In accordance with the PMBOK® Guide, Progressive Elaboration is the iterative process of increasing the level of detail in a project management plan as greater amounts of information and more accurate estimates become available.
This concept acknowledges that it is rarely possible to define every detail of a project at its initiation. Instead, the project management plan is developed in broad strokes early on and then refined and made more specific as the project team gains a better understanding of the objectives, deliverables, and constraints.
Relationship to Rolling Wave Planning: Progressive elaboration is the broader concept that encompasses Rolling Wave Planning, where near-term work is planned in detail while future work is planned at a high level.
Purpose: It allows a project management team to manage to a greater level of detail as the project evolves, ensuring the plan remains realistic and aligned with current project realities.
Distinction from Scope Creep: Unlike scope creep (uncontrolled changes), progressive elaboration is a controlled, intentional process of refining the existing authorized scope.
Analysis of Distractors:
A. Continuous improvement: Also known as Kaizen, this refers to an ongoing effort to improve products, services, or processes over time. While it is an iterative mindset, it is not the specific term for refining project plan details.
B. Predictive planning: This refers to a project life cycle (Waterfall) where the scope, time, and cost are determined as early as possible. While predictive projects use progressive elaboration, " predictive planning " is not the name of the iterative refinement process itself.
D. Quality assurance: This is the process of auditing the quality requirements and the results from quality control measurements to ensure that appropriate quality standards and operational definitions are used. It does not relate to the detail level of the management plan.
