What are the differences between iteration and waterfall methodologies?

What are the differences between iteration and waterfall methodologies?

The waterfall methodology is a linear approach where each phase must be completed before the next begins. In contrast, iteration allows for repeated cycles of development, enabling adjustments based on feedback.

Can you give me examples of when to use each methodology?

Sure! Use waterfall for projects with clear requirements and low chances of change, like construction. Iteration is better for software development where requirements may evolve.

What are the advantages of using an iterative approach?

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

Are there any disadvantages to the waterfall method?

Yes, the main disadvantage is its inflexibility. If requirements change after a phase is completed, it can be costly and time-consuming to go back.

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.
