Not just fixing the bugs

But how much work the software does is not what makes it remarkable. What makes it remarkable is how well the software works. This software never crashes. It never needs to be re-booted. This software is bug-free. It is perfect, as perfect as human beings have achieved. Consider these stats : the last three versions of the program — each 420,000 lines long-had just one error each. The last 11 versions of this software had a total of 17 errors. Commercial programs of equivalent complexity would have 5,000 errors.

That was www.fastcompany.com on Software developed by NASA. The process emphasises not just fixing the bugs, but also finding the source of the bug and fixing the process so that the bug never gets repeated.
