I am about five months into burning time and money brainstorming for a solution to a problem. Our client insisted in having "the team" participate. Never mind that we knew exactly where to go and what to implement five months ago (experience matters). We could have been a couple of iterations into a real solution by now (this is hardware+software) rather than being nowhere while everyone understands what they don't understand and finally understands that what we said five months ago was the correct path. Rather than being critical, sometimes one needs to realize that people and organizations, at times, require going through a process before accepting reality or agreeing with a conclusion. I've seen this many times during my career, from simple problems to designs that are currently orbiting our planet. It's unfortunate because it burns time, money and valuable human capital (people could be doing far more valuable things).
