In which Practice Area does ensuring the availability of required participants fall under?

The practice of ensuring the availability of required participants falls under the Planning Practice Area in the context of CMMI. This is because Planning involves anticipating what resources, including participant availability, are necessary for successful execution of activities and processes.

In order to achieve project goals and milestones, effective planning requires identifying who needs to be involved and when they will be needed. This advance preparation helps ensure that the right expertise and stakeholders are present to contribute to the tasks at hand, thereby enhancing the likelihood of project success. The planning phase also includes establishing a timeline and allocating resources accordingly, which directly ties into participant availability.

Other practice areas, such as Implementation, Evaluation, and Control, focus on different aspects of projects and processes, such as executing the plan, assessing performance, and maintaining oversight, which do not primarily center around securing participant availability.
