To differentiate between program and project scopes, you can use several techniques. For instance, a program charter and a project charter should be used to document the purpose, objectives, scope, assumptions, constraints, risks, stakeholders, and authority of the program and the projects respectively. Additionally, a program scope statement and a project scope statement should be created to describe the scope of the program and the projects in more detail. This includes the scope description, deliverables, acceptance criteria, exclusions, and change control procedures. Moreover, a program work breakdown structure and a project work breakdown structure should be used to decompose the program and the project scopes into manageable components, levels, and work packages. Finally, a program scope management plan and a project scope management plan should outline the processes and tools for planning, defining, validating, and controlling the program and the project scopes throughout their life cycles.
