Poul-Henning Kampin applies C.Northcote Parkinson’s Law of Triviality in to explain the disproportionate attention given to trivial details in software development . It applies rather well to design:
Should I care what color the bikeshed is? The really, really short answer is that you should not. The somewhat longer answer is that just because you are capable of building a bikeshed does not mean you should stop others from building one just because you do not like the color they plan to paint it. This is a metaphor indicating that you need not argue about every little feature just because you know enough to do so. Some people have commented that the amount of noise generated by a change is inversely proportional to the complexity of the change.
To expand, wikipedia has:
Parkinson dramatizes his Law of Triviality with a committee’s deliberations on a nuclear power plant, contrasting it to deliberation on a bicycle shed. A nuclear reactor is used because it is so vastly expensive and complicated that an average person cannot understand it, so they assume that those working on it understand it. Even those with strong opinions often withhold them for fear of being shown to be insufficiently informed. On the other hand, everyone understands a bicycle shed (or thinks he or she does), so building one can result in endless discussions because everyone involved wants to add his or her touch and show that they have contributed. While discussing the bikeshed, debate emerges over whether the best choice of roofing is aluminium, asbestos, or galvanized iron, rather than whether the shed is a good idea or not.
