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

The description provided—where testing ismulti-level, with distinct test levels (component, integration, system, and acceptance), and where the processes of testing and debugging are differentiated—applies toTMMi 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.

TheTMMi Level 2framework defines structured testing withmultiple levels, including component, integration, system, and acceptance testing, as well as the separation of testing and debugging​​.

Thecommunication skills of testersis least likely to be improved using the TMMi model. While TMMi focuses on improving structured test processes, including static testing (such as reviews), unit testing, integration testing, and the management of test environments, it does not explicitly address the soft skills, such as communication, that testers may need toeffectively interact with stakeholders. These skills are typically developed through other training or team-building initiatives, not through process improvements outlined by TMMi.

Thedebugging-oriented phaseof the evolutionary testing model aligns closely with TMMi Level 1 (Initial). At TMMi Level 1, testing is often chaotic and is not formally separated from debugging. The primary focus is on finding and fixing bugs, which reflects the characteristics of the debugging-oriented phase described in the Gelperin and Hetzel evolutionary testing model. Testing at this level lacks structure and is mainly an ad hoc activity aimed at removing defects from the software.

A typical business reason for starting a test improvement program is to achievehigher productivity. Test process improvements can lead to better efficiency in test execution, reduction of defects, and optimised resource usage, all of which contribute to the overall productivity of the organisation. By improving testing processes, organisations can reduce time-to-market and minimise costs associated with fixing defects post-production, which in turn boosts productivity.

In the context of TMMi and test improvement programs, anindirect benefitrefers to outcomes that are not directly tied to the technical improvement of the testing process but affect the overall success of the organization in less measurable ways.

Increased personnel motivationis considered anindirect benefitof a test improvement program because it boosts team morale and engagement, leading to better productivity in the long run. This is different from direct benefits such asimprovements in defect detectionortest execution lead-time, which are quantifiable metrics directly related to the testing process.

TMMi References:

Direct benefitssuch as defect detection rates and test execution speed are frequently mentioned in TMMi as measurable outcomes from process improvement efforts.

Indirect benefits, like improved motivation, are acknowledged as part of the cultural and organizational improvements that can come from a well-executed test improvement strategy​​.

In theInitiating phaseof a test improvement cycle, one of the key activities is toCharter Infrastructure. This activity involves setting up the structure needed to support the improvement effort, such as establishing a project board and defining responsibilities. This phase focuses on creating the foundational support for the test improvement initiative.

The process areaAdvanced Reviewsbelongs to TMMi Level 4 (Measured). At this maturity level, the focus is on quantitatively measuring and managing product quality, and advanced review techniques are employed to integrate peer reviews (static testing) with dynamic testing. These advanced reviews play a key role in ensuring that product quality is assessed early in the lifecycle and that testing is driven by measurable goals.

The three TMMi Level 5 process areas are as follows:

Defect Prevention(A): The key specific goal here is todetermine common causes of defects. This process involves analysing defect patterns and establishing actions to prevent similar defects in the future.

Quality Control(B): This area focuses onevaluating new testing technologies to determine their impact on the testing process. Statistical methods help predict product quality, and these evaluations drive improvements in the test process.

Test Process Optimization(C): The goal here is toestablish a statistically controlled test process, where baselines are set, and improvements are implemented in an orderly manner​​​.
