Consideration of maintenance objectives in the design and development of software

摘要

AbstractFactors are addressed that affect the total cost of developing, deploying and supporting software systems. The experiences are drawn from a large computerized facility incorporating over half a million lines of application code. The operational and support activities dominate the cost considerations over program life.Techniques are presented in this paper to ensure early design considerations of these operational and support activities and to reduce their cost. Thus, the focus is the life cycle cost factors of the system software.
