@IM_CTF A2. A combination of market and customer needs/survey's. Sure some things are invented w/o a defined market (post-it, paper clip etc). It makes it easier if you can define your ROI early in the project. #im74
@IM_CTF A1: Depends on whom generated the idea. Was a bunch of SME (subject matter experts) or a new employee fresh out of school. SME, I would trust the intuitive way more than the rational way. In the end I think it might be a combination, and that it can change over time. #im74
@IM_CTF A2. Old habits and routines. "if it works now, why should we change it"... Usually time and money are the two big obstacles that you have to overcome, once you have an idea that everyone thinks is good and worth implementing. #im74
@IM_CTF A4) By a detailed desciption of the idea, how it will ad value (or money), a short desciption of how you see the next step and finally if you can estimate an inital cost. #im74
