CAPM Practice: Demonstrate an understanding of the various project life cycles and processes

The key distinction is when and how requirements and plans are developed. Predictive approaches plan extensively upfront with detailed requirements, while adaptive approaches embrace change and develop requirements iteratively throughout the project lifecycle.

**Why not B:** Both predictive and adaptive approaches involve stakeholders. Predictive approaches engage stakeholders through formal reviews and approvals, while adaptive approaches involve them more continuously. The distinction is about how requirements and plans are developed, not stakeholder involvement levels.

**Why not C:** Neither approach is inherently more cost-effective. The cost-effectiveness depends on the project context, requirements stability, and organizational factors. Predictive approaches can be very efficient for well-understood work, while adaptive approaches reduce waste when requirements are uncertain.

**Why not D:** Both approaches can be used across industries. Predictive approaches are common in construction but also used in software. Adaptive approaches originated in software but are applied to manufacturing, marketing, and other fields. The distinction is about planning methodology, not industry applicability.
