What role is responsible for ensuring the process is implemented across all lifecycle stages as intended?

The Process Manager holds a crucial role in ensuring that a specific process is effectively implemented across all lifecycle stages of service management as intended. This role encompasses the responsibility for the design, implementation, and improvement of the processes within their scope. The Process Manager ensures that the processes are not only followed but are also integrated into the broader ITIL framework, remaining consistent and aligned with organizational goals throughout the service lifecycle.

In particular, the Process Manager's responsibilities include monitoring process performance, ensuring compliance with the defined process, and facilitating necessary updates to process documentation based on feedback and performance metrics. This role acts as a bridge among different stages of the service lifecycle, guaranteeing that procedures evolve in response to changing business needs and that all teams are aligned in their execution.

While other roles mentioned, such as Service Owner and Service Designer, have important functions within service management, they focus more on service delivery and design aspects rather than the overarching management and consistency of processes across all lifecycle stages. The Process Practitioner, on the other hand, is typically more involved in the daily execution of the process rather than its oversight and management across the entire service lifecycle.
