A business case is a document that clearly identifies the reasoning for initiating a project to justify the resources required. It is written to justify the resources required for the project (money or effort) and align the project objectives to the business needs. It also includes the costs, benefits, and risks of the proposed solution, and compares it with alternative options1. A business case is an important input for the project initiation and approval process, as it helps the decision makers to assess the value and feasibility of the project2.
To write a business case, you need four main inputs: feasibility study, assumptions and constraints, business need, and solution options3. A feasibility study is an analysis that evaluates the technical, economic, social, and environmental aspects of the project, and determines whether it is viable and worth pursuing4. Assumptions and constraints are factors that affect the project scope, cost, schedule, and quality, and that need to be identified and documented in the business case. Assumptions are things that are believed to be true or certain, while constraints are things that limit or restrict the project5. Business need is the problem or opportunity that the project aims to address, and that aligns with the strategic goals and vision of the organization. Solution options are the different ways of solving the business need, and their respective costs, benefits, and risks.
Stakeholder concerns are not an input for writing a business case, but rather an output of stakeholder analysis. Stakeholder analysis is a process of identifying and prioritizing the people or groups who have an interest or influence in the project, and understanding their needs, expectations, and perspectives. Stakeholder concerns are the issues or challenges that the stakeholders face or anticipate in relation to the project, and that need to be addressed or resolved. Stakeholder concerns are important for defining the requirements, managing the communication, and ensuring the stakeholder satisfaction, but they are not directly used for writing the business case.
