What is a business case used for in project planning?

A business case plays a crucial role in project planning as it is a comprehensive document that articulates the rationale for initiating a project. The primary purpose of a business case is to justify the project by detailing its potential benefits, costs involved, and associated risks. This justification is vital, as it helps stakeholders understand the value proposition of the project and provides a framework for decision-making.

By outlining these elements, the business case facilitates conversations about resource allocation, prioritization, and alignment with organizational strategy. It allows decision-makers to weigh the expected returns against the costs and risks, ensuring that investments are made in projects that provide value and are achievable within the organization's capacity.
