Software product line has been a key area of concern in software industry due to its advantage on the productivity and quality of software products. At same time, both software organizations and the academic community are aware that the software measurement is necessary in software product line. However, there are many problems: what is difference in software product line measurement, how about their measurement process in the end, etc. It addresses this problem by creating a specialized Software Product Line Measurement Process Capability Maturity Model (SPLMP-CMM). SPLMP-CMM including five maturity levels: initial, tentatively, defined, compesive and optimized. The model focus on the basic practice areas which should be implementing of every level, it helps the originations to assess their measurement process and provides guidance for them to a higher maturity level.

Prozessfähigkeitsuntersuchungen vergleichen die Verteilung eines Fertigungsprozesses mit den definierten Toleranzen eines Qualitätsmerkmals. Allerdings kann die Messunsicherheit die beobachtete Qualität des Fertigungsprozesses dabei erheblich beeinflussen. Um die Untersuchung von Prozessfähigkeiten in der diskreten Fertigung zu verbessern, wird die „Entfaltung“ als allgemeine Methode zur mathematischen Korrektur von systematischen und zufälligen Messabweichungen vorgeschlagen.   Process capability assessments compare the distribution of a manufacturing process to the defined tolerances of the manufactured part. However, measurement uncertainty can greatly distort the observed performance of manufacturing processes. To reduce the impact of measurement uncertainty on the assessment of a manufacturing process distribution, deconvolution is proposed as a general method to mathematically correct both systematic and random measurement deviations.

This paper presents the capability of an ultrasonic system for the in-process surface roughness measurement of machined parts. The system uses a focused ultrasonic transducer to measure the reflected amplitude variation of an ultrasonic beam incident on the surface. The robustness of the system is examined by applying the technique to different machined surfaces and investigating the effect of various coupling fluids. Experimental results show that the technique is applicable to the surfaces produced by most production processes. In addition, the capability of in-process measurements is demonstrated by adapting the system to a CNC machining center. Results show in-process measurements correlate well with off-line profilometer data. Tolerance to machine vibration is also shown by comparing the measurement data with the machine spindle on and off.

The quality management system (QMS) and environmental management system (EMS) are currently being widely developed in laboratories, and have contributed to significant improvements in measurement management processes and client opinion. The purpose of this work is to establish appropriate methodologies for assessing the turbidity measurement that guarantee the quality of the results concerning precision and accuracy and also to test the service performance of the Water Analysis Laboratory of the Engineering Department (LAADEG) of Federal University of Lavras (UFLA). The research assessed two bench turbidimeters "A and B" through a statistical process capability study, analyzing the potential capability indexes (Cp) and performance capability (Cpk). We identified special causes also present in the control through non predetermined random patterns. After the studies, it was found that turbidimeter "B" should be used for all turbidity measurements in LAADEG, since its precision was higher than turbidimeter "A".

<p><strong>Purpose:</strong> The paper centres on process capability and its relation to data contamination. Process capability may be distorted due to imprecise data. The paper analyses to what extent capability changes reflect problems in data so that the changes can be attributed to data sampling rather than the true performance of the process. This is important because it is usually much simpler to increase the precision of data sampling than the process itself.</p><p><strong>Methodology/Approach:</strong> The paper has two major parts. In part one, effect of data contamination on the observed process characteristic is analysed. The effect is analysed using data obtained from simulated random drawings and the chi-squared test. In the other part, reaction of capability to data contamination is observed. The capability is measured by a univariate capability index.</p><p><strong>Findings:</strong> Regarding the sensitivity of the index to contamination, it is different depending on the capability before the contamination. This leads to conclusions about when the company using the index should focus more on the way the data is measured, and when it should focus more on improving the process in question. The analysis shows that if the company is used to high levels of capability and records its drop, it is worth analysing its measurement system first, as the index is at higher levels more sensitive to data contamination.</p><p><strong>Research Limitation/implication:</strong> The study concerns a single univariate index, and the contamination is modelled with only several probability distributions. </p><p><strong>Originality/Value of paper:</strong> The findings are not difficult to detect, but are not known in practice where companies do not realize that problems with their process capability may sometimes lie in the data they use and not in the process itself.</p>

