Iterative Planning Processes; Supporting and impeding factors

Basically, using the phrase “iterative” means there is a stepwise movement towards a (the) goal, instead of a “momentary leap” from problem to solution, where, at intervals, the situation is evaluated and necessary steps are taken to ensure the process is “on track” towards the solution. Such steps will normally be like loops, where you go backwards in the step-line and kind of “run it through a new cycle” (see example of Basic Iterative Process/John Wright Company).
