• Marketing requirements document (MRD). This is the busi- ness or marketing team’s analysis of the world. The goal is to explain what business opportunities exist and how a project can exploit those opportunities. In some organizations, this is a reference document to help decision makers in their think- ing. In other organizations, it is the core of project definition and everything that follows derives strongly from it. MRDs help to define the “what” of a project. • Vision/scope document. A vision document encapsulates all available thinking about what a project might be into a sin- gle composition. If an MRD exists, a vision document should inherit and refer heavily to.