This article studies the influence of enterprise core competence on IT application maturity (ITAM) from the perspectives of management institutional and process management capabilities. The roles of firm ownership and international organization of standard (ISO) certifications are also studied. Based on reliable and valid measurements of IT applications maturity, management institutional capability, and process management capability, the authors collect corresponding data from 123 companies in China. They find a positive relationship between capabilities and ITAM. Management institutional capability has a stronger relationship with ITAM in Chinese state-owned enterprises or public companies; while multinational companies or joint ventures witness a stronger relationship with process management capability. ISO helps companies with low management institutional capability to improve ITAM. However, for companies with higher management institutional capability, ISO mitigates the relationship and poses a shift of the importance to process management capability in improving ITAM.

A nonparametric pattern classification method is introduced for fault diagnosis of complex systems. This method represents the fault signatures by the columns of a multi-valued influence matrix (MVIM), and uses adaptation to cope with fault signature variability. In this method, the measurements are monitored on-line and flagged upon the detection of an abnormality. Fault diagnosis is performed by matching this vector of flagged measurements against the columns of the influence matrix. The MVIM method has the capability to assess the diagnosability of the system, and use that as the basis for sensor selection and optimization. It also uses diagnostic error feedback for adaptation, which enables it to estimate its diagnostic model based upon a small number of measurement-fault data.

PurposeThe purpose of this paper is to seek effective measurement methods that reflect the real value of process capital.Design/methodology/approachFrom a system model perspective, the authors refined the existing knowledge of process measurement by distinguishing three kinds of indicator for the value of process capital: input, output, and the capability to manage process capital. The design of this study, therefore, incorporates a longitudinal analysis of the content of process capital and traces its evolution by attaching a monetary value to activities and assets.FindingsThe tested results reveal that the input measure is a less effective measure for process capital, while the output measure is a valid one for measuring operational and managerial performance of process capital. The capability to manage process capital can predict all dimensions of process capital in both the short‐ and long‐term periods.Practical implicationsA practical view of process capital enhances the current understanding of process capital by highlighting the sustainability of process value and the validity of measuring output and management capability of the process capital. Second, the study results also explain the productivity paradox because of the complexity of the hidden cost of process input and the distinctive capability of organizations in managing technology and complementary resources. Finally, the system view of process capital, from input through process to output of the process capital, with operationalized measures, provides a useful reference for examining intellectual capital.Originality/valueThe findings offer a more robust definition of process capital as a firm's established capability to exploit the knowledge of business processes and organize resources in designing and managing business activities for sustained value.

In the concept of the process signature, the relationship between a material load and the modification remaining in the workpiece is used to better understand and optimize manufacturing processes. The basic prerequisite for this is to be able to measure the loads occurring during the machining process in the form of mechanical deformations. Speckle photography is suitable for this in-process measurement task and is already used in a variety of ways for in-plane deformation measurements. The shortcoming of this fast and robust measurement technique based on image correlation techniques is that out-of-plane deformations in the direction of the measurement system cannot be detected and increases the measurement error of in-plane deformations. In this paper, we investigate a method that infers local out-of-plane motions of the workpiece surface from the decorrelation of speckle patterns and is thus able to reconstruct three-dimensional deformation fields. The implementation of the evaluation method enables a fast reconstruction of 3D deformation fields, so that the in-process capability remains given. First measurements in a deep rolling process show that dynamic deformations underneath the die can be captured and demonstrate the suitability of the speckle method for manufacturing process analysis.

Measurement of the design process is an issue facing business and academic practitioners alike. This paper outlines an approach used to formalize design process measurement within a large electromechanical original equipment manufacturer (OEM) by applying a derivation of the Carnegie-Mellon/Software Engineering Institute systems engineering capability maturity model(R) (SE-CMM(R)), entitled the process capability model-mechanical design (PCM-MD). This new model was created using a similar structure and format of questions as the SE-CMM(R), with modifications to suit mechanical engineering terminology. This was then applied to the mechanical engineering design department of the partner company where it was successfully piloted and then reapplied to produce a picture of how the effectiveness or otherwise of the processes associated with their multidisciplinary mechanical design function altered over time. This work provided the building blocks for further detailed studies to be carried out at other sites in the same company and within the mechanical engineering departments of other firms.

