Just a short post to point to a paper on the accuracy of part count prediction techniques. A few years ago, I recalled seeing a paper that studied the difference between various parts count methods and actual results.
Jeff and colleagues did this work some time ago, and in most cases, the underlying parts count methods have remained relatively unchanged, so I suspect the results are still very relevant.
The bottom line – expect as much as -100% to +500% different between the prediction and the actual result.

Great paper. Thanks Fred.
One of the benefits of attending a conference – ran into one of the authors – cheers, Fred
