“You can go to the board of directors and get approval for building a billion dollar atomic power plant, but if you want to build a bike shed you will be tangled up in endless discussions.
This is because an atomic plant is so vast, so expensive and so complicated that people cannot grasp it, and rather than try, they fall back on the assumption that somebody else checked all the details before it got this far.
A bike shed on the other hand. Anyone can build one of those over a weekend. So no matter how well prepared, no matter how reasonable you are with your proposal, somebody will seize the chance to show that he is doing his job. That he is *here*.
This is metaphor indicating that you need not argue about every little feature just because you know enough to do so. The amount of noise generated by a change is inversely proportional to the complexity of the change.”
