Building the Business Case

Turning a project idea into a compelling case for investment and approval

What Is a Business Case?

A business case explains why an organization should invest in a proposed initiative and what value that investment is expected to create. It answers a simple question: why should we do this?

It is different from a project charter. The business case justifies the investment — the problem, the value, the cost, the risk, and why the chosen option beats the alternatives. The charter comes after and authorizes delivery — scope, objectives, PM authority, timeline and success criteria.

The business case is approved first because it justifies why the project should exist. The charter follows, authorizing how it will be delivered.

Why It Matters to Project Managers

A PM who understands the business case manages more than delivery — they manage toward value. It helps PMs:

●      Understand why the project exists and prioritize requirements accordingly

●      Make better decisions and manage scope with purpose

●      Evaluate change requests and communicate confidently with sponsors

●      Measure whether value is actually delivered and challenge initiatives that no longer make sense
