We make a big mistake when it comes to idea generation and innovation. We obsessively work out all the details, looking for proof that it will work, and when someone points out that it might just not work out, we do not like that and might just bail out.
Here is the thing, as most veterans in the innovation space know; ideas do not have to work as designed. In fact, the idea may not work at all and it does not have to! What we realise is that an idea is like a living organism, it evolves, like a virus, it does not really ever die! it keeps morphing into something else provided you do not give up on it.
The more you try to flesh it out, the more the idea mutates, the more exposure the idea gets to the outside world, the more it mutates until it assumes a form that hits with the target market (We call this stage product/market fit).
Even if only 10% of the idea works, it might be all you need.
