| Question 71 |
Modifying the software by restructuring is called
| Adaptive maintenance | |
| Corrective maintenance | |
| Perfective maintenance | |
| Preventive maintenance |
Question 71 Explanation:
Four types of change are encountered during the support phase:
→ Correction. Even with the best quality assurance activities, it is likely that the customer will uncover defects in the software. Corrective maintenance changes the software to correct defects.
→ Adaptation. Over time, the original environment (e.g., CPU, operating system, business rules, external product characteristics) for which the software was developed is likely to change. Adaptive maintenance results in modification to the software to accommodate changes to its external environment.
→ Enhancement. As software is used, the customer/user will recognize additional functions that will provide benefit. Perfective maintenance extends the software beyond its original functional requirements.
→ Prevention. Computer software deteriorates due to change, and because of this, preventive maintenance, often called software reengineering(restructuring), must be conducted to enable the software to serve the needs of its end users. In essence, preventive maintenance makes changes to computer programs so that they can be more easily corrected, adapted, and enhanced.
