Dynamic Planning and Control of Software Maintenance: A Fiscal Approach

摘要

Until recently, much of the budget planning for software systems has been primarily targeted at costs incurred during the development phase. However, with increasing software system life span and complexity, maintenance costs have become a more prevalent concern. As a result of necessary corrections for design errors and evolutionary maintenance, post-delivery investment in software systems now requires a greater proportional share of the life-cycle costs. In this research, various methodologies and system factors relating to software cost accounting are reviewed with the intent of developing a cost control model for arriving at a well-structured view for the management of the maintenance phase of the software life-cycle. The model proposed embodies a planning concept for establishing a maintenance strategy and a control concept for analyzing manloading requirements during the maintenance phase. (Author)