Abstract To consistently produce high quality products, a quality management system must be practically implemented in every organization. One of its core instrument is to ensure the capability of the measurement systems, which are the basis for decisions regarding the behavior of the product critical quality characteristics. Base on requirements of the quality management system, a Measurement System Analysis should be conducted for all measurement system which are mentioned in the organization quality plan. Most problematic measurement system issues come from measuring discrete data, which are usually the result of human judgment (subjective decision) when categorizing products such as good/bad (visual inspection). It was the aim of this paper to address such an issue presenting a case study made in a local company from the Sibiu region, in order to evaluate how capable are the appraisers to visually inspect steel chains. The results were analyzed using MINITAB statistical software with its module called Attribute Agreement Analysis. The conclusion was that the inspection process must be improved by operator training, developing visual aids/boundary samples, establishing standards and set-up procedures.

A feasibility analysis is performed for the development and integration of a near-field scanning optical microscope (NSOM) tip–photodetector operating in the visible wavelength domain of an atomic force microscope (AFM) cantilever, involving simulation, processing, and measurement. The new tip–photodetector consists of a platinum–silicon truncated conical photodetector sharing a subwavelength aperture, and processing uses advanced nanotechnology tools on a commercial silicon cantilever. Such a combined device enables a dual-mode usage of both AFM and NSOM measurements when collecting the reflected light directly from the scanned surface, while having a more efficient light collection process. In addition to its quite simple fabrication process, it is demonstrated that the AFM tip on which the photodetector is processed remains operational (i.e., the AFM imaging capability is not altered by the process). The AFM–NSOM capability of the processed tip is presented, and preliminary results show that AFM capability is not significantly affected and there is an improvement in surface characterization in the scanning proof of concept.

Capability indexes of several types belong to the most common tools used for evaluation of the measuring instruments performance over a certain period of time. The indices differ by calculation method, properties as well as by intended use. But their design principle is approximately the same. The ratio of prescribed (required) accuracy and really achieved process accuracy is always observed. However, this evaluation represents only a part of the overall measurements management system. The suitability of capability indexes for the evaluation of CMMs accuracy over a time. After analyzing the results we had found machine capability indexes good method for evaluation of Coordinate Measuring Machines (CMM) accuracy over a certain time interval. CMM are high accuracy and capable to perform the measurement of lengths, machine capability indexes helps to determine the ability for coordinate measuring machine between tolerance limits and engineering specifications, but the use of x-control charts to get and keep processes under control.

There are generally complex features with large curvature or narrow space on surfaces of complicated tiny parts, which makes high-precision measurements of their three-dimensional (3D) overall profiles a long-lasting industrial problem. This paper proposes a feasible measurement solution to this problem, by designing a cradle-type point-scanning five-axis measurement system. All the key technology of this system is also studied from the system construction to the actual measurement process, and the measurement accuracy is improved through error calibration and compensation. Finally, the feasibility is proved by engineering realization. The measurement capability of the system is verified by measuring workpieces such as cross cylinders and microtriangular pyramids.

The importance of leadership capability (LC) and knowledge management (KM) are well recognised in the popular and academic press to achieve competitive advantage. Although organisations are applying many skills and practices to address the problems for the achievement of competitive advantage, but unable to focus on the measurement and relationship aspects of LC and KM. Many organisations are succeeding and achieving their goals and targets generally with their human resource skills, and particularly with LC and KM. But there are no methodologies for their measurement aspects to plan for the required human resource with necessary competencies as per the desired organisational goals. A research is carried out to develop a methodology for the measurement and relationship aspects of the LC and KM. As the main purpose of this paper is to investigate a relationship between LC and KM, a research study is carried out in: (i) development of process models for LC and KM, (ii) developed an instrument for measuring the LC and KM efforts and (iii) investigated for the relationship between LC and KM. Based on the survey of 247 managers in the three major public sector undertakings, the LC and KM skills have been measured, and analysed for their relationship. The analysed data interprets that there is a positive correlation relationship between the LC and KM. Finally, this research limitations and implications have been examined.
