the cost of services accurately in Kurnia Motor Workshop.

Abstract:
Abstract Purpose In value-based health care delivery, radiation oncologists need to compare empiric costs of care delivery with advanced technologies, such as intensity-modulated proton therapy (IMPT) and intensity-modulated radiation therapy (IMRT). We used time-driven activity-based costing (TDABC) to compare the costs of delivering IMPT and IMRT in a case-matched pilot study of patients with newly diagnosed oropharyngeal (OPC) cancer. Materials and Methods We used clinicopathologic factors to match 25 patients with OPC who received IMPT in 2011-12 with 25 patients with OPC treated with IMRT in 2000-09. Process maps were created for each multidisciplinary clinical activity (including chemotherapy and ancillary services) from initial consultation through 1 month of follow-up. Resource costs and times were determined for each activity. Each patient-specific activity was linked with a process map and TDABC over the full cycle of care. All calculated costs were normalized to the lowest-cost IMRT patient. Results TDABC costs for IMRT were 1.00 to 3.33 times that of the lowest-cost IMRT patient (mean ± SD: 1.65 ± 0.56), while costs for IMPT were 1.88 to 4.32 times that of the lowest-cost IMRT patient (2.58 ± 0.39) (P &lt; .05). Although single-fraction costs were 2.79 times higher for IMPT than for IMRT (owing to higher equipment costs), average full cycle cost of IMPT was 1.53 times higher than IMRT, suggesting that the initial cost increase is partly mitigated by reductions in costs for other, non-RT supportive health care services. Conclusions In this matched sample, although IMPT was on average more costly than IMRT primarily owing to higher equipment costs, a subset of IMRT patients had similar costs to IMPT patients, owing to greater use of supportive care resources. Multidimensional patient outcomes and TDABC provide vital methodology for defining the value of radiation therapy modalities.

9 Background: Value-based and quality health care delivery has become an important focus for many health care systems. The purpose of this study was to assess the cost differences in treating low and intermediate risk endometrial cancer using time-derived activity based costing (TDABC) in a large regional cancer network model. Methods: Process mapping and TDABC was performed in treating endometrial cancer patients at a large tertiary cancer center (main) with a regional cancer network program. Clinical visits and adjuvant therapy including high-dose rate vaginal cuff brachytherapy (VBT) and pelvic radiation (PRT) were performed in ambulatory treatment centers at each location. Surgery for endometrial cancer was performed at the main cancer center. Costs for each process point was determine by cost-capacity rates, and compared by treatment center location. Results: TDABC costing determined a 28.3% cost difference in ambulatory clinic visits for endometrial cancer patients, favoring treatment at the regional network location. There was no cost difference in surgery for endometrial cancer patients since all procedures were performed at main. Delivering adjuvant VBT was 44.2% more in the ambulatory regional center compared to main, primarily due to the radiation quality assurance checks at the regional site. TDABC costing determined a 39.8% cost difference in delivering PRT for intermediate risk endometrial cancer patients, favoring treatment at the regional network location. Overall, there was a 13.2% cost savings, favoring treatment at the regional cancer network location. Conclusions: Delivering care for low and intermediate risk endometrial cancer in a regional network model may represent a cost effective health care delivery method. Quality assurance checks at the regional locations are required for quality treatment delivery, however, may represent an area for cost effective process improvements or need to stratify treatment location based on complexity.

Abstract:
Purpose The purpose of this paper is to provide a case study about the capacity utilization analysis in a small-sized manufacturing company through the application of time-driven activity-based costing (TDABC). After a brief overview of development of the TDABC system, a detailed application of TDABC and capacity utilization analysis in a bakery is given. Design/methodology/approach This paper is based on a case study about the application of TDABC in a small-sized Greek manufacturing firm. In the case study, time equations were developed for the supporting, operating and manufacturing departments and product costs determined based on the model. Capacity utilization analysis made through the application of TDABC system. Findings The study shows that TDABC is more applicable in small-sized manufacturing companies because of their labor-intensive nature. In contrast to previous studies, authors argue that even in small firms simple excel sheets are not enough to capture the complexity of the time equations and business intelligence software and programming coding is required. Research limitations/implications Although the fundamental structure of TDABC is the same for all companies there is no strict form of application. Practical implications The practical implication of this paper is that each firm has unique characteristics that need to be reflected in the application of the TDABC model. Originality/value This paper contributes by providing insights into cost accounting in SMEs. More specifically, this paper contributes to the TDABC literature regarding the application of the system in small and medium sized manufacturing firms.

