What are the advantages and disadvantages of the waterfall development method in software design?

The Waterfall development method is a sequential approach to software creation, where each stage (requirements analysis, design, implementation, testing, deployment) is performed one after the other.

Advantages:

• Clear structure and sequence of stages.
• Easy to manage and control the process.
• Well-suited for projects with well-defined requirements.

Disadvantages:

• Difficult to make changes after the requirements stage is completed.
• Errors are detected late, as testing occurs after implementation.
• Limited flexibility, which makes it difficult to adapt to changing requirements.

Thus, Waterfall is well-suited for projects with fixed requirements but less effective in conditions of uncertainty and rapid change.
