Targeting critical components is an optimal methodology for evolving and refining a project plan. It eliminates core uncertainties early in the project life-cycle.

changes in resources
changes in scope
changes in context arising from factors such as:
internal changes such as restructuring, reprioritization, and personnel changes
external changes such as emerging threats and opportunities
