Waterfall versus Agile project management

The key differences between Waterfall and Agile project management methodologies can be summarized as follows:

Waterfall Project Management:

  1. Sequential Process:
    • Follows a linear, phase-based approach where each phase must be completed before the next one begins (e.g., Requirements, Design, Implementation, Testing, Deployment, Maintenance).
  2. Fixed Requirements:
    • Requirements are defined upfront and expected to remain unchanged. Changes are difficult to implement once the project progresses.
  3. Documentation:
    • Extensive documentation is created at each stage to ensure clarity and guide the project lifecycle.
  4. Predictability:
    • Offers high predictability in terms of timelines, costs, and deliverables as everything is planned in advance.
  5. Best Suited For:

Agile Project Management:

  1. Iterative Process:
    • Follows an iterative and incremental approach, breaking the project into small cycles called sprints (typically 2-4 weeks long). Each sprint involves planning, executing, and evaluating.
  2. Flexible Requirements:
    • Requirements are expected to evolve throughout the project based on stakeholder feedback and changing circumstances.
  3. Collaboration and Communication:
    • Emphasizes close collaboration among cross-functional teams, including regular communication through daily stand-ups, sprint reviews, and retrospectives.
  4. Minimal Documentation:
    • Focuses on delivering working software over comprehensive documentation, with necessary documentation created on an as-needed basis.
  5. Customer Involvement:
    • Customers and stakeholders are actively involved throughout the project, providing feedback and shaping the product with frequent deliveries of functional increments.
  6. Best Suited For:

Summary

  • Waterfall is structured, predictable, and best for projects with clear, unchanging requirements.
  • Agile is flexible, adaptive, and ideal for projects that require frequent iterations and feedback.
