The Bob Bug Syndrome

Some bosses make the mistake of thinking that if the result of someone’s work is easy to use, the work itself must be easy.

A guy goes in to consult for a company and runs across a bug. He raises the issue and the boss says “Oh boy – another ‘Bob bug’ – Bob created a lot of bugs.” (Bob has moved on by now). After the guy was there for a while he comes to realise that Bob wrote most of the code while the rest of the staff wrote very little. The perception that Bob created a lot of bugs was technically correct, but an analysis of bugs per line of code written show that Bob actually made fewer mistakes than his co-workers, but since he generated the majority of the app, he had the majority of the bugs.
