Understanding the distinction between Agile and Waterfall methodologies is critical for choosing the right approach for project execution. Agile promotes flexibility and collaboration, while Waterfall follows a linear, structured path.

18_2: Definitions

18_6: When to Use

• Fast-moving or startup environments

• Need for frequent releases

Waterfall:

• Projects with fixed, well-understood scope

• Regulatory or compliance-heavy projects

18_8: Conclusion

Agile is well-suited for adaptive, feedback-driven environments with evolving needs, commonly supported by tools like Jira, Confluence, and Kanban. Waterfall, on the other hand, provides a predictable path for well-scoped projects. Choosing between them depends on the project type, risk appetite, customer engagement, and team maturity.
