I am looking for metrics to help determine improvements in our FEA process.  I was using "time spent per project" as a metric, but as scope and detail has increased, this metric is not that meaningful.  I do 25-35 projects a year, so PPMs are probably not the most appropriate either.  Does anyone on this forum have a recommended way to track their efficiency and/or performance gains in FEA?  Thanks

RE: evaluating FEA effectiveness

"surely" the true gain in using FEA is the time saved compared to hand calcs/alternative methods.

i'm willing to bet that at least 90% of your models have unique features that require learning (and re-learning) with each project.

the most meaningful metric is "did the model make the correct predictions ?"  give yourself 0% for an inservice failure that should have been predicted, and 100% in the absence of inservice failures (the benefit of the doubt ?).
