Which is one of the five aspects of service design?

Management information systems and tools is one of the five formally defined aspects of service design in ITIL, covering the systems and repositories needed to manage and support services across the lifecycle, including the Service Portfolio. The remaining four aspects are service solutions, technology and management architectures, processes, and measurement methods and metrics.

Risk analysis and management is an activity performed across multiple lifecycle stages and within service design, but it is not listed as one of the five specific aspects of service design.

Management policy for business case creation is not one of the five aspects of service design - business cases are a governance artifact used broadly across the lifecycle, not a design dimension.

Corporate governance and policy is an organizational concern that shapes all lifecycle stages but is not one of the five discrete aspects defined within service design.
