According to BABOK, a business case provides a justification for a course of action based on the benefits to be realized by using the proposed solution, as compared to the cost, effort, and other considerations to acquire and live with that solution.

A business case consists preparing justification and the reasons why a certain project or concept should be undertaken.

This is done generally using formal, business documentation and covers factors such as the project’s cost, the way it will be implemented, the benefits and drawbacks, as well as any other associated savings that the business can stand to gain. 

A business case is used to:

  • define the needs,

  • determine the desired outcomes,

  • assess alternatives (each alternative should be assessed in terms of: Scope, Feasibility, Assumptions, Risks and constraints, Financial Analysis and Value Assessment,

  • recommend a solution.

A well-constructed business case allows you to convince your management team, clients, or stakeholders that the project you propound is a sound investment and will benefit the company.
