  • @kaizen4all – In addition to my friend @Mike-Carnell suggested readings, I would encourage you to read “The Goal,” by Eli Goldratt. In it you will come to understand that every system has a constraint, and only by improving the constraint can you make real improvement. I’ve seen too many folks attack an issue because it has low capability,…[Read more]

  • @alfavictor1 – The purpose of a DOE is to establish the relationship among the variables. If you have a simulator, you already have that relationship, so no need for the DOE.

    You might want to look at taking your simulation and adding a Monte Carlo aspect to it. This will allow you to add the variation for the variables which can give you…[Read more]

  • @cseider – still might have, who knows?

  • @RoryOBrien – ah, but did you use a methodology? If so, then map out what you did. Otherewise, stop trying to fool your superiors.

  • Sandesh: You seem to be confused on the terms you are using. I believe you mean Cp, Cpk, and GR&R.

    As for your question on doing the analysis in 3 dimensions, that will depend. Is the item fixed and the instrument needs to be moved to the location to be measured? If so, that may influence the reading obtained. Are the dimensions…[Read more]

  • Sandesh: That will depend on who is requiring the capability data. For example, I had a recent stint as a QM for a Tier 1 auto supplier. The customer specific requirements demanded all special characteristics to have their own capability studies. Generally, for a specific characteristic – say drilling a hole – of the same tool in the same…[Read more]

  • @RoryOBrien – You seem to be trying to force a solution into a solution methodology. I wouldn’t worry so much on what you call the solution methodology.

    Since you have already “solved” the issue, it seems that you are more interested in demonstrating the solution is effective. In that vein, I would suggest that you create an apparatus that you…[Read more]

  • @shanecharlton – You first posted about 13 hours ago, and after only 4 hours of waiting, you are already jumping to decisions on how to proceed. I suggest you find a mentor – either from a local consultant or a community college or other individual who can review what you are looking at to provide some guidance.

    From what you posted, I would…[Read more]

  • Excellent advice @rbutler ! I can’t tell you how often I’ve been mentoring a project and had the project leader be hoodwinked by such influential data points. When challenged, typically they will find out that those points had some irregularity about them. I always recommend to my belts that they start with a visual examination before they look…[Read more]

  • Excellent advice my friend @Mike-Carnell. How are things in the DR?

  • You will find a problem in any circumstance where there is less than the ideal situation. Thus, you can well imagine, there are problems everywhere! The real key is not in finding problems, but in selecting the right problems to fix.

    I would suggest you do some reading on Theory of Constraints (TOC) – start with the book “The Goal” by Eli…[Read more]

  • Excellent advice from my friend @cseider.

    You might want to number the batteries and the forklifts and gather some data on how long a charge is given to each battery and how long it takes in each forklift to run down. This will take some time to gather sufficient data to make any meaningful analysis.

    You will be looking for certain batteries…[Read more]

  • You are trying to apply a normal distribution analysis to a non-normal situation. When time is an element, you are bounded on the lower end by zero time. Oftentimes, the actual measured time is sufficiently long so that a normal distribution is acceptable. When the outcomes are bounded at the lower end by zero time, a Poisson distribution is…[Read more]

  • I vehemently disagree. If a defect “isn’t important” then it isn’t really a defect. This approach is a feel good attempt to justify not addressing defects. Anything that doesn’t conform to the requirement is a […]

  • @umav104 – You’ve received good advice here, especially from my friend @mike-carnell, but I’d like to go back to your original question. An audit is merely to check that other checks are being done, and as Mike states – they should also verify that those checks are adequate for the item being checked. Thus they should not only check that the…[Read more]

  • MBBinWI replied to the topic DMAIC for FMEAs in the forum Methodology 1 year, 3 months ago

    Carolina: I’m not sure what you mean by a “DMAIC approach” to FMEA. In it’s purest form FMEA is meant to identify what might go wrong before it has been created so as to design out those failures. DMAIC is a problem fixing methodology, thus, you have already suffered the failures. As someone mentioned, you might use FMEA during the improvement…[Read more]

  • I will second my friend @cseider in recommending moresteam.

  • @rieam – it is typical to target a 2 std dev improvement. As you have seen, one std dev was easily achievable.

  • @Hutch44 – Business is “OK” means that nobody is getting fired for the performance, nor that anybody is going to get a bigger bonus for making it better. This is a reality of business – what’s in it for me? Find the answer to that question and you will have found not only the sponsor, but the value of making the improvement. Good luck.

  • MBBinWI replied to the topic Good Morning iSixSigma in the forum Welcome 1 year, 8 months ago

    Welcome to the forum @Hutch44!

    A word of advice – if you have a question about how to do something, we expect that you have already tried to reason it out yourself. Post what you are trying to do, and what you have tried and what you seem to be having a problem with. If you come here with “homework problems” and expect us to give you the…[Read more]
