Parts Count Variation

Parts Count Variation

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.

To see a draft of the paper, visit the References section of the site, click Draft Comparison of Electronic Reliability Prediction Methodologies, or via the pdf view window below.

Enjoy. And, if you know of other studies of this nature. Please let me know and we’ll at least post a link to the work.
