Free Business Case Template

This Business Case template is used by business analysts to justify whether a project should go ahead at all — before any funding or resourcing is committed, not after.

What Is a Business Case?

A Business Case sets out the problem or opportunity driving a proposed project, the options available to address it, a recommended option, and the costs, benefits, and risks of proceeding. It’s written for a sponsor to approve or reject before any budget or team is committed — its job is to make the “should we do this” decision defensible, not to describe how the work will be delivered once approved.

What Should a Business Case Include?

• Problem or opportunity statement — what’s driving the need for change, in business terms, not solution terms
• Options considered — including “do nothing,” so the cost of inaction is visible alongside the cost of acting
• Recommended option — with the reasoning for why it beats the alternatives
• Costs and benefits — for the recommended option and, ideally, the alternatives too
• Return on investment / payback period — how long before benefits outweigh cost
• Key risks and assumptions — what could undermine the projected benefits
• Sponsor and approval — who is accountable for the decision and the outcome

Business Case vs Project Charter — What’s the Difference?

A Business Case answers whether a project should happen at all — it compares options and their costs and benefits, and it’s approved before funding is committed. A Project Charter comes after: once the Business Case is approved, the Charter formally authorises the project, names the project manager, and defines scope and objectives at a high level so delivery can start. The Business Case makes the decision; the Charter executes on it.

Common Mistakes When Writing a Business Case

• Only one option presented. A Business Case with a single option dressed as analysis isn’t a real decision document — it’s a justification written after the choice was already made.
• Benefits without numbers. “Improved efficiency” isn’t a benefit a sponsor can hold anyone accountable for later — quantify it, even roughly, so it can be checked after go-live.
• No accountable sponsor. A Business Case approved by committee with no single named owner tends to have nobody who feels responsible when benefits don’t materialise.
• Skipping “do nothing.” Without a do-nothing baseline, there’s no way to judge whether the proposed option is actually worth the cost and disruption of change.

What’s Included in This Template

• Pre-structured sections with guidance notes
• Worked examples from real BA projects
• Guidance for Agile, waterfall, and hybrid approaches
• Easy to adapt to your organisation’s standards

How to Use This Template

Build the Business Case before any solution design work starts — solutioning too early tends to anchor the whole document around one option, undermining the comparison a sponsor actually needs to see. Each section has guidance notes explaining what to include and why — based on real BA practice, not textbook theory. Remove sections that don’t apply and add organisation-specific fields.

Once a Business Case is approved, the next document is usually a Project Charter — it formally hands the approved option to a named project manager with the authority to start delivery.

Why Requirements Templates Matter

Consistent documentation is one of the most underrated BA skills. A well-structured document:

• Sets clear expectations from day one
• Reduces “we didn’t know that was in scope” conversations
• Creates an audit trail for decisions and changes
• Speeds up new team member onboarding
• Builds your credibility as a professional BA

Frequently Asked Questions

What is a Business Case used for?

It justifies whether a project should go ahead, comparing options and their costs and benefits, and is approved before any funding is committed.

What is the difference between a Business Case and a Project Charter?

The Business Case decides whether to proceed. The Project Charter, created after approval, formally authorises the project and names the project manager to start delivery.

Does a Business Case need more than one option?

Yes — a credible Business Case compares the recommended option against doing nothing and at least one genuine alternative, not just one option dressed as analysis.
