Waterfall

Key Characteristics of Waterfall Methodology

The Waterfall methodology in product management is characterized by its structured, linear approach:

1. Sequential phases: Requirements, Design, Implementation, Verification, and Maintenance
2. Rigid structure: Each phase must be completed before moving to the next
3. Comprehensive documentation: Detailed plans and specifications are created upfront
4. Limited flexibility: Changes are difficult and costly to implement once a phase is complete

When to Use Waterfall in Product Management

While Agile methodologies have gained popularity, Waterfall can still be effective in certain scenarios:

1. Projects with well-defined, stable requirements
2. Industries with strict regulatory compliance needs
3. Large-scale projects with multiple dependencies
4. When working with external vendors or contractors who require detailed specifications
