But good programmers using good practices write orders of magnitude less bugs than bad programmers following no practices. We may not be able to eliminate 100% of software defects, but we _can_ improve what we are doing by quite a bit. Remember you (and likely most of the people here) are atypical of programmers in general. You can't realize just how _poor_ the average programmer is until you've spent years trying to find _good_ programmers to hire. They are very rare in my experience. > And the best software engineers have no idea how to prevent them. I disagree. They don't know how to entirely prevent them, but they certainly know how to minimize them. Lockheed-Martin took their software defects down by a factor of ten by implementing good development processes over a 5 year period up to 1991. Since 1992, they've knocked another factor of 5 off their defects. And they have increased their LOC/hour rate by a factor of five: More code, less errors. <URL:http://www.stevemcconnell.com/articles/art02.htm> <URL:http://www.dtic.mil/ndia/2004cmmi/CMMIT5WedAM/CMMITechConfBenefits2004Version4.pdf> They are obviously doing _something_ right.

Or it may rise to the level of the other licensed professions where you can be confident of a minimum level of competency. You don't usually wonder whether a doctor is qualified to be a doctor. The licensing system is good enough that that is not usually a problem. We need to reach that same level of confidence about the programming profession. > Michael Kay > > P.S.
