I think that I would have to take exception to your comment about it not being the suits fault...
If the requirements statement was correctly written and then the contractor was kept to a correctly written contract, then you wouldn't have these issues.
We had some serious problems with our itteration of the "new" and "improved" NAS. or ISSS as it was known. We finally were able to convince the suits that this was NOT going to work in a manner that was better or even as good as the old system. It was scrapped and then we took what elements did work and to save money put it together into something that would at least work and replace an old and failing system. Now we are working at slowly replacing all the other items that need to be updated. We know that the NAS software is VERY COMPLEX and must work all the time in real time. We are not in a hurry for the sake of safety and the customers....
