Difference between Agile, RUP and waterfall development models

Asked By Aerynn 10 points N/A Posted on - 11/07/2011

I would like to know the difference between Agile, RUP and waterfall development models. Do they support an interactive development and release process?

Will the other two accept the late inclusion of requirements unlike the one seen in Waterfall model?

Difference between Agile, RUP and waterfall development models

Hi Aerynn,

The waterfall type of software management was a development of the past and it was later improved to RUP which was more interactive compared to waterfall. RUP in full is Rational Unified Process.

Agile then was the latest but in comparison each one of them has it own advantage and disadvantage thus weaknesses and strengths. Each one of them for example suits a certain project environment better than the others.

Waterfall for example works well for complicated and critical applications for example NASA and the military which requires high levels of fault intolerance.

Difference between Agile, RUP and waterfall development models

Hello Aerynn,

The RUP (Rational Unified Process and Agile are more iterative and incremental models than the Waterfall model. Whatever, the choice among three depends on your project, business culture and environment.

Unlike the one seen in Waterfall model, the other two accept the late inclusion requirements.

But I think, Agile is better than other two. For more information go here:
