There is a very nice paper that showed up on recently.  This is well worth reading, either for yourself or as the basis for introducing these topics to your colleagues.

Best Practices for Scientific Computing

Aruliah, et al. Oct. 2012

Scientists spend an increasing amount of time building and using software. However, most scientists are never taught how to do this efficiently.
