    Such a tree is ludicrous.
    I’ve witnessed teams achieving 6-sigma levels by doing any combination of the actions mentioned. And the same is true for teams that never achieved 3-sigma.
    Actually, the whole sigma level discussion is filled with assumptions and inconsistencies that detract from the commom sense approach of measuring improvement…[Read more]

    My 2c here…
    Six Sigma is definitely a problem solving methodology in most firms. A few of them have evolved 6S into the way they do business. Now, some call that a management philosophy. Rog will disagree. I would ask then what the definition of “management philosophy” is and another useless thread would be initiated to discuss trivialities ad…[Read more]

  • WRV,
    Malcom’s advice is sound.
    One additional comment: try to identify one or two of the most critical processes for the business. Where are the largest pains? What can add the greatest perceived value to the business or customers?
    I say that with the background of working on a very fast growth high-tech firm where even insituting basic…[Read more]

  • By the value it adds to the organization. Now, that’s pretty ambiguous…
    I’m am thinking of organizations that aim to reach profits.
    One good proxy for “value” is financial benefit to the business. This can be soft or hard. Sometimes dificult to estimate but definitely possible to estimate.
    You’ll hear a lot of non-financial value added…[Read more]

  • Points well taken John. However, plotting “true” non-normal data with an Individuals chart is likely to show that the process is out of control, which is not always the case. 
    Lastly, note that the Box Cox transformation generates new data but also new UCL and LCLs for the data. Out of control conditions may exist even after the tr…[Read more]

  • Just today I was looking at a chart of chemical levels in one of our processes. It is an I-MR chartand it looked out of control. Looked at the data distribution and the data was not normal.
    Did a Box-Cox transformation and plotted a new chart (with the transformed values) which now is no longer out of control.
    In summary, a control chart…[Read more]

  • It depends on the type of control chart being used.
    An I-MR chart requires a normal distribution. A X-bar-R charts does not require a normal distribution based on the central limit theorem.

  • Josh,
    I think some answers have missed your point. You made it clear that you valued other skills but had some minumum requirement for TECHNICAL skills. To that point, I think that you technical skills expectations are very reasonable?
    No doubt we can solve a lot of problems with soft tools (process mapping, C&E matrices, etc). However, a Black…[Read more]

    Be specific as to what your role was in the project. Too many people talk about projects they worked on but when you get to the bottom of it, their role was small.
    I don’t think this is only the candidate’s fault, the employer should target specific answers during the interview.
    My 2c.

  • To add, this would not happen if you were using an Individuals chart (I-MR, for example)

  • Anyone can use DMAIC and 6S tools and techniques. While certification is not a requirement, it is important as a driver for accountability, results and institutionalization of change.

  • The order does not matter. There will only be a sign change in the coefficient of your main effect.

  • According to the data available in this site, somewhat of a normal distribution, roughly $100K +/- $40K.
    I discarded MBB salaries below $50K as bogus data.

  • Very good point Stan. I had the same feeling when I first read it. He should have given credit to Taguchi on his model for “excess costs”.

  • McD,
    My frustraion with sigma values is at the core of this thread. Assuming that you buy that the long-term 1.5-sigma shift applies to all proceesess, how do you measure a sigma value for the whole business? what if specifications change with improved performance?, etc.
    Sigma values tend to lead organizations to “play with the numbers”. I bel…[Read more]

  • Aggregate monetary benefits of realized process improvements is the best metric to represent the effectiveness of Six Sigma implementation in an organization.
    All other metrics (customer satisfaction, reduced defects, increase in employee morale, training effectiveness, etc) can be translated into this one.
    I see too much effort put forth by…[Read more]
