TMMi-P_Syll2.1 Sample Questions Answers

The specific practice "Maintain horizontal traceability with requirements" is part of the Test Design and Execution process area in TMMi. This process area ensures that there is traceability between test conditions, test cases, and requirements to ensure comprehensive test coverage. Horizontal traceability guarantees that test cases can be traced back to the specific requirements they are intended to verify, which is critical for managing and ensuring the quality of the testing process.

TMMi References:

The Test Design and Execution process area includes practices that ensure test artifacts are traceable to requirements, supporting effective test coverage​​.

A direct benefit of a test improvement program is higher productivity. When test processes are streamlined, better test planning, design, and execution can lead to reduced testing times, fewer defects, and quicker turnaround of quality products. This has a direct impact on organisational efficiency, allowing for more effective use of resources and time.

The specific goal "Coordinate the Peer Review Approach with the Dynamic Test Approach" belongs to the process area Advanced Reviews at TMMi Level 4. This process area builds on the Peer Reviews process area introduced at TMMi Level 3 and aims to fully integrate static and dynamic testing processes. It ensures that peer reviews (static testing) are coordinated with the dynamic test approach, ensuring consistency between the two methods and optimising product quality measurement early in the lifecycle​​.

At TMMi Level 5, the Quality Control process area becomes relevant as it focuses on statistically managing and controlling the test process. Since the organisation is already at TMMi Level 4, moving to Level 5 involves ensuring that the test process is fully predictable, measured, and statistically controlled. Quality Control is a key process area in achieving TMMi Level 5 compliance, alongside other areas such as Defect Prevention and Test Process Optimization.

In the Initiating phase of a test improvement cycle, one of the key activities is to Charter 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.

In the Acting phase of the IDEAL model, the focus is on the implementation of the proposed solutions. Activities such as refining the solution and implementing the solution are key components of this phase. These actions are based on the plan developed in the earlier phases, and they are designed to apply the solutions to achieve the desired improvements. Specifically:

Refine solutions (i) refers to improving or adjusting the solution based on feedback from pilots or initial tests.

Implement Solution (iii) refers to the full implementation of the refined solution across the test process or organisation​​.

CMMI and TMMi complement each other in many ways. While CMMI focuses on improving broader software development processes, TMMi specifically addresses testing. Implementing CMMI provides value to test organizations by enabling a structured and continuous improvement approach that can incorporate TMMi as part of the overall process.

CMMI’s continuous representation allows organizations to implement specific process areas related to testing (like verification and validation) and integrate TMMi practices for continuous improvement in their testing processes. Organizations following TMMi may also refer to CMMI practices for complementary process improvements in areas such as configuration management, planning, and performance measurement.

TMMi References:

TMMi outlines how CMMI’s process areas, such as Verification and Validation, provide critical value for testing organizations​​.

CMMI’s structure supports continuous process improvement that aligns well with TMMi’s structured approach to test process maturity​.

The process area Advanced Reviews belongs 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 statement that all defects should be analyzed to prevent as many defects as possible is FALSE. In the Defect Prevention process area at TMMi Level 5, only a subset of defects—those that are recurring or considered to be of significant impact—are analyzed. Analyzing all defects would be inefficient and not always necessary. Instead, a targeted approach is used to identify common causes of defects and implement actions to prevent their recurrence.

TMMi References:

The Defect Prevention process area is based on the analysis of a subset of defects to find and eliminate common causes​​.

The Debugging-oriented phase from Gelperin and Hetzel's evolutionary testing model is associated with Maturity 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 1 organizations 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:

The TMMi framework draws directly from the evolutionary model of Gelperin and Hetzel, associating the Debugging-oriented phase with Level 1, which describes a chaotic, unmanaged testing environment​​.

In the scenario described, testing is performed ad hoc by business analysts who do not have defined test roles or a structured career path within the organisation. The process area that needs attention here is Test Organization (TMMi Level 3). This process area is crucial for establishing a structured test group with dedicated roles and responsibilities for testing, rather than relying on business analysts for testing as a secondary task.

The Test Organization process area focuses on establishing a formalised test organisation within the company, defining test functions and responsibilities, and promoting testing as a recognised profession with defined career paths. This would address the shortcomings of the current setup by creating a dedicated, skilled testing team, thus improving the consistency and quality of testing activities within the bank​​.

Sprint retrospectives are held at the end of every sprint (not every 2-3 iterations) to evaluate the team's performance and identify opportunities for improvement. Retrospectives are a core Agile practice, but they are not considered peer reviews, which typically involve reviewing work products such as code or design documents. Peer reviews focus on product quality, while retrospectives focus more on team performance and process improvements.

The specific goal "Project Goals for Product Quality and their Priorities are Established" belongs to the Product Quality Evaluation process area, which is part of TMMi Level 4. This process area focuses on defining measurable and prioritised project goals for product quality and managing actual progress towards those goals throughout the lifecycle. Product quality goals typically include both functional and non-functional aspects of the system.

With a 40% achievement in the Test Planning process area, the rating would be "Partly achieved." According to TMMi, a process area is rated "Partly achieved" when the percentage of achievement is between 15% and 50%. This indicates that some practices have been implemented, but significant improvement is still required to meet the full requirements of the process area.

The absence of a master test plan spanning multiple test levels points to a weakness in the Test Lifecycle and Integration process area, which is a TMMi Level 3 process 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.

TMMi References:

The Test Lifecycle and Integration process area at TMMi Level 3 addresses the need for comprehensive and integrated test planning across all test levels​​.

