James points to a discussion of the hard transition Data Entry folk do when moving from a “Green Screen” application onto a GUI based app (web/win).
I totally agree. The issue actually dawned on me a couple of weeks ago. I was talking to a friend who works at aviation. In one of our chats he complained that “Now they're making us move to a whole GUI based system. I don't see what was wrong with the old one! I could enter data at the speed of though. Now I'll have to use the mouse!”
He's totally right. It would be much slower for someone who memorizes beeps and keystrokes to move to a web based interface. The experience can be encapsulated into a new GUI windows app, but it would still be hard for the app devs to create an app that mimics the old one as accurately as desired for people not to have growing pains.
