“A well-defined Scope of Work document is an essential pre-requisite for developing a WBS.” Using examples, discuss why the above statement is true.

One of the thorny issues in managing project scope is “Scope Creep.” While a well-defined scope document can greatly reduce the potential for scope creep, it cannot completely eliminate it. If you agree with the above statement, given below are some follow-up questions. Given that a certain degree of scope creep is inevitable in any project, how can a PM minimize the potential disruptions that a scope creep can cause? Should the PM even after the development of a fully agreed upon scope document, allow for changes in scope within a reasonable time frame with an absolute deadline? If your answer is “yes”, how would you define that REASONABLE TIME FRAME?
