What describes the necessary infrastructure to ensure sustainable process implementation in CMMI?

The term that describes the necessary infrastructure to ensure sustainable process implementation in CMMI is Implementation Infrastructure. This concept comprises the resources, tools, processes, and organizational structures necessary for effectively implementing and maintaining improvements in processes aligned with CMMI.

Implementation Infrastructure encompasses multiple aspects, including governance structures, training programs, and communication channels within an organization. It facilitates the adoption of processes by providing the framework needed to support ongoing process management and improvement.

The other choices, while related to organizational processes, do not capture the specific focus on the infrastructure required for sustainable implementation. For example, an Organizational Framework is broader and deals with the overall structure and culture of the organization that supports different initiatives, but it doesn't specifically emphasize the infrastructure required for process implementation. Similarly, Process Architecture focuses on defining the processes themselves and their interrelationships rather than on the sustaining aspects of implementation. System Design refers more to the technical systems in place for operations rather than the holistic infrastructure for supporting process sustainability in the context of CMMI.
