I have been reading the article entitled "A manager's introduction to RUP" and I have some doubts about what does iterations really mean on this methodology.
For what I know RUP has 4 phases: Inception, Elaboration, Construction and Transition; each of these phases has some "deliverables" or milestones that should be accomplished before going to the next phase.
Apart of that, I have like 9 disciplines that range from Business Modelling, Requirement elicitation, design, among others and ending with the environment phase. So if I want, for example, to make a selling system for a drugstore I suppose that my project should pass thru these 9 disciplines in each of the phases mentioned before.
So the iterative nature of RUP means that I can jump from top to bottom and bottom to top in these 9 disciplines for refining purposes; and should I do this for each of the phases? Or the iteration part means other thing?
