PHYSICS 102 Lecture Notes - Lecture 12: Reverse Engineering, Systems Development Life Cycle, Xml
Document Summary
14. 1 explain and contrast four types of maintenance. 14. 2 describe several factors that influence the cost of maintaining an information system and apply these factors to the design of maintainable systems. 14. 3 describe maintenance management issues, including alternative organizational structures, quality measurement, processes for handling change requests, and configuration management. Once an information system is installed, the system is essentially in the maintenance phase of the systems development life cycle (sdlc). Also shown in figure 14-1, four major activities occur within maintenance: obtaining maintenance requests, transforming requests into changes, designing changes, implementing changes. The deliverables and outcomes from the process are the development of a new version of the software and new versions of all design documents developed or modified during the maintenance process. Maintenance [changes made to a system to fix or enhance its functionality. ] We will describe various types of maintenance, factors influencing the complexity and cost of maintenance, and alternatives for managing maintenance.
