A great idea isn’t enough to get a project started. To secure funding and support, you need a business case — a structured document that explains why the project matters, what it will deliver, and why it’s worth the investment.

But here’s the challenge: many business cases fail because they’re either too vague, too technical, or don’t clearly show the value. If you want your project to move forward, you need a business case that’s clear, compelling, and credible.

What is a Business Case?

A business case is the justification for undertaking a project, evaluated against the cost, risks, and expected benefits.

It answers three key questions:

  1. Why should we do this project?
  2. What benefits will it deliver?
  3. Is it worth the investment compared to other priorities?

Frameworks like PRINCE2 and PMBOK both treat the business case as central to project initiation and governance.

Key Elements of a Business Case

To get approval, your business case should cover these essentials:

  1. Executive Summary
    • A one-page overview that highlights the purpose, benefits, and recommendation.
  2. Problem/Opportunity Statement
    • Define the issue or opportunity driving the project.
  3. Options Analysis
    • Present different approaches (including “do nothing”).
    • Show why the recommended option is the best choice.
  4. Scope and Deliverables
    • Clarify what the project will (and won’t) deliver.
  5. Benefits Realisation
    • Describe tangible and intangible benefits.
    • Define how benefits will be measured and tracked.
  6. Cost Estimate and Funding
    • Provide clear, transparent costings.
    • Link to available budgets or funding sources.
  7. Risks and Dependencies
    • Identify major risks and mitigation strategies.
    • Show awareness of assumptions or external dependencies.
  8. Implementation Timeline
    • High-level schedule or roadmap.
  9. Governance and Accountability
    • Define roles (Sponsor, Project Manager, Steering Committee).
  10. Recommendation
  • A concise case for approval, supported by evidence.

Tips for Writing a Business Case That Gets Approved

  • Be clear, not technical. Executives want the why and so what, not technical jargon.
  • Focus on benefits. Show how the project supports strategic goals or community outcomes.
  • Present credible options. Even if only one is viable, demonstrating alternatives shows rigour.
  • Align with organisational strategy. Link your project to published strategic plans, policies, or objectives.
  • Keep it proportionate. A small IT upgrade doesn’t need a 50-page document; a hospital redevelopment does.

Real-World Example

A regional health service needed new staff accommodation.

  • Problem: Existing housing was unsafe and costly to maintain.
  • Options: Do nothing (unacceptable), refurbish old housing (expensive), or build new modular housing.
  • Recommended Option: Modular build, with lower long-term maintenance and safer living conditions.
  • Benefits: Improved staff retention, reduced maintenance costs, alignment with health workforce strategy.
  • Outcome: Funding approved because the case was clear, benefits-focused, and aligned to strategic goals.

Common Mistakes to Avoid

❌ Focusing too much on technical detail without showing value.

❌ Forgetting to include “do nothing” as an option.

❌ Overpromising benefits without defining how they’ll be measured.

❌ Ignoring risks and dependencies.

❌ Submitting a case that’s not aligned to organisational strategy.

Key Takeaways

  • A strong business case is the gateway to project approval.
  • Keep it clear, structured, and benefits-driven.
  • Show alignment to strategy, present credible options, and don’t ignore risks.
