The Phase Concept
The “top-down” and “investigate alternatives” principles result in the following workflow when resolving a problem: Idea, development, implementation planning and delivering a solution. Each of these must be broken down into individual work packages, or phases. Each phase must be distinct from the others in terms of time and logic. The purpose of this is to break down the development of the solution into chunks, thus giving a clear overview. This makes it possible to draw up a graduated planning, decision-making and implementation process, with predefined breakpoints (milestones) or intervention points.
