Study On New Sampling Plans And Optimal Integration With Proactive Maintenance In Production Systems, Sinan Obaidat

Graduate Theses and Dissertations

Sampling plans are statistical process control (SPC) tools used mainly in production processes. They are employed to control processes by monitoring the quality of produced products and alerting for necessary adjustments or maintenance. Sampling is used when an undesirable change (shift) in a process is unobservable and needs time to discover. Basically, the shift occurs when an assignable cause affects the process. Wrong setups, defective raw materials, degraded components are examples of assignable causes. The assignable cause causes a variable (or attribute) quality characteristic to shift from the desired state to an undesired state.

The main concern of sampling is …

Discovering Software Reliability Patterns Based On Multiple Software Projects, Yi Liu, Gerald Adkins, Jeng-Foung Yao, Gita Williams

Journal of International Technology and Information Management

Discovering patterns that indicate software reliability provides valuable information to software project managers. Software Quality Classification (SQC) modeling is a methodology that can be used to discover reliability patterns of large software projects. However, the patterns found by SQC modeling may not be accurate and robust owing to insufficient information used in the training process. This study compares two genetic programming-based SQC models using different volumes of data. These data were extracted from seven different NASA software projects. The results demonstrate that combining data from different projects can produce more accurate and reliable patterns.

An Application Of The Deming Management Method For Information Technology Projects, Jack T. Marchewka

Journal of International Technology and Information Management

Although the ideas and teachings of W. Edwards Deming have been implemented in organizations world- wide for over the past 50 years, only three studies have empirically tested a theoretical model grounded in the Deming Management Method. These studies focused on the manufacturing and services area. Today, quality management continues to be an area of interest both in project management and software engineering. The focus of this study is to test the Deming Management Method in information technology (IT) projects. A survey of 63 IT professionals provides empirical support for the Deming Management Method and its application to IT projects. …

Information Systems Service Quality Measurement: The Evolution Of The Servqual Instrument, Dwayne Whitten

Journal of International Technology and Information Management

Due to the increasing service component of information technology, service quality measurement has become increasingly important as IS practitioners attempt to increase service quality to customers. The measurement of service quality in IS evolved from the research done in the marketing literature. The SERVQUAL instrument has evolved to become the most commonly used measurement instrument in both IS and marketing. Although commonly used, the SERVQUAL instrument is not without criticism. This paper describes the SERVQUAL instrument, its criticisms and support, and finally the SERVPERF instrument, a variation of the SERVQUAL instrument which is an attempt at improving upon the SERVQUAL …
