Which process is focused on managing the entire life cycle of a system?

The process that is focused on managing the entire life cycle of a system is Life Cycle Model Management. This process encompasses the strategies, methodologies, and practices necessary for overseeing the phases of a system's life cycle—from conception and development to deployment, operation, maintenance, and eventual retirement.

Life Cycle Model Management ensures that the system is designed, developed, and maintained through a disciplined approach, incorporating feedback and continuous improvement at each stage. It also involves considerations for cost, schedule, performance, and risk management throughout the life cycle, aligning with systems engineering principles.

This approach allows organizations to systematically manage changes and track progress, ensuring that systems meet their intended purpose effectively and efficiently over time.
