I am no engineer but my understanding of Sigmas tech is that it provides quality assurance in production runs of parts based on the analysis of the creation of many parts on many machines in any location under any condition at any time that all parts would end up synonymous with each other as to there end quality. Meaning the beta testing would need to be done under all the fore mentioned conditions before all inclusive monitoring could begin for a production run. If anyone here who is an engineer could refine my understanding if necessary or qualify it I would much appreciate it.
