William Hook DeLone (born September 28, 1946) is an American organizational theorist, and Professor at the American University, Department of Information Technology, known for his work with Ephraim R. McLean on the information systems success model and on "measurement of information systems effectiveness." [1] [2]
DeLone obtained his BS from the Villanova University, his MS from Carnegie-Mellon University, and his PhD in Computers and Information Systems in 1983 from the University of California, Los Angeles with the thesis, entitled "Determinants of success for small business computer systems."
After his graduation DeLone started his academic career, and moved to the Kogod School of Business at the American University in 1992, where he is appointed Professor at the Department of Information Technology.
Delone's research interests are in the fields of the "coordination effectiveness and project success in globally distributed software development teams... [and] the effective deployment of information and communications technology in developing countries." [3]

Lean manufacturing is a method of manufacturing goods aimed primarily at reducing times within the production system as well as response times from suppliers and customers. It is closely related to another concept called just-in-time manufacturing. Just-in-time manufacturing tries to match production to demand by only supplying goods that have been ordered and focus on efficiency, productivity, and reduction of "wastes" for the producer and supplier of goods. Lean manufacturing adopts the just-in-time approach and additionally focuses on reducing cycle, flow, and throughput times by further eliminating activities that do not add any value for the customer. Lean manufacturing also involves people who work outside of the manufacturing process, such as in marketing and customer service.
An information system (IS) is a formal, sociotechnical, organizational system designed to collect, process, store, and distribute information. From a sociotechnical perspective, information systems comprise four components: task, people, structure, and technology. Information systems can be defined as an integration of components for collection, storage and processing of data, comprising digital products that process data to facilitate decision making and the data being used to provide information and contribute to knowledge.
August-Wilhelm Scheer is a German Professor of business administration and business information at Saarland University, and founder and director of IDS Scheer AG, a major IT service and software company. He is known for the development of the Architecture of Integrated Information Systems (ARIS) concept.
Operations management is concerned with designing and controlling the production of goods and services, ensuring that businesses are efficient in using resources to meet customer requirements.
Computer user satisfaction is the attitude of a user to the computer system they employ in the context of their work environments. Doll and Torkzadeh's (1988) definition of user satisfaction is, the opinion of the user about a specific computer application, which they use. In a broader sense, the definition of user satisfaction can be extended to user satisfaction with any computer-based electronic appliance. However, scholars distinguish between user satisfaction and usability as part of Human-Computer Interaction. Successful organisations have systems in place which they believe help maximise profits and minimise overheads. It is therefore desirable that all their systems succeed and remain successful; and this includes their computer-based systems. According to key scholars such as DeLone and McLean (2002), user satisfaction is a key measure of computer system success, if not synonymous with it. However, the development of techniques for defining and measuring user satisfaction have been ad hoc and open to question. The term Computer User Satisfaction is abbreviated to user satisfaction in this article.

Gupta has worked in academics, private companies, and international organizations in positions that involved analysis and leveraging of opportunities at the intersection of technology and business, as well as the design, development, and implementation of prototype systems that led to widespread adoption of new techniques and technologies.
Computer-aided lean management, in business management, is a methodology of developing and using software-controlled, lean systems integration. Its goal is to drive innovation towards cost and cycle-time savings. It attempts to create an efficient use of capital and resources through the development and use of one integrated system model to run a business's planning, engineering, design, maintenance, and operations.
The project management triangle is a model of the constraints of project management. While its origins are unclear, it has been used since at least the 1950s. It contends that:
Lynn Gref is an American technologist and systems engineer, who has done pioneering work in missile systems; command, control and communications (C3) systems; and satellite systems. He and Dr. William Spuck developed the Rapid Development Methodology (RDM) that was employed in the development of a number of C3 systems for the U.S. Department of Defense. RDM is a form of software development classified as iterative and incremental development. A primary distinction of RDM is that the user is left with a usable capability at the end of every iteration. He pioneered the development of C3 systems using the Ada programming language. He has coauthored a number of reports as a member the Army Science Board (ASB) and as a committee member for the Naval Studies Board of the United States National Academy of Sciences.
The information systems success model is an information systems (IS) theory which seeks to provide a comprehensive understanding of IS success by identifying, describing, and explaining the relationships among six of the most critical dimensions of success along which information systems are commonly evaluated. Initial development of the theory was undertaken by William H. DeLone and Ephraim R. McLean in 1992, and was further refined by the original authors a decade later in response to feedback received from other scholars working in the area. The IS success model has been cited in thousands of scientific papers, and is considered to be one of the most influential theories in contemporary information systems research.
