Which is all the more reason to give good credit. I have to justify effort I do on company time to my boss. If I had to put in months of work on company time, that needs to be clear to my boss's boss who may not know anything about programming but signs the check. Such people think writing code is the hard part, so it is easier to justify the costs if I'm given credit for writing code for several months (even though the code itself took a couple hours)
