Waterfall
What is the Waterfall methodology in product management?
The Waterfall methodology in product management is a linear, sequential approach to product development where each phase must be completed before the next one begins. It follows a strict, step-by-step process from conception to delivery, with little room for changes once a phase is completed.
Synonyms: Sequential development, Linear product development, Traditional project management, Waterfall model, Waterfall approach
Key Characteristics of Waterfall Methodology
The Waterfall methodology in product management is characterized by its structured, linear approach:
- Sequential phases: Requirements, Design, Implementation, Verification, and Maintenance
- Rigid structure: Each phase must be completed before moving to the next
- Comprehensive documentation: Detailed plans and specifications are created upfront
- 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:
- Projects with well-defined, stable requirements
- Industries with strict regulatory compliance needs
- Large-scale projects with multiple dependencies
- When working with external vendors or contractors who require detailed specifications
