In CMMI V2.0, predefined model views represent specific ways of applying the CMMI framework to focus on particular areas of interest or practice within an organization. The "Service" model view is designed to address the unique challenges and processes associated with service delivery, emphasizing capabilities like service management, service delivery, and performance management in a service-oriented context. This model view helps organizations improve their service-related processes, ensuring that they can effectively meet customer needs and expectations.
The other options, while important aspects of organizational processes, do not specifically represent predefined model views in CMMI V2.0. Project Management and Risk Management are disciplines that may be part of broader model views or practices, but they do not have a standalone, predefined view in the same way that the "Service" model does. Quality Assurance is similarly critical but does not constitute a separate model view. Thus, the "Service" model view is the correct answer as it is specifically defined within the CMMI framework.
