Scope Management

Scope Management means:

  1. Not letting others randomly expand the scope of the project without a structured change control system
  2. Constantly verifying the completion of all authorized work
  3. Ensure all changes are within the project charter
  4. Defining and controlling what is and is not included in the project
  5. Not allowing extra work or gold plating
