TAILIEUCHUNG - Lecture Software engineering (7/e): Chapter 21 – Ian Sommerville

Chapter 21 - Software evolution. In this chapter, the learning objectives are: To explain why change is inevitable if software systems are to remain useful, to discuss software maintenance and maintenance cost factors, to describe the processes involved in software evolution, to discuss an approach to assessing evolution strategies for legacy systems. | Software evolution Objectives To explain why change is inevitable if software systems are to remain useful To discuss software maintenance and maintenance cost factors To describe the processes involved in software evolution To discuss an approach to assessing evolution strategies for legacy systems Topics covered Program evolution dynamics Software maintenance Evolution processes Legacy system evolution Software change Software change is inevitable New requirements emerge when the software is used; The business environment changes; Errors must be repaired; New computers and equipment is added to the system; The performance or reliability of the system may have to be improved. A key problem for organisations is implementing and managing change to their existing software systems. Importance of evolution Organisations have huge investments in their software systems - they are critical business assets. To maintain the value of these assets to the business, they must be changed and .
