iSQI TMMi - Test Maturity Model Integration Professional TMMi-P_Syll2020 Exam Dumps: Updated Questions & Answers (July 2025)

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.

The process areaNon-functional Testingat TMMi Level 3 focuses on performing a structured test execution process for non-functional attributes of the system. The specific goals for this process area include:

Perform a Non-functional Product Risk Assessment

Perform Non-functional Test Analysis and Design

Perform Non-functional Test Implementation

The creation of a specificnon-functional test planisnotexplicitly listed as a goal within this process area, although defining a non-functional test approach is addressed. Hence,"Establish a Non-functional Test Plan"(B) isnota specific goal of the Non-functional Testing process area​​.

In theDefect Preventionprocess area at TMMi Level 5, one of the key specific goals (SG2) is to prioritise and define actions to systematically eliminate the root causes of defects. This involves proposing solutions to address common defect causes that have been identified during causal analysis. These solutions aim to prevent defects from reoccurring across the development lifecycle.

The specific practice"Define product risk categories and parameters"is part of theTest Policy and Strategyprocess area in TMMi. This practice involves identifying and categorizing the product risks to guide testing efforts and establish a clear understanding of potential product issues. Product risk categories help in determining the focus areas for testing, ensuring that testing is prioritized based on business and technical risks.

TMMi References:

The practice of defining product risk categories is directly linked to theTest Policy and Strategyprocess area at TMMiLevel 2, where risk-based testing approaches are established​​.

This statement is false because the CMMI does not have defined levels specifically for testing maturity. The CMMI model is more general and focuseson overall process improvement across various disciplines, including but not limited to testing. CMMI includes practices like verification and validation but does not specifically address a structured path to testing maturity, unlike TMMi, which defines specific levels for testing process maturity. Therefore, statement D is incorrect.

The specific practice "Testers review test basis documents" belongs to thePeer Reviewsprocess area. At TMMi Level 3, the Peer Reviews process area involves static testing activities where testers and other stakeholders review key work products, such as requirements and design documents, to identify defects early in the lifecycle. By involving testers early through these reviews, organisations can enhance testability and improve overall quality.

"Provide Necessary Test Training" is part of theTest Training Programprocess area, not theTest Organizationprocess area. Test Organization focuses on establishing a structured group responsible for testing, defining roles, career paths, and implementing process improvements. Therefore, providing test training is not a specific goal of Test Organization but rather falls under the Test Training Program process area.

TheDebugging-oriented phasefrom Gelperin and Hetzel's evolutionary testing model is associated withMaturity Level 1 "Initial"of TMMi. At this maturity level, testing is not yet a distinct and well-defined process but is often interleaved with debugging. Organizations at this level have chaotic and ad-hoc testing activities, with no separation between testing and debugging.

Maturity Level 1organizations lack formal processes, and testing is often reactive, performed alongside fixing bugs in the code. This is in line with the debugging-oriented phase, where testing and debugging are seen as part of the same activity.

TMMi References:

TheTMMi frameworkdraws directly from the evolutionary model of Gelperin and Hetzel, associating theDebugging-oriented phasewith Level 1, which describes a chaotic, unmanaged testing environment​​.

The correct order of TMMi maturity levels fromlow to highis:

Managed(Level 2): Testing becomes a managed and separate process from debugging, with formal strategies and plans.

Defined(Level 3): Testing is fully integrated into the development lifecycle, with standardized processes across projects.

Measured(Level 4): Testing processes are measured quantitatively, and product quality is evaluated with formal metrics.

This sequence reflects the increasing maturity and sophistication of an organization's testing processes as they progress through the levels.

TMMi References:

The TMMi maturity levels follow the order ofManaged (Level 2),Defined (Level 3), andMeasured (Level 4)​​.

This statement isFALSEbecause in Agile environments, acentralized process improvement projectmay not align with the decentralized, self-organizing nature of Agile teams. Agile emphasizes local, team-driven improvements rather than a top-down, centralized approach. Continuous, local improvements within Agile teams are more suitable than attempting to manage improvements across the organization in a centralized manner, which is more characteristic of traditional environments.

TMMi References:

In Agile contexts, improvement actions are typically implemented locally within teams rather than through a centralized project, aligning with Agile's principles of team autonomy​​.
