Which type of appraisal can have its scope reduced by an average of 1/3 following a Benchmark appraisal?

The correct answer is that a Sustainment appraisal can have its scope reduced by an average of 1/3 following a Benchmark appraisal. In the context of CMMI, a Sustainment appraisal is typically used to verify that the organization continues to meet its process improvement goals and maintains its mature practices over time.

After a Benchmark appraisal, which serves as a comprehensive evaluation against best practices and may establish baseline performance measures, organizations can identify areas of strength and opportunity. This allows for a more focused approach in subsequent Sustainment appraisals. Since the organization has already undergone a detailed benchmarking process, the Sustainment appraisals can concentrate on specific areas needing attention rather than reviewing all processes thoroughly, thus reducing the scope of the appraisal.

This is beneficial because it streamlines the appraisal process, making it less time-consuming and resource-intensive while still ensuring that essential practices are preserved and improved upon.
