- Scope creep and feature creep are two unfavorable outcomes that may result from this. To make the distinction between the two ideas evident, explain them. What is the primary reason behind these two issues? What happens in this project's worst-case scenario if these two unfavorable circumstances arise?arrow_forwardProject 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."

(2) Outline the problem(s) that the project was initiated to solve or the opportunity it exploited. (3) Describe the technique or method used to select the project. (4) Identify and describe at least five (5) characteristics that make this endeavour a project. (5) Identify the project developmental approach used for the project.
