Re: Government/defense spending
Been there but there is the other side of the coin that is oft overlooked.
Literal last second updates to the specs or requirements that blow the whole project out of the water thus rendering all work done up to that point a total waste of time and resources.
Example - ministry asks for quotes on a facility monitor system with the usual data security requirements and a tight budget. Two onsites to literal middle of nowhere .... they had only one Timmies ... and there was only two of us left willing to bid on the project by that point.
Then the Facility manager drops the bombshell that any cables must be in conduit even though we can see all the loose cables zip tied to the cieling structure. Do as we say and not as we do. The conduit installation would have taken the whole budget. AFAIK the project is still under review after a decade since inception.