Abstract:
The paper explored the impact of applying the time driven activity-based costing-TDABC- model (independent variables) on improving the efficiency of performance (dependent variables) in Jordanian industrial corporations. Based on a questionnaire form data from a sample of 73 participants at different managerial positions, from 30 industrial corporations listed in Amman stock exchange (ASE), were gathered and processed using the statistical package of social sciences. The main results showed that there are significant impacts of applying TDABC on improving the efficiency of performance in Jordanian industrial corporations. The main conclusion indicated that TDABC has the ability to benefit from technological developments on the basis of the activities’ charts and reflected on pricing decision making processes in industrial corporations. The research also concluded that senior management and cost accountants of the sample studied did not desire in the short run to change the current cost accounting system due to the additional costs of using the new cost accounting system. The study recommended the application of TDABC in corporations where their operations relied on TDABC’s constituents as proved its impact on reducing costs of products and increasing corporations profitability.

Abstract:
Malaysia currently accounts for 28% of world palm oil production and 33% of world exports. Being one of the biggest producers and exporters of palm oil and palm oil products, Malaysia has an important role to play in fulfilling the growing global need for oils and fats sustainably. In recent times, few problems have actually happened in this plantation which are difficult to establish a time equation for analyzing the variation of activities, the rate establishment is unsuitable to display the connection between resources supplied and the practical capacity and the manager does not have a method for monitoring capacity usage and unused capacity. The aim of this work is to develop the time equation of mature and immature area at ramp for a better accuracy. Time driven activity-based costing (TDABC) is implemented because the time is successfully measured, the idle capacity is correctly determined and the capacity used and the unused capacity are differently listed. This work considers a data in 2017 to develop the solution. This work found that in the mature area from the available capacity utilization, ramp has high unused capacity with 67492.80 min which means the resources should be forecast properly in future. Meanwhile in the immature area, ramp has closest value to the practical capacity with 6667.20 min and RM5667.12 which indicates the company properly utilizes their resources. Therefore, TDABC provides more comprehensive understanding of practical resources and its associated costs while measuring processes and encouraging quality improvement.

Abstract:
196 Background: The aim of the project was to use anesthesia providers in a cancer center to lead process improvements using time-driven activity-based costing (TDABC), a system of measuring process and capacity costs. Methods: The process improvement objectives were centered on eliminating unnecessary patient care processes and improving patient flow. Teams were tasked with planning, process mapping, improving processes, and measuring costs. Projects were done in four anesthesia sites: ambulatory surgery, bone marrow aspiration, pediatric CT and XRT, and cardiopulmonary areas. Results: Process mapping identified areas for improvement and costs before and after the improvement. The Table highlights four project areas’ average total cost and time savings per patient using TDABC methodology. Conclusions: TDABC is a costing methodology that measures the costs of care utilizing process maps. Anesthesia providers had front-line insight in improving process flow and found the process mapping useful to improve processes and measure the cost savings of the improvement. In each area there was improvement or no adverse effect on patient outcomes. This project demonstrates that TDABC illustrates inefficiencies and provides a method to evaluate the cost savings of process improvements. As cancer care reimbursement evolves, the ability to control costs while providing value-based care is essential. [Table: see text]

