Four types of change occur in the support phase. Which one is not one?
Show answer Hide answer
Answer: A. Translation
Explanation
Translation is not recognized as a standard category of maintenance change in software engineering. The four standard maintenance categories are correction, adaptation, enhancement, and prevention. Support phase activities focus on fixing bugs, adapting to environments, and improving code. Software maintenance consumes a major portion of the total lifecycle cost for large systems. Corrective maintenance fixes discovered defects after the software is deployed to production. Adaptive maintenance updates software to run on new hardware or operating system versions.
Maintenance engineers track change categories to measure long-term software stability and health. Preventative maintenance refactors code to reduce future failures and improve maintainability. Understanding maintenance types helps organizations budget appropriate resources for ongoing support. Correction involves fixing defects and errors discovered by users after system deployment. Adaptation modifies software to ensure compatibility with changing external system environments. Prevention refactors code proactively to prevent future software failures and technical debt.
