Answer
Waterfall follows sequential phases with fixed requirements, while Agile uses iterative cycles with flexible adaptation to changes.
Agile and Waterfall represent two fundamentally different approaches to project management, each suited to different types of projects and environments.
Waterfall Methodology:
- Sequential phases: requirements, design, implementation, testing, deployment
- Detailed upfront planning with fixed scope and timeline
- Limited flexibility for changes once development begins
- Extensive documentation and formal approval processes
- Best for projects with well-defined, stable requirements
Agile Methodology:
- Iterative development in short cycles (sprints)
- Continuous collaboration and feedback
- Embraces change and adapts to evolving requirements
- Working software/deliverables over comprehensive documentation
- Regular retrospectives for continuous improvement
Key Differences:
- Flexibility: Agile adapts to change; Waterfall resists it
- Risk: Waterfall has higher risk of late discovery of issues
- Customer involvement: Agile requires continuous engagement; Waterfall minimal after initial requirements
- Timeline: Agile delivers value incrementally; Waterfall at project end
Pierre Beerens from B&B Real Estate suggests choosing based on project complexity, requirement stability, and stakeholder availability. Hybrid approaches combining both methodologies are increasingly popular.
