Сравнение каскадного подхода (Waterfall) и гибкого подхода (Agile)
Key Distinction
Waterfall and Agile are implemented in many different ways on many different projects, and some projects may use aspects of each. The chart below briefly describes and compares Waterfall and Agile approaches. You can use it as a quick reference tool, but be aware that in practice, the differences between these two approaches may not always be clearly defined.
Waterfall vs Agile Comparison Table
| Aspect | Waterfall | Agile |
|---|---|---|
| Project Manager’s Role | Project manager serves as an active leader by prioritizing and assigning tasks to team members | Scrum Master acts primarily as a facilitator, removing any barriers the team faces. Team shares more responsibility in managing their own work |

| Schedule | Follows a mostly linear path through initiating, planning, executing, and closing phases | Time is organized into Sprints. Each Sprint has defined duration with planned deliverables |
| Cost | Costs are controlled by careful upfront estimation and close monitoring throughout | Costs and schedule could change with each iteration |
| Quality | Project manager defines quality criteria and plans at project start | Team solicits ongoing stakeholder input and implements regular improvements |
| Communication | Project manager regularly communicates progress on milestones to stakeholders | Team maintains consistent communication between users and project team |
