Project Scope Management Khan, (2006) (see below) states that, "Managing the scope of a project is the most important function of a project manager ... Effective scope management of a project also ensures the success of key completion areas, including time, cost, and quality. Project scope management can be further subdivided into its components which include: project initiation, scope planning, scope definition, scope verification, and scope change control." Based on your Integrated Project: Select two of the subdivisions above and discuss the primary issues that could arise from the process. Your response should begin with a definition of the selected subdivision before detailing the selected process
