Formal Development in Programming

The rate of programming errors can be reduced dramatically by new formal development techniques, such as cleanroom development.

The goal is to prevent errors from occurring in the first place.

This requires a mathematical proof of correctness for each piece of code. Few programmers are trained in this technique. In addition, its results to date, while very encouraging, seem to be about as good as one can do with normal development followed by code inspection.
