When I worked for a local government we, as in the users, designed a database app based on what we actually did. Since none of us knew how to use any of mictosoft's code products, we used a spreadsheet with macros as our demonstrator. We tested it with actual data that we compared to what we were were using. Pretty as a picture, very adaptable and had a lovely GUI. Our in house IT staff thought highly of it as well.
Unfortunately, all we got was an adulterated version of another database we used in a different department that was universally hated by them.
Here's the kicker. A couple of us would regularly find key combinations and shortcut the provider didn't even know existed. And several were quickly erased. I guess it doesn't pay to show up the "experts" or point out the errors and fallacies their in-house "pros" created.
