The Project Proposal Document (PPD) is often confused with a requirements document. Its purpose, however, is very different from a requirements document. As revealed above, a requirements document is technical and lengthy. Also, the audience for a requirements document includes technical professionals to construct the solution. On the other hand, a PPD is intended for non-technical decision makers, such as company owners, executives, managers, and other business professionals. Also, PPDs are written after SRS documents have been completed. PPDs provide summarized details of the proposed solution, feasibility overview, timeline, and costs based on the requirements gathering and domain research documented in the SRS.
The format of a PPD is reasonably standard, with some variation across project types and industries. Software PPDs provide a brief overview of the SRS document’s findings and include legally binding agreement language. The following example provides a basic framework for a PPD and some embedded notes regarding each section in the document.
