I just came from a Lead Assessor Training here in the Philippines. My trainer there tells us that don't say the clause on Statistical technique is not applicable. Any evidence that shows the company is doing what it can to analyse data should be part of this element. But our Australian consultant tells us Statistics yes, but Statistical Analysis is an altogether different thing, ergo, NA. I've had at least 2 assessors saying no, and 1 says yes. Your site offers advice to not include SPC if its not applicable. We're in the convenience store industry.
