TheAdvanced Reviewsprocess area, which is part ofTMMi Level 4, is concerned with measuring product quality early in the lifecycle. It aims to enhance thetest strategyandtest approachby aligningstatic testing(reviews and inspections) withdynamic testing(execution of test cases). The results and data from static testing are used to optimize the dynamic testing approach, making the overall testing process more efficient and effective.

Advanced Reviewsat TMMi Level 4 focuses on integrating static and dynamic testing approaches to optimize test strategy and product quality evaluation​​.

This statement is not true regarding a staged model. In astaged model, such as TMMi, organisations must follow a pre-defined path through maturity levels, and the process areas are organised in a fixed order that must be achieved sequentially. Each maturity level forms the foundation for the next, meaning that an organisation cannot achieve process areas at different capability levels independently, as is possible in acontinuousmodel like CMMI. The staged model is designed to ensure that each process area is fully implemented and institutionalised before progressing to the next maturity level.

To improve the quality of test cases and reduce defects in production, addressing the practice of "Identify and Prioritize Test Conditions" under Specific Goal 1 (SG 1) of the Test Design and Execution process area is essential. This specific practice involves identifying conditions based on an analysis of the test items and prioritising them based on risk and other factors. By improving the identification and prioritisation of test conditions, organisations can ensure that they focus on the most critical aspects of the system, thereby increasing the effectiveness of their testing efforts and reducing defects in production.

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.

CMMI version 2 recognises the importance of testing in software development and includes two dedicated practice areas:VerificationandValidation. These areas specifically addressthe processes required to ensure that a system or component meets its specified requirements and that the final product is fit for its intended use. While CMMI does not provide a testing-specific maturity model, these practice areas contribute to the overall quality management framework, and organisations adopting CMMI can leverage these processes to improve their testing practices. The TMMi framework complements CMMI by providing more detailed guidelines for testing.

As part of theProduct Quality Evaluationprocess area (4.2), the specific goal"Project Goals for Product Quality and their Priorities are Established"includes the practice ofidentifying product quality needs. This involves understanding and defining what quality means for the product, determining quality characteristics (such as reliability, usability, etc.), and establishing priorities for these characteristics based on project goals.

Other practices such asestablishing test process measuresandmeasuring product quality quantitativelycome later in the lifecycle or are part of other specific goals.

InProduct Quality EvaluationatTMMi Level 4, identifying product quality needs is critical for setting up measurable and prioritized goals for product quality​​.

The assessment described, where only interviews are used to collect evidence, aligns with aninformal TMMi assessment. Informal assessments are more flexible and do not require documentary evidence to corroborate interview data. They provide an indicative view of the organisation’s maturity but do not result in a formal maturity rating or certification​​.

Test Process Optimizationis the TMMi Level 5 process area specifically aimed at identifying new testing technologies and transitioning them into the organisation. This process area focuses on continuously improving the test process by evaluating and adopting new tools, methods, and technologies that can enhance testing efficiency and effectiveness. Test Process Optimization encourages organisations to stay ahead of industry developments and integrate innovative testing practices.

At TMMi Level 5, the process areasDefect Prevention,Quality Control, andTest Process Optimizationwork together to support continuous process improvement. Specifically:

Defect Preventionfocuses on identifying and analysing common causes of defects and proposing corrective actions to prevent them from recurring. This includes submitting test improvement proposals, which helpTest Process Optimizationfine-tune the testing process through these insights​​.

WhileQuality ControlsupportsDefect Preventionthrough statistical methods and analysis, the correct relationship betweenDefect PreventionandTest Process Optimizationinvolves submitting test improvement proposals to optimise the process.

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​​.
