I heard about a big software project that took a couple of dozen developers a few years to build.  The project had difficult security requirements that ended up having a login take over an hour to accomplish due to all of the verification between systems that had to occur.

The team went into a client review cycle knowing this was a big problem.  The client sat through the entire presentation and demonstration without a question.  Always a bad sign.

As the meeting was closing and everyone was gathering up their things one of the developers asked if the login time was a high priority or not.  (Duh!)

The client lead, while still gathering their things and not even looking up, said, “No.  We have a contract.  We will pay you for the software.  But, we are going to use something else anyway.”
