George entitled "Lean Six Sigma." There is a table in chapter 3, page 37 that shows what would be considered "world-class" in terms of cycle efficiency for different industries. Machining - 20%, fabrication - 25%, etc. Good luck. You might refer to a book by Michael L.

If the numerator (cycle time) was reduced more than the denominator (PLT) PCE will get worse! Dear me.-- Maybe a distinction should be made between "cycle time" and "value-added time." If a significant portion of the cycle is not adding value then that should be subtracted in order to calculate an accurate PCE. It might be lower but at least you would know the true value. Of course it would make less of a difference if you have very short cycle times compared to your production lead time. –Another interesting thing occurs when a team actually takes some waste out of the “value add” cycle times in addition to removing some of the “non value add” inventory or queue times.

I followed your video on how to calculate Process Cycle Efficency.....I was alright until I got to the part: "Divide 97 by 64,530.....and thats how we get 0.15%"....... My calculations show the figure to be 0.0015%...........obviously I've done something wrong.......or have I? Liked everything else but this is really defying my logic...would appreciate your help. Chris Hi,

If his philosophy and techniques are spread across the industrial world, savings will be in trillions of dollars. He should open his office in India, Brazil, China. I wish Mr. Ron a grand success. It is unfortunate that I came acroos his sight very recently. Mr.Ron Pereira is doing a wonderful job.