Abstract:
Palm oil is one of the world's most traded farming commodities. The Malaysian palm oil industry is without a doubt to the nation's pride. However, there are few problems currently happen in this plantation which are no establishment of time equation to interpret deviation of activities, the rate establishment did not properly illustrate the correlation between supplied resources and practical capacity, and the manager did not have a tool to monitor the unused capacity. The aim of this work is to develop a new costing structure for a better accuracy specifically at nursery. Time-driven activity-based costing (TDABC) was applied because it can effectively measure the time efficiency, accurately identifies the idle capacity and separately lists the used and unused capacity. It also provides more comprehensive understanding of practical resources and its associated costs while measuring processes and encouraging quality improvement. The plantation located at Pahang which has three main divisions and this work was focussing on nursery only. This work found that a precise process mapping for nursery was developed to understand their specific sequence which contributes to time equations. Subsequently, the total used capacity and capacity cost rate (CCR) for pre-nursery was successfully developed with 98220 minutes and 0.168 RM/minute respectively. Eventually, the manager can observe that actually the unused capacity was 37515.31 min which can be used to systematically develop the capacity planning on the pre-nursery.

Abstract:
Introduction:Extracorporeal circulatory membrane oxygenation (ECMO) is a technology that allows recovery of adults in cardiorespiratory failure with encouraging results, but is not available in the Brazilian universal public health system (SUS) due to high implementation costs. Time-driven activity based costing (TDABC) is applied to measure processes in an economic perspective by identifying opportunities to make processes more efficient through the reduction of resources used in each activity. The literature has explored the use of TDABC to measure costs related with clinical procedures and technologies in microcosting studies, identifying opportunities to improve the process by making it more efficient. This research measures the real costs to implement ECMO in Brazil to compare with the current public reimbursement system.Methods:This study applied TDABC using data from 6 patients to measure costs of ECMO intervention considering the public perspective in Brazil. In sequence, standard price payed by SUS was used to estimate the current reimbursement amount received by the hospital for ECMO procedure. Cost variable analysis was conducted to understand when and how patients receiving ECMO are using hospital resources. Cost data were collected from an academic public hospital using an average of 18 months (2016–2017) for the department costs.Results:The real average cost was USD 128,923. Most significant resource costs was medical staff, particularly for the three survivor patients, and the ECMO equipment presented the second highest cost. ECMO activities were separated into: before implantation of ECMO, period using ECMO, intensive care post-ECMO and rehabilitation, being the period where ECMO is the most expensive, particularly in nurse and physician costs. The SUS average was USD 31,437, which shows a difference of USD 97,485 between the real ECMO cost and the public reimbursement in Brazil.Conclusions:A critical element of the propagation of ECMO in Brazil and its reimbursement by public health system is the high cost and out-of-date standard payments by the Ministry of Health. Effort to implement a trustworthy method to guide decisions of SUS for the adoption and financing new technologies is essential to contribute to the optimization of public health policies in a country with a universal health system and limited resources dedicated to health sectors.

Abstract:
Objectives: Annually, an estimated 250,000 anterior cruciate ligament (ACL) reconstructions are performed. Operative management of ACL injuries has increased 22% between 2002 and 2014. With national healthcare expenditures rising at unsustainable rates, an improved understanding of healthcare costs is essential to identifying avenues of inefficiency and implement innovative solutions. This study is purposed to utilize time-driven activity-based costing (TDABC) to estimate the costs for the two-year care episode in the surgical reconstruction of ACL tears. Provided its high incidence, the operative reconstruction of ACL injuries serves as a prime setting for this study. Methods: This study follows 611 patients that underwent an ACL reconstruction for an acute ACL tear between 2009-2016 within a single outpatient orthopaedic surgery center (Figure 1). Patient demographics were collected via the electronic medical record (EMR) (Table 1). The total cost-of-care was determined using time-driven activity-based-costing (TDABC). This formula derives the cost of care as a function of the time spent for each activity and personnel cost contributions for all involved. This process was performed at all phases: surgical intervention, all clinical follow-ups, and physical therapy (PT) sessions. Results: A total of 611 patients were included for this investigation. The patient sample was primarily female (n=355, 58.1%) with an average age of 28.9 + 12.9 [27.9, 30.0], and average BMI of 25.5 + 4.5 [25.2, 25.9]. The majority of the patients identified with an Anesthesiologist Society of America (ASA) score of 1 (n=505, 83.9%). The average operative time was 107.1 + 31.5 minutes [104.6, 109.6]. The average TDABC cost-of-care was derived at $3364.95 + $958.99 [$3288.75, $3441.14]. Surgical costs occupied the greatest proportion of the overall cost-of-care, $1836.11 (53.2%), followed by costs relating to surgical implants, $911.61 (27.1%), physical therapy appointments, $342.00 (10.2%), and clinical follow-up appointments, $318.77 (9.5%) (Figure 1). A total of 459 (75.1%) patients were treated with an autograft, averaging a total cost-of-care of $2882.19, with the 90th percentile costing $3427.23 and 10th percentile costing $2343.08, reporting a 16.0% variability in costing. Of the 152 (24.9%) allografts, the average cost of care was $4884.10, with the 90th percentile costing $5321.50 and 10th percentile costing $4411.25, reporting a 9.0% variability. Hamstring autografts reported a significantly higher cost-of-care when compared to bone-patellar-bone (BTB) autografts (Hamstring: $3120.10 vs BTB: $2718.60; p<0.01). Conclusion: Given the increasing frequency of ACL procedures performed, an improved understanding of its costing components is critical for implementing change and strategizing solutions for increasing healthcare costs. Operative costs drive the total cost of care with implants, graft choice, and surgical resources constituting almost 80% for the two-year cost episode. With the growing focus of healthcare transitioning towards value-based healthcare delivery and cost reduction, identifying areas of costing inefficiency in surgical decision-making and implant-choice provides an avenue to reduce costs.

