Question

Which one of these are not software maintenance activity ?

• A. Error correction
• B. Adaptation
• C. Implementation of Enhancement
• D. Establishing scope

Answer 1

The answer must be D

The maintenance can be divided into four types:

1. Correction: To correct defects.
2. Adaptation:  If external environment (e.g., CPU, operating system, business rules) changes, software should be modified.
3. Perfective: extends the software by adding extra functions. This type of maintenance needs maximum effort.
4. Prevention: Due to the changes by other maintenances software can be easily degraded. Preventive maintenance makes changes to computer programs so that they can be more easily corrected, adapted, and enhanced.
