A really really really shit piece of software, that companies have the misfortune of using. Its slow, unreliable, unpredictable, and just generally crap. The developers never really do anything to embrace the needs of thier customers. It tends to hide windows randomly and delete or change orders, just because it can. It needs to be restarted on a server once a day, just so it can last out a working afternoon. Integrity software are just basically laughing at the fools they've suckered into buying it.

Vision user 1: "Well i know that. but has anyone pressed more than one button in a minute and caused it to freeze?"
Vision user 3: "Yeah i sent a document to print. I think its stuck the whole system."
Vision user 2: "No surprise there. Im going to go downstairs and piss in the server."
