TMMi-P_Syll2020 Exam Dumps : TMMi - Test Maturity Model Integration Professional

At TMMi Level 3, the organisation's test processes become more structured, managed, and standardised. It requires defining and implementing a consistent set of test processes across projects and organisational units. One key factor for achieving TMMi Level 3 is the integration of process asset development.

"Process Asset Development" is directly related to establishing organisational test process assets, which is a critical element at TMMi Level 3. This practice area includes developing and maintaining organisational process assets, which encompass the standard processes that will be used across various projects. These assets are required to ensure that testing is a well-defined, repeatable, and efficient process throughout the organisation.

According to the TMMi Framework 1.3, process asset development supports the implementation of defined and repeatable processes and helps with creating guidelines for tailoring processes across the organisation. It provides the necessary framework for consistency in test planning, execution, and reporting, which are key at this maturity level​.

This practice aligns with the goals of TMMi Level 3, where the focus is on defining, standardising, and integrating the test lifecycle within the overall development lifecycle, thus ensuring that test processes are well-established across the organisation. Hence, Process Asset Development (Option B) is critical for the organisation's progression to TMMi Level 3.

In an Agile context, some practices from TMMi levels 4 and 5 might be considered less relevant or adjusted to fit the Agile methodology. Specifically, at TMMi level 5, testing with statistical methods may indeed be less relevant. In Agile projects, operational profiles or usage models, which are essential to perform statistically valid testing, are often not utilised. Agile methodologies focus more on incremental development and continuous feedback loops, which do not typically rely on statistical sampling methods. Therefore, the statement that "Agile projects normally do not use operational profiles or usage models of a product on which to base statistically valid inferences to help create a representative sample of tests, thus the TMMi level 5 specific goal 'Testing is performed using Statistical Methods' is considered not relevant in an Agile context" is true​.

The assessment described, where only interviews are used to collect evidence, aligns with aninformal TMMi assessment. Informal assessments are more flexible and do not require documentary evidence to corroborate interview data. They provide an indicative view of the organisation’s maturity but do not result in a formal maturity rating or certification​​.
