What is a fundamental requirement for effective capability development in CMMI?

In the context of CMMI (Capability Maturity Model Integration), a fundamental requirement for effective capability development is the establishment of defined processes for each Capability Area. This emphasis on defined processes ensures that organizations have a structured approach to delivering their products and services, which enhances consistency, efficiency, and quality.

Defined processes allow for clear roles, responsibilities, and expectations within an organization, which facilitate better planning and execution of projects. By having well-articulated processes in place, teams are better equipped to identify strengths and weaknesses within their operations, leading to targeted improvements and more effective capability development.

While availability of skilled personnel, regular training sessions, and access to tools and technology are also important components that contribute to an organization's capability, they are not fundamental requirements in the same way that defined processes are. Without established processes, skilled personnel may not know how to effectively apply their knowledge, training might not align with organizational goals, and tools may not be utilized to their full potential. Therefore, the emphasis on having defined processes for each Capability Area serves as the backbone of effective capability development in CMMI.
