When should you use Waterfall methodology and Agile methodology?

You should use waterfall methodology:

1. When there is a clear picture of what the final product should be.

2. When clients won’t have the ability to change the scope of the project once it has begun.

3. When definition, not speed, is key to success.

Agile methodology:

1. When rapid production is more important than the quality of the product.

2. When clients will be able to chance the scope of the project.

3. When there isn’t a clear picture of what the final product should look like.

4. When you have skilled developers who are adaptable and able to think independently.

5. When the product is intended for an industry with rapidly changing standards.

 

Both the Agile and waterfall methodologies have their strengths and weaknesses. The key to deciding which is right for you comes down to the context of the project. Is it going to be changing rapidly? If so, choose Agile. Do you know exactly what you need? Good. Then maybe waterfall is the better option. Or better yet? Consider taking aspects of both methodologies and combining them in order to make the best possible software development process for your project.
