To which TMMi maturity level does this description apply?

Study the following description:

“Testing is multi-levelled: there are component, integration, system and acceptance test levels. For each identified test level there are specific testing objectives defined in the organization-wide or program-wide test strategy. The processes of testing and debugging are differentiated.”

To which TMMi maturity level does this description apply?
A . Level 2
B . Level 3
C . Level 4
D . Level 5

Answer: A

Explanation:

The description provided―where testing is multi-level, with distinct test levels (component, integration, system, and acceptance), and where the processes of testing and debugging are differentiated―applies to TMMi Level 2 (Managed). At this maturity level, testing is separated from debugging, and there are formalized processes for different testing levels. A company-wide or program-wide test strategy is established, and specific testing objectives are defined for each test level.

Reference: The TMMi Level 2 framework defines structured testing with multiple levels, including component, integration, system, and acceptance testing, as well as the separation of testing and debugging.
