I'm sure this is not unique, but this is a prototyping model that I've developed, and very much works for me. The key is that all ideas live in a Phase continuum all the time. Every single one of my (hundreds of) ideas moves around between these phases, and sometimes an idea gets stuck in a phase. That's ok. Disinterest and apathy about a particular idea is normal. If it passes, the idea might change phases and progress. Or it might stay stuck in a phase. Let it go, and move on to other concepts. When/if you return to it, the disinterest might have moved on, and so can the idea.
