Dismissing an idea is so easy because it doesn’t involve any work. You can scoff at it. You can ignore it. You can puff some smoke at it. That’s easy. The hard thing to do is protect it, think about it, let it marinate, explore it, riff on it, and try it. The right idea could start out life as the wrong idea.
So next time you hear something, or someone, talk about an idea, pitch an idea, or suggest an idea, give it five minutes. Think about it a little bit before pushing back, before saying it’s too hard or it’s too much work. Those things may be true, but there may be another truth in there too: It may be worth it.
Every solution is great in some circumstances and terrible in others. Design debates are best settled by inviting everyone to present their solution, but also explain under what circumstances their solution is terrible. Finally they’re asked to explain under what circumstances their colleague’s solution would be better. This is what Bill Buxton refers to as walking on both sides of the street.
The person who demonstrates most knowledge about the shortcomings of their own solution and the benefits of all the alternatives is the best best equipped to make the call.
