My agency has a project over $1M, but we have not yet defined requirements or started project planning. What level of detail is necessary for the Schedule IV-B?
To be able to complete a IV-B, an agency must already have finalized the business case and project charter for the entire project, which includes all the business requirements, functional, non-functional, and technical, for the project. So if the requirements for the project are not yet clear and only at a high-level, it would be worthwhile to consider a separate project to first define the requirements and plan for the larger effort. A IV-B reflects the agency’s planning for a project, not its intention to plan later, if funded. If the $1M+ request is for documenting requirements needed to support a business case for a larger project, then the scope of the IV-B will only be for that phase of the project.
