Which aspect is central to the management case of a business proposal?

The central aspect of the management case in a business proposal is the delivery capability of the preferred option. This is crucial because it directly addresses whether the proposed solution can be successfully implemented within the constraints of time, resources, and budget. The management case focuses on how to deliver the project, considering factors such as management structures, responsibilities, governance, and plans for communication and stakeholder engagement. By ensuring that the delivery capability is adequately assessed, organizations increase their chances of achieving project objectives and realizing benefits.

While the other aspects mentioned are important, they serve as supportive elements rather than the core focus of the management case. For instance, the technical feasibility is vital but falls under the business case or financial case, and alignment with strategic goals is essential for justification at a higher level but does not detail how to execute the project effectively. Similarly, the long-term impact on stakeholders is a consideration for sustainability and accountability but is not the primary focus of the management case.
