What key aspect should a service business case ideally cover?

A service business case should ideally cover all areas of a full service from proposal to resources because it provides a comprehensive view necessary for effective decision-making. This includes not only financial considerations like costs, risks, and expected benefits, but also operational aspects, stakeholder needs, service design, implementation strategies, and resource requirements.

By addressing a holistic range of factors, the business case helps ensure that all relevant elements are considered, enabling stakeholders to understand the full impact and value of the proposed service. This comprehensive approach aids in aligning the service with organizational goals and stakeholder expectations, fostering better outcomes and facilitating informed decision-making throughout the service lifecycle.

Focusing solely on costs, risks, or expected benefits, as indicated in other options, limits the understanding of the service's potential and the necessary steps for its implementation and success.
