Along with the posts above, assuming there is funding available and a separate group to drive the innovation, there is always the problem the innovation being brought up in a wrong time. It could be a novel and achievable idea but maybe the market isn’t just ready for it. If the idea is too early upon its time, then team can probably study trends with regards to the innovation. If there is no market available at that time then it would be better to postpone it and prioritize other project. For instance, similar situation happened with Google Glass. The innovation was remarkable but the market just wasn’t ready to accept it. The production was halted and postponed till the time when people would be ready to accept such technology.
