“…But, as a complex intellectual process, software systems development and production seem to differ in many aspects from conventional industrial and agricultural production processes which utilize production resources and technology to produce the predetermined products. However, Banker (1984), Banker, Datar, andKemerer (1991, 1994); Banker, Chang, and Kemerer (1994), Boehm (1981), Ho and McDevitt (1990), Hu (1994), and Putnam and Myers (1992) have used the fundamental principles of economic production theory to explain and predict certain behavior of software development. The main motivation behind these studies is to understand the relationships among the significant factors (such as software size, complexity, functionality, manpower, skills, and time) in software systems development in order to determine the optimal levels of these factors in the sense that a software system may be delivered with minimum cost, within the scheduled time duration, and with the predetermined functionality and quality.…”
