I used to work for a consultancy that almost exclusively worked for the German armed forces. And pretty signficant chunk of these contracts evolved around requirements and specification documents. Basically we wrote them, the way the armyed forces wnated them to be written, and they just signed of on them. That was equally shocking as it was hilarious sometimes. The sad thing, almost the complete management of that firm, and the majority of employees, used to be former Army, Navy or Airforce. Or from the civil admin staff. I always wondered how much value we actually created, the amount of additional expertise was quite limited.
