  • 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. 10 years, 7 months ago

  • 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. 10 years, 7 months ago

  • 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. 10 years, 7 months ago

  • 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. 10 years, 7 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]

    – Control of documents
    – Control of records
    – Internal audits
    – Control of non-conforming products

    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 16 years, 11 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 16 years, 11 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]
