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 Reference:

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​.

During the Diagnosing phase of a test improvement cycle, in addition to conducting an assessment to

determine the current maturity status, the activity of developing recommendations is also

performed. These recommendations provide guidance on what actions should be taken to achieve

the desired improvements. The assessment helps establish the organisation's current state, and the

recommendations serve as a roadmap for moving forward.

Reference:

"The Diagnosing phase includes the activities of characterizing the current state and developing

recommendations for improvement" .

The specific practice "Establish the Organization’s Test Process Database" is found within the Test

Lifecycle and Integration process area, which is part of TMMi Level 3. This process area aims to

establish standardized test processes across the organization, including maintaining a test process

database that holds process-related information and data for reuse and continuous improvement.

TMMi Reference:

The Test Lifecycle and Integration process area is responsible for establishing and maintaining

organizational test process assets, including the test process database​​.

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.

Reference:

"Specific practice is described as an activity important for achieving the associated specific goal,

making it an expected component"​.

The specific practice "Define product risk categories and parameters" is part of the Test Policy and

Strategy process 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 Reference:

The practice of defining product risk categories is directly linked to the Test Policy and Strategy

process area at TMMi Level 2, where risk-based testing approaches are established​​.

The statement that Specific Goal 1 of the Test Measurement (4.1) process area covers the

communication of test measurement results after analysis is FALSE. Specific Goal 1 focuses on

aligning test measurement and analysis activities, which involves setting measurement objectives,

specifying the measures to be taken, and establishing procedures for data collection, storage, and

analysis. However, the communication of results comes under Specific Goal 2, which deals with the

analysis and reporting of test measurement results.

TMMi Reference:

Test Measurement at TMMi Level 4 includes defining measures, data collection, and storage as part

of aligning test measurement and analysis activities, while communicating results is part of a

different goal​​.

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 Reference:

The Test Lifecycle and Integration process area at TMMi Level 3 addresses the need for

comprehensive and integrated test planning across all test levels​​.

Informal assessments, as described in the TMMi framework, are often quicker and cheaper as they

do not require the extensive corroboration of evidence that formal assessments do. One key

characteristic of informal assessments is that they may rely solely on interviews, without using other

forms of corroboration such as documentation reviews or observations. These informal assessments

provide an indicative view of the organization's maturity level but do not result in formal certification​

The communication skills of testers is 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 to effectively interact with stakeholders. These

skills are typically developed through other training or team-building initiatives, not through process

improvements outlined by TMMi.

Reference:

"The TMMi model focuses on improving testing processes and management but does not specifically

target the development of communication skills" .

For the Test Policy and Strategy process area, with a 40% achievement, the appropriate compliance

rating is "Partly achieved". According to TMMi, a process area is rated as "partly achieved" when a

portion of the practices has been implemented, but significant improvements are still needed​​​.
