Definition
Predictive, plan based methodologies are project management approaches where all project requirements are determined upfront and a detailed plan is created before execution begins. These methods emphasize sequential phases, with each phase needing completion before the next can start. This structured approach aims to control scope, schedule, and cost by minimizing changes after the project is underway. It is particularly effective for projects with well-defined goals and stable requirements, ensuring a predictable outcome. Unlike agile methods that embrace change, predictive approaches are best when the end product is clearly understood from the outset. This concept is frequently tested in project management certifications like PMP and CAPM.
