Predictive Approach
A plan-driven, sequential approach where scope, schedule, and cost are defined early.
The predictive approach, often called waterfall, organizes work into sequential life-cycle phases where each phase produces deliverables that feed the next. Scope, schedule, and cost baselines are defined early and governed through formal integrated change control, so any deviation must go through an approved change request before work adjusts. Note that initiating, planning, executing, monitoring and controlling, and closing are the five process groups that recur within phases, not a strict linear sequence—monitoring and controlling runs continuously. The exam trigger for choosing predictive is low uncertainty with stable, fully definable requirements up front; adaptive (agile) methods suit high-uncertainty, evolving-scope work.
