Rao replied to the topic Process, Cycle, Lead Time in the forum General 12 years, 4 months ago
Process = 3
Batch + queu = 120′
Cycle time = 15′
Lead time = 135′
WIP = 25Care about lead time, it normally includes supply chain duration + manufacturing time + shipping time until the customer receives the goods.Helpfully yours.And now, continue to locally improve:
. use statistics and DoE to frame the cycle time
. accelerate the overall…[Read more] -

Mike,Two for you : “adaptive-loop” + “supervision-loop”.One for me : NO “actuation-loop”.Man, you toughen up and you win!L/Gents, ‘ll be back.

To avoid ambiguity (or nonsense -;), Use the term “actuation-loop”” instead of “control-loop”. I repeat that anyway there is no regulator and “actuation-loop” is open.Solemnly, I declare that the absence of regulator/”actuation loop” is a downside of SS methodology.

Mike, Of course, there are M-A-I “adaptive loop” and C “supervision loop”; I agree they are closed. But nowhere exists a “control loop”, that loop is OPEN.

Ok Mike,But don’t forget the post#1 missive: on 25th April 2002, Jonathan Breen wonders if there is any downside to implemnt 6S strategy.

Mike, This is not philosophy. It’s Automatic Control taught in any serious bachelor course, precisely since the 50-ies.

Ready to refresh your concepts of cybernetics?
There is a triple kind of loop: the control-loop, the adaption-loop and the supervision-loop.** Control loop, or closed-loop** One uses the measure to control/improve the system directly through a regulator. “M-A-I” of DMAIC nor DoE does not work like that.**Adaptation loop** This is DMAIC. One…[Read more] -

Wake up Jonathan. Maybe you’re a genius, in any case a fabulous host. An 8-year-old post that generates as many passionate reactions! Seems all relevant answers haven’t been given?Any how, DMAIC is an open-loop cybernetics and DoE is an empirical walk aren’t they. So don’t dream an univocal answer to your post.

Great!Anonymous Markiemark, your “Look up in right hand corner” is useful for me. Thanks! I personnaly have to propose around 20 projects per term. It’s not so easy to imagine/offer new ones. But this list will boost my capacity to renew my already pretty owned one.

Rao replied to the topic How 6 sigma reduces cost? in the forum General 12 years, 4 months ago
Goldy,Think it optimal.
There are 2 sorts of quality cost. Have their slopes in x-cordinate=QUALITY and y-cordinate=COST:
1) Cost of service/output defect: low cost if high quality (less scrap), a curve of negative slope,
2) Cost of quality management: high cost if high quality (more control, reporting…), a curve of positive slope.
Their…[Read more] -

Rao replied to the topic Global 8D vs. DMAIC in the forum Software/IT 17 years, 6 months ago
Dave, Richard & Bruce have given a good picture on this. My experience at Ford was the use of 8D for fire fighting purposes to stop re-occurances. It can be used as an advanced incident reporting & analysis tool. However Six sigma is more of a methodology not only to identify the fire fighting exercises but also the potential failures. At the mo…[Read more]

Hi Stan…..
There is no ‘nonsense’ running here! If you look at what I have mentioned, Lean can supplement Six sigma. But there are companies that use only ‘Lean’ and they don’t have Six sigma to run their businesses. Before Six sigma era, major mfg companies were flocked to Lean manufacturing fundamentals. Hope this clarifies your so-called…[Read more] -
Rao replied to the topic Lean Sigma WORKS in the forum General 18 years, 8 months ago
I wonder if anyone differs with your statement. We have seen that Lean Initiatives will go hand in hand with Six sigma and they are considered as a major tool in the “Implement” phase.

Rao replied to the topic Six Sigma vs Lean in the forum General 18 years, 8 months ago
Here goes my two cents…….
Lean initiatives are basically driven by pre-designed processes. Six-sigma is the methodology which is driven by the custom processes designed on the ANALYSIS. Hence it is flexible when compared to using the tailor made solution. This is the major difference between the two. Lean initiatives can be used to supplement…[Read more] -

Recently I had an opportunity to meet with some of the senior officials in Motorola and this was the same doubt I put forward to them! There was a time when Moto used to manufacture the pagers and they were so strong in their quality that no checks or inspections were carried on line or at service centre! If any pager gives a problem, they used t…[Read more]
