True or False: Within a Practice Area, each evolutionary level builds on the previous levels and adds new functionality.

The statement is true because within a Practice Area of the Capability Maturity Model Integration (CMMI), each evolutionary level indeed builds upon the foundation established by previous levels and introduces additional capabilities or functionality.

CMMI is structured in a way that encourages organizations to progress through incremental stages of maturity. As an organization moves from one level to a higher level, it enhances its processes and integrates more sophisticated practices that were not present at earlier levels. This progressive nature ensures that foundational practices are solidified before new ones are added, allowing for a more systematic and manageable evolution of organizational processes.

Understanding this concept is critical for organizations striving to improve their processes and achieve a higher maturity level. It underscores the importance of establishing a strong base before attempting to incorporate more complex practices, ensuring sustainability and effectiveness in process improvement efforts.
