    This is a common mistake with software development.  Assuming someone can somehow write specs and know the requirements ahead of time, so all you have to do is deliver those at the end.  The evidence is the 4 hour a day maintenance down time.  An assumption that there would be a need to modify and update the software regularly would have driven an architecture that would allow for zero down time deployments with easy rollback of deployments if there is a problem.  It is something that may companies do, so it is not like they would be doing something bleeding edge, and if built into the architecture from the start, it can be much easier.
