Managing project scope is essential to ensure that the project includes all the work required, and only the work required, in order to meet the project objectives. Requirements collection and scope definition are the foundations of scope management. Requirements specify the project’s product or service and shape the project scope, which in turn defines what must be done to fulfill the requirements and complete the project according to the specification. This chapter discusses scope management in localization projects. Drawing on the Project Management Institute’s A Guide to the Project Management Body of Knowledge (PMBOK® Guide), the chapter examines the five processes that comprise scope management: requirements collection, scope definition, work breakdown structure creation, scope verification and scope control. It then discusses the application of these processes in localization projects, focusing primarily on requirements collection.
