Every working team needs that sort of person. Someone who’s always suggesting the kind of ideas that might not work; ideas that can change the status quo (both externally and internally) and challenge the normal order of things.
New, disruptive, unconventional and a lot of times, ‘impracticable’.
More of these kinds of ideas, of course, means two things:
First is that, a good proportion of them won’t fly, because it will probably go against the system. It will go against, “the way we do things here”.
Second is that, the more ideas that are generated (bad or good), the better the odds for something new that might work and the chance for innovation. The more bad ideas we come up with, the better our chance of having a few good ones. At least a bit more and enough to stay ahead of the competition.
