Not, is very realistic if you deal with non-developers. You could deliver something in 1 hour, BUT, the customer/person that could answer you WHAT to do exactly will take days/weeks to be AVAILABLE. This is not a joke. For one of my very recent jobs, I need to wait 1 FULL YEAR TO MOVE ON. Then weeks after that. Despite already being paid in half! -- Developer time is NOT ONLY the time the developer smash the keyboard.
