Is there is a 90% chance of a logic error per 150 lines per workbo

[Jay]

Can anyone confirm and provide references of occurrences independent of a
direct quote by David Permenter on page 149 in his book Pareto's 80/20 Rule
for Corporate Accountants (2007) published by Wiley ISBN 9780470125434 who
says -
" For every 150 lines there is a 90% chance of a logic error (from a recent
study)".

Can anyone give me the details of the study he refers to or quote where I
may get more information on this problem?

Thanks

Jay

Hi Bob,

I shall go through the different references on both URLs suggested and they
appear to be at least focussing on the error or problem reported by David
Parmenter.

Thanks

You're welcome, basically anytime you have piles of code there will be
bugs. For instance another rule of thumb is, "For every two programming
bugs you correct, you will create another." That "study" just reduces
the reality of coding to statistics.
