Good point, but it raises the issue of checklists. If this area is too dangerous to tweak, how do you take care to avoid manual versions of these mistakes? Is there a step to search for words in the wrong case? Usually you'll find that the new idea is good, in some contexts, but that exploring it surfaces new requirements and existing ones that were poorly understood. Usually there are things that aren't being done correctly now, that when documented and planned for, change the equation. But the big benefit of outsiders isn't their ideas (though it often is), it's their ability to help cut through the insider problems. Usually insiders know what to do but are hampered by not only the difficulties, but the politics. Someone who doesn't know the conflicts can say that the emperor is naked, that doesn't magically clothe him but allows the tailor's who've been calling it out already to actually be heard and then the problem can actually be corrected.
