A thorough project definition is the first line of defense against scope creep.
Many projects are doomed to failure due to poor definition. It’s the leading cause of scope creep. Since the plan reflects the work, resources, budget and time necessary to satisfy the scope, an accurate, realistic project definition is of critical importance. There are seven essential elements that need to be included in the project definition:
__ The business problem and the solution.
__ The benefits of completing the project (the business case).
__ A concise (25-30 word) definition of the project schedule, scope and budget.
__ A list of the major deliverables (which, when delivered, completely satisfy the scope of the project), including what is in scope and out of scope for each.
__ A priority matrix that summarizes the sponsor’s priorities for the schedule, scope and budget parameters that define the project.
__ Target customers for the project deliverables.
__ Project dependencies (committed dates and commitments to/from other projects).
These project definition components do not exclude other possibilities that can enhance understanding of the projects such as :
__ A milestone schedule that documents interim deliverables requested by the sponsor.
__ An impact statement that identifies what can or will be impacted by the project.
