A Guide to the Project Management Body of Knowledge (PMBOK® Guide), Third Edition

Project Scope Management includes the processes required to ensure that the project includes all the work required, and only the work required, to complete the project successfully [5]. Project scope management is primarily concerned with defining and controlling what is and is not included in the project. Figure 5-1 provides an overview of the Project Scope Management processes, and Figure 5-2 provides a process flow diagram of those processes and their inputs, outputs, and other related Knowledge Area processes.
5.1 Scope Planning creating a project scope management plan that documents how the project scope will be defined, verified, controlled, and how the work breakdown structure (WBS) will be created and defined.
5.2 Scope Definition developing a detailed project scope statement as the basis for future project decisions.
5.3 Create WBS subdividing the major project deliverables and project work into smaller, more manageable components.
5.4 Scope Verification formalizing acceptance of the completed project deliverables.
5.5 Scope Control controlling changes to the project scope.
These processes interact with each other and with processes in the other Knowledge Areas as well. Each process can involve effort from one or more persons or groups of persons, based on the needs of the project. Each process occurs at least once in every project and occurs in one or more project phases, if the project is divided into phases.
