Business case approvals evaluate, review, and give authorisation to implement a proposed business plan or project. The business case approval checklist should be rigorous, involving input from a variety of sources, to explore the feasibility, benefits, costs, risks, and strategic value of the initiative. Approvals often gather input from key stakeholders, such as executives, sponsors, and subject matter experts. Stakeholders refer to their own experience and available historical data to review assumptions and estimates, then provide their own recommendations for further development or consideration before granting approval.
