"No matter where you are in systems life cycle, the system will change and the desire to change it will persist throughout the life cycle"

Bernstorff et al.(1980)

In the late 1970s, a famous and widely cited survey study by Lientz and Swanson, exposed the very high fraction of life-cycle costs that were being expended on maintenance. They categorized maintenance activities into four classes:

• Adaptive - modifying the system to cope with changes in the software environment (DBMS, OS)
• Perfective - implementing new or changed user requirements which concern functional enhancements to the software
• Corrective - diagnosing and fixing errors, possibly ones found by users
• Preventive - increasing software maintainability or reliability to prevent problems in the future

The survey showed that around 75% of the maintenance effort was on the first two types, and error correction consumed about 21%.
