How do waterfall and agile planning differ?

Waterfall and Agile are two different approaches to project planning and management.

Waterfall (cascade method):

• Linear and sequential process.
• All stages (analysis, design, development, testing, deployment) are performed one after another.
• Planning occurs at the beginning of the project, and it is difficult to make changes later.
• Suitable for projects with clear and stable requirements.

Agile:

• Iterative and flexible approach.
• The project is divided into short cycles (sprints), each producing a working product.
• Planning and priorities are regularly reviewed.
• Allows quick adaptation to changes and feedback.

Thus, the main difference lies in flexibility and approach to changes: Waterfall fixes the plan in advance, while Agile continuously adapts.
