Which statement about Appraisal Team Members (ATMs) is true?

The statement regarding Appraisal Team Members (ATMs) being assigned specific roles and tasks by the team leader is accurate because ATMs play a crucial role in the appraisal process defined by the CMMI framework. Each member of the appraisal team is selected based on their skills, knowledge, and experience that align with the objectives of the appraisal. The team leader organizes the team and designates specific roles and responsibilities to ensure that the appraisal activities are effectively carried out.

By assigning distinct tasks, the team leader ensures that each ATM is clear on their contributions, thereby improving the overall efficiency and focus of the appraisal. This structured approach enables the team to assess the organization's processes thoroughly and provides a framework for gathering necessary evidence and information.

While the other statements suggest a more haphazard approach to the roles of ATMs, they do not accurately reflect the organized nature of appraisal teams as prescribed by CMMI guidelines. Proper training and experience are beneficial for ATMs to contribute effectively, and tasks should be clearly defined to ensure a systematic appraisal process.
