  • @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 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 7 months, 3 weeks 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]

  • @mike-carnell: My Fuschia belt was proudly acquired from ISSISSIPPI! Happy Easter to you down south.

  • @fabio71 – Fabio: Don’t worry about the methodology, learn them all. When you identify a problem that needs improvement, pull out the right methodology/toolset and get it fixed. Do you care how the plumber fixes the leaking sink, or just that the sink no longer leaks?

  • @Mike-Carnell – Wow, and I thought that I had time on my hands ;-)

    Not sure which is worse, those who are so oblivious of the thought process that they merely want to check boxes that various tools were done in various stages, or those who are BOK “purists” and will only use the specific tools advocated by their denomination of process…[Read more]

  • @AlexMoshe – What is the capability of the process?

  • As my buddy @cseider says, don’t worry about the shift. 1) It’s not 1.5 (however, it does exist but it is unlikely to be 1.5 – it will be unique for each measured item), and 2) If you are monitoring your process and adjusting (not over-adjusting, but properly adjusting) then you can reduce that overall shift dramatically.

    How did you select 1.33…[Read more]

  • Matt: At the GB level, you shouldn’t have any issues with statistics. As long as you understand some of the basics – mean, median, mode, what a standard deviation is and why it is important, and the basics about distributions. As @rbutler identifies, knowing regression and control charts will be a great aid. For GB’s, graphical analysis should…[Read more]

  • @Cor1 – some good advice you’ve received here. What I haven’t seen discussed is the need for a “burning bridge.” Do you have some aspect of the business that is struggling mightily? For a production or service company, is there a product or service or facility that the organization is contemplating terminating? Or, alternatively, one that is…[Read more]

  • @Helmet – Instead of asking for a “problem” you might approach the process owners with the query – “What takes too much time in you process to …?” or alternatively, “Where do you experience excessive rework (or redo)?,” or even “What is preventing you from doing more/closing faster?”

    As my friend @cseider states, it’s too late now, but a…[Read more]

  • MBBinWI replied to the topic Hypothesis Question in the forum Methodology 1 year, 3 months ago

    @cprao101 – just as a friendly suggestion, in such a situation, it would be better for you to posit an answer and your reasoning. That will likely get you a positive response.

    You were lucky that Katie got to you first. There are many more of us who wouldn’t have likely been so gentle ;-)

  • GB: Long term must be no better than equal to, and will normally be less than the short term. The real question comes as to what constitutes “short” and “long.” Regardless of how you define them, since “long” encompasses the possibility of things occurring that would not occur under “short” there will be more variation and thus a lower Cpk.

  • Jose: You’ve received some sage advice here. You are correct that a single value for Cpk isn’t always the best. However, it is often necessary to drive an objective with a simple standard. You should look at the costs of improving and the benefits of improving and make a reasoned argument as to the return on that investment. Good luck.

  • As my buddy @rbutler identifies, you need to look into the situation of the material effects. This looks like a split plot type design.

  • @itsmi – The reason that my friend @cseider suggests doing some analysis on the effects of the X’s (the independent parameters that you set or possibly affect the output) on the Y(‘s) is two fold. 1) To see if they really do have some effect. 2) To see at what level of change they have a significant effect. For example, you mention humidity.…[Read more]

  • @cseider – I’m shocked! ;-)
