Very well described on SPC, and I like how you describe SPC tools as more effective from cost a perspective.

With newer technology, we can accumulate all standard SPC procedures and make them automated so that, in the long term, the quality control process would be automated and maintained with complete accuracy in production. Indeed, the cost is less for SPC. However, with the competitive world towards automation shift, every company needs to start investing in new technical data analytics solutions to impact growth significantly. What will be your thoughts on Machine Learning instead of SPC?