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 specific goal during the implementation of the "Test Planning" process area at TMMi Level 2 is to establish well-founded plans for managing and performing the testing activities. One of the crucial objectives is to "Establish a Master Test Plan" at TMMi Level 3, particularly under the "Test Lifecycle and Integration" process area. This is designed to ensure that a coherent, high-level plan integrates the activities across all levels of testing.

The process includes defining a test approach based on identified risks and involves the creation of the test estimates, schedules, and plans. Test plans should align with organisational strategies and cover test activities for all relevant phases of the development cycle​​.

At TMMi Level 3, Test Lifecycle and Integration builds on the practices of Test Planning introduced at TMMi Level 2. This process area focuses on establishing a standardised test lifecycle, integrating the test process with the development lifecycle, and coordinating the testing effort across multiple levels. It also includes creating a master test plan that builds upon the risk assessments, test estimates, and approaches defined at Level 2 during Test Planning.

By further refining these practices and introducing lifecycle integration, Test Lifecycle and Integration ensures that the testing processes are consistent, well-defined, and fully embedded into the overall project lifecycle​​.

In the context of TMMi and test improvement programs, an indirect benefit refers 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 motivation is considered an indirect benefit of 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 as improvements in defect detection or test execution lead-time, which are quantifiable metrics directly related to the testing process.

TMMi References:

Direct benefits such 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​​.

A specific practice is an expected component of the TMMi model. Expected components describe what an organisation will typically implement to achieve required components, such as specific and generic goals. Specific practices are activities that are crucial for achieving the specific goals of a process area, and they are evaluated during assessments to determine whether the goals have been met.

Peer Reviews is NOT a TMMi Level 2 process area. Peer Reviews is a process area at TMMi Level 3. At Level 3, organizations formalize their testing processes, including peer reviews, which involve static testing activities like inspections and walkthroughs to identify defects early.

Test Policy and Strategy, Test Monitoring and Control, and Test Environment are all process areas at TMMi Level 2.

TMMi References:

Peer Reviews are introduced at TMMi Level 3, whereas Test Policy and Strategy, Test Monitoring and Control, and Test Environment are process areas at Level 2​​.

When implementing the Test Policy and Strategy process area in TMMi, one of the specific goals you would be targeting is to Establish Test Performance Indicators. These indicators are essential for measuring the effectiveness of testing processes and for assessing whether the organization's testing goals, as defined by the test policy, are being met.

Other goals, such as performing product risk assessments or establishing a test organization, are related to different process areas in the TMMi model.

TMMi References:

The Test Policy and Strategy process area in TMMi includes the specific goal of establishing Test Performance Indicators to measure and track testing performance​​.

A test policy is a high-level document that outlines the objectives, goals, and strategic views regarding testing. It serves to align testing activities with the organisation's business objectives and quality goals. One of the critical elements in a test policy is defining the quality levels to be achieved, which ensures that testing aligns with the expectations for product quality, both functional and non-functional. Other aspects, such as risk categories, test types, and regression testing approaches, are typically defined in more detailed test strategies or plans, not in the high-level policy.

Defect Prevention is a TMMi Level 5 process area. This process area focuses on identifying the root causes of defects and implementing preventive measures to avoid their recurrence. At TMMi Level 5, the goal is to optimize processes and move from defect detection to defect prevention.

Advanced Reviews and Test Measurement are Level 4 process areas, while Organizational Innovation and Deployment is part of CMMI, not TMMi.

TMMi References:

Defect Prevention is a key process area in TMMi Level 5, focusing on continuous process improvement and defect avoidance​​.

The Testing quadrants model is an Agile practice that helps establish a test strategy, as it provides a framework for categorising different types of tests (e.g., business-facing or technology-facing) and helps in balancing test activities. Within the TMMi Level 2 process area for Test Policy and Strategy, testing quadrants offer an Agile way to define and implement a test strategy that ensures comprehensive testing across various levels and types of testing activities.

Formal assessments, in contrast to informal ones, are conducted with more rigor, and the results can lead to an official certification of maturity level. A formal assessment report includes a validated maturity level rating, making it distinct from informal assessments, which are used only for indicative purposes and do not result in an official rating. Thus, only formal assessments provide an assessment report with a valid maturity level rating​​.

The TMMi model is designed to be versatile and applicable across all test levels (including static and dynamic testing) and all types of development methodologies, such as waterfall, Agile, and DevOps. It provides comprehensive coverage of the testing process, ensuring that all critical aspects of testing—such as lifecycle processes, techniques, infrastructure, and organization—are addressed.

TMMi is not limited to specific development methods or organizational sizes; it is lifecycle-independent and can be used effectively with various development approaches, making it widely applicable in both small and large organizations.

TMMi References:

TMMi covers all test levels, including both static testing (such as reviews) and dynamic testing at multiple stages, and is applicable across different software development lifecycles​​.

In the TMMi framework, a Specific Goal is unique to a particular process area and represents the essential outcomes that must be achieved for that process area. In contrast, a Generic Goal applies across multiple process areas and ensures that the processes are institutionalised, managed, and aligned with broader organisational objectives. Generic Goals help maintain consistency and effectiveness of processes across the organisation, while Specific Goals focus on the particular needs of an individual process area.

The specific practice "Testers review test basis documents" belongs to the Peer Reviews process 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.

This statement is false because the CMMI does not have defined levels specifically for testing maturity. The CMMI model is more general and focuses on 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.
