TMMi-P_Syll2.1 Exam Dumps : TMMi Test Maturity Model Integration Professional (TMMi-P)

ISO/IEC 15504, which is known for its process assessment model, was not one of the sources used during the development of the TMMi model. The TMMi model was developed using inputs from sources such as the Capability Maturity Model Integration (CMMI), international testing standards (like those from ISO and IEEE), and industry testing best practices surveys. While the ISO/IEC 15504 model has relevance to general process assessments, it was not specifically referenced in the creation of the TMMi.

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​​.

This statement is not true regarding a staged model. In a staged 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 a continuous model 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.
