A compelling business case outlines the expected benefits of this investment decision.
The business case document should explain the following:
The investment decision.
Key objectives for the project.
The business needs.
The project definition. Provide necessary background and supporting information to put the investment into context.
Describe how the investment aligns with the organization's strategic business plan.
Describe the different options explored and why you are recommending this option or solution.
Provide a robust budget, an estimate of the whole-of-life costs of the investment and its financial benefits and the projected financial statements.
The business benefits include an estimate of the non-financial benefits.
How to make sustainability core to the recommendation and outcomes.
Describe the implementation approach, including timelines, resources, the procurement strategy, project governance, and how to embed sustainability practices.
Rigorously assess the inherent risks, different scenarios and sensitivities, including how they are likely to affect the investment and outline strategies for mitigating them.
Convey the level of uncertainty surrounding the proposal.
Provide options for the board and management to consider in reaching a decision.
In large organizations, there are often guidelines defined for the business case writer to help them write what's called an "investment appraisal" for their business case.
Any leadership or professional role may assume responsibility for producing and writing the business case if the decision-makers trust that individual. Thus, executives, business leaders, project managers, business analysts, internal and external consultants, and IT managers are included.
The project sponsor or project manager may lead the development of the business case.
The goals of the recommended project, the project customers, users and stakeholders, and the business outcomes and benefits are more important than technology, domain knowledge, or deliverables in a robust business case.
The business case lead or writer focuses on evaluating, analyzing, quantifying and delivering the business value. Poor project results can result from insufficient attention to the details of a business case and accompanying analysis.
