This artifact provides the necessary information from a business standpoint to determine whether or not this project is worth investing in. For a commercial software product, the Business Case should include a set of assumptions about the project and the order of magnitude return on investment (ROI) if those assumptions are true. For example, the ROI will be a magnitude of five if completed in one year, two if completed in two years, and a negative number after that. These assumptions are checked again at the end of the Elaboration phase, when the scope and plan are defined with more accuracy. |
