Which practice within CMMI ensures that processes are regularly improved and maintained?

The practice that ensures processes are regularly improved and maintained is primarily focused on establishing a solid foundation for process implementation, monitoring, and optimization. This practice emphasizes the importance of creating an effective implementation infrastructure that supports ongoing improvements in organizational processes.

Having a robust implementation infrastructure means that an organization is well-equipped to continuously advance its operational capabilities. It facilitates the establishment of feedback mechanisms, metrics collection, and data analysis, all of which are instrumental in identifying areas for enhancement. Moreover, this practice encourages a culture of continuous improvement, ensuring that organizations routinely assess their processes and make necessary adjustments to enhance performance and effectiveness.

In contrast, the other practices listed focus on different aspects of management. Configuration Management deals with the control and maintenance of product and service configurations; Improving Performance is more focused on measuring and enhancing specific performance metrics; Process Asset Development pertains to capturing and organizing process assets but does not inherently ensure ongoing improvements. Therefore, the practice that centers on creating a supportive environment for regular process improvement and maintenance aligns best with the function of implementation infrastructure.
