Toward an Improved FIPS Cost-Benefit Methodology. Phase 2. Descriptive Models - General Purpose Application Software Development and Maintenance

摘要

This report presents a functional-flow descriptive model that can be used to categorize the application software (ASOF) development and maintenance activities of Federal data processing facilities. ASOF-related activities may be conceptually represented in descriptive model form by combining one or more of the basic model tasks. The comprehensive framework for ASOF development and maintenance provided by the descriptive model can be used in the identification of impacts from standards and guidelines and in the preparation of cost-benefit impact assessments. The framework provides both macro and micro levels of detail in order to link the descriptive models to additional data processing issues.
