The business case is a process of critically examining the opportunities, alternatives, project stages and financial investment to make a recommendation for the best course of action that will create business value.
The purpose of a business case is to make a compelling argument for why the project should be approved and funded. It is used to persuade decision-makers to invest resources in the project, and to provide a roadmap for the project team to follow.
The business case should be based on a thorough analysis of the potential costs, benefits, risks, and opportunities associated with the project. It should also outline the key assumptions and constraints that will impact the project and describe how the project will be executed and managed.
