What are the differences between iterative and waterfall methodologies?

What are the differences between iterative and waterfall methodologies?

The waterfall methodology is a linear approach where each phase must be completed before the next begins. Iterative methodology, on the other hand, allows for repeated cycles of development, enabling teams to refine and improve the product continuously.

Can you give me an example of when to use each methodology?

Sure! Waterfall is often used in projects with well-defined requirements, like construction. Iterative is better for software development where requirements may evolve.

What are the advantages of using an iterative approach?

Iterative approaches allow for flexibility, quicker feedback, and the ability to adapt to changes, which can lead to a better final product.

Are there any disadvantages to the iterative methodology?

Yes, it can lead to scope creep if not managed properly, and it may require more resources and time for continuous testing and feedback.

Which methodology is more popular in tech projects?

Currently, iterative methodologies, especially Agile, are more popular in tech projects due to their adaptability and focus on customer feedback.
