>I am not calling anyone here unprofessional. I argue in favor of applying best practices and that's what I attempt to demonstrate. Seriously I have seen a piece of software built over 3 years by 5 people which I demonstrated would kill patients. Would you agree that was unprofessional?

Of course. Programmers have no business killing patients and, like total amateurs, leaving written trace in the database.

That line of work should be the discretionary province of insurers, pharmaceuticals and the rest of the health/disease industry.