Abstract:
25 Background: Poor costing systems and measurement have led to cross-subsidies and cost-shifting in health care. A large academic cancer center has adopted Robert Kaplan’s bottom-up cost accounting methodology called time-driven, activity-based costing (TDABC). TDABC in health care has been proven to be an effective cost accounting tool to measure and improve care delivery by standardizing and creating transparency around patient care processes. The project aims to process map and identify event triggers associated with each process map, use a software applications to compute the costs and resource capacities. Methods: Information technology and financial subject-matter experts integrated clinical, resource, and financial data from the institution’s enterprise information warehouse, general ledger, resource and asset management systems into the software application. Clinical business managers, nurse managers and other clinical content experts helped identify patient-level care processes. Results: The institution deployed a project team to integrate data from the institution’s enterprise information warehouse and aid in the process mapping across three multidisciplinary care centers. The team was able to successfully cost both direct and overhead costs associated with 69 head and neck, 18 endocrine, and 15-20 proton therapy patient-level processes over 7 different business department within 7 months. The resource capacity analysis was the most difficult to analyze due of the lack of transparency around resource’s clinical, administrative, and research responsibilities. Dashboards are currently being developed to help assess changes in patient care processes, cost or resource utilization. Conclusions: This methodology can be used across all health care organizations in all countries to analyze the true cost of care delivery.

Abstract:
Nowadays, demand for magnetic components are increasing from customer to support technological needs. It is important for the producer to incorporate an accurate cost estimation to decide the best price to gain better profits. However, actual costing structure is ignored the potential of time equation and capacity cost rate to measure the unused capacity from the resources allotment. The objective of this work is to determine the unused capacity in term of duration and cost in the manufacturing of electronic component using time-driven activity-based costing (TDABC). The method was developed using seven stages which are resources group identification, estimate cost of resources supplied, practical capacity estimation, capacity cost rates calculation, time equation development, determine time estimates for each sub-activity and estimate capacity cost required. As a result, in sub-activity-1, the unused time was 246,156.29 minutes which needs to be re-examined so that maximum time for productivity can be achieved and the unused capacity of cost was MYR 623,804.93 which conveys the message of wastage at the workstation. In sub-activity-3, the amount of unused time and cost was -596,400 minutes and MYR -7,006,252.43 respectively. The negative value demonstrated that the operators are overworked than normal time allocation. In sub-activity 9, the amount of unused time was -596,400 minutes and MYR -7,006,252.43 for unused cost probably the job scopes were taking more time than it should to be completed. Therefore, by applying the TDABC method, the capacity utilization and time efficiency can be clearly viewed.
