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]
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.
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.
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.

All you need is documentation for ISO9001:2008.** 2 basic DOCs:
– Quality Manual
– Quality Policy** 6 compulsory DOCs:
– Control of documents
– Control of records
– Internal audits
– Control of non-conforming products
– CA _ corrective action
– PA _ preventive actionTo write your Quality Manual, use these chapters:
– Sec.5:…[Read more]
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]
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]
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]
Ford Motor Company has got very good materials on Consumer Driven Six Sigma and Lean Manufacturing! Visteon being Ford’s sister concern all these years, the material is available amply! May be you need to check up with Visteon North America or European operations! I think you can still get it from Ford, being the major supplier an…[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]
