Non-Production Minutes are referred to throughout L2L. This is particularly the case in relation to performance measurements as outlined in the Production Settings. Many Production Metric calculations take Non-Production Minutes into consideration.
When customers ask, "Aren't Non-Production Minutes and Non-Productive Minutes really the same thing?", Nancy Reagan rolls over in her grave and tells us in no uncertain terms to, "Just say NO!" (Some of you may have to Google 'Nancy Reagan Just Say No' to understand this reference.)
No, Non-Production Minutes are not the same as Non-Productive Minutes.
Non-Production Minutes are primarily planned periods of downtime: scheduled PMs, lunches, breaks, safety meetings, fire drills, etc. Possibly changeovers, training, and similar times when it is not possible to build product. You get the idea. These are also those times when you will not hear, "Why aren't you building anything?" That's a big clue right there.
Non-Productive minutes refers to those periods of time during which it is possible to produce, to build product; i.e. there are no active Down-Impacting Dispatches open and the line or cell is running. Another term for Non-Productive Minutes is Non-Execution time. During these instances, you can and should expect to hear, "Why aren't you building anything?" or even worse, "Why is nothing getting done?" *Legend has it that occasions involving Non-Productive Minutes are the reason the expression, "If you've got time to lean, you've got time to clean!" came into existence.
Planned Non-Production minutes are easily explainable. Non-Productive minutes, not so much.
