What is Agile vs Waterfall
Agile and Waterfall are two distinct project management methodologies. Agile is iterative and flexible, focusing on delivering work in small increments. Waterfall is linear and sequential, with each phase completed before the next begins.
Core framework
Agile frameworks like Scrum and Kanban emphasize collaboration, customer feedback, and small, rapid releases. Waterfall follows a strict sequence: requirements, design, implementation, verification, and maintenance.
How Agile appears in the 2026 PMP exam
Approximately 60% of the 2026 PMP exam uses agile or hybrid approaches, distributed across all three domains. The Process domain (41% of the exam) carries the largest volume of agile-related questions.
When to choose pure Agile vs hybrid
Choose pure Agile for projects with unclear requirements and high change potential. Hybrid approaches work well when some phases benefit from Waterfall’s structure while others need Agile’s flexibility.
Common anti-patterns
Common Agile anti-patterns include skipping retrospectives, ignoring team velocity, and treating sprints as mini-Waterfalls. Waterfall anti-patterns include rigidly following the plan despite changing needs.
Metrics that matter
Agile teams track velocity, burn-down charts, and cycle time. Waterfall teams focus on phase completion percentages, critical path, and earned value management.
