ISQI certification TMMi-P_Syll2020 iSQI Study Notes

The description provided, "Testing is a thoroughly defined, well-founded, and measurable process. Testing is perceived as evaluation; it consists of all lifecycle activities concerned with checking products and related work products," corresponds to TMMi Level 4, which is labelled "Measured." At this level, testing processes are quantitatively measured, and there is a strong focus on evaluating product and process quality using quantitative metrics. Testing is integrated throughout the lifecycle and becomes a predictable, measurable process that supports organisational goals.

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​.

In the TMMi framework,specific goalscan indeed havedifferent specific practicesacross maturity levels. The practices associated with a specific goal evolve as an organization matures, reflecting the need for more sophisticated approaches at higher levels of maturity. For example, test design practices atLevel 2 are more basic compared to the more comprehensive practices at Level 3, which include integration with other lifecycle processes.

The other statements are incorrect. For instance, sub-practices are informative and not mandatory, and while generic goals have the same set of practices across process areas, specific goals vary by maturity level.

The absence of amaster test plan spanning multiple test levelspoints to a weakness in theTest Lifecycle and Integrationprocess area, which is aTMMi Level 3process area. This process area focuses on ensuring that testing is integrated throughout the development lifecycle and includes the development of comprehensive test plans (including master test plans) that cover multiple test levels and align with the overall testing strategy.
