    C,
    If my memory serves me right the ‘D’ in 8D stands for Discipline – as in the 8 Disciplines you need to follow in order to kill the problem.  These Ds have been in use since the early days of TOPS (Team Oriented Problem Solving).

    That’s the one.  Thanks David.
    Amy, there are other postings around this – Eileen Beachell’s name is worth a further search.
    Good luck in your hunting.

  • Yes. 
    If you were to do a cap study on a machine using a CMM and your micrometer – the numbers would be slightly different (resolution) but the overall value will be very similar.
    With apologies to all who posted earlier for jumping in and answering this.

    Amy,
    One of the people involved with the creation of the 8D has posted to this forum before now – I’m ashamed to say I can’t remember her name – but if you use the search facility on previous postings I think you’ll trawl more than enough information.
    Good luck

  • If you apply either a prioritisation technique (e.g. ranking), or just go for what the team feels to be the most vital effects in order to reduce the number of metrics you have, then you run the risk of intentionally ignoring a factor which may be the solution.

  • James A replied to the topic Calibration Eqpt in the forum General 19 years, 2 months ago

    Broadly I agree with Girish, but if you have an area dedicated to calibration (and storage of ‘spare’ measurement equipment) then you can safely keep the “Not in Use” equipment in that area, and thus safely out of the way of people who may wish to use the equipment in its uncalibrated, albeit “Not in Use” state.
    If it’s out of the engineering…[Read more]

    Sarah,
    Trips to Hawaii?  Recognition dinners? Bonuses?  Wow! Who are you working for??  We don’t get incentives, we just get to keep our jobs!
    But seriously, I do agree with your general sentiment that aiming only for the big savings seems wrong – I don’t believe that you can peg a SS hat on a project on the basis of value alone – although it is…[Read more]

  • Amen to that.
    Thank you Mike for an excellent response.

  • Raymond – I’ve never yet used one of these, but have been able to track down the following references which may be of help (or they may not)  “Implementing Six Sigma” by Forrest W. Breyfogle III has a large-ish section on CUSUM charts.  MiniTab’s Help section also goes into some detail (with worked examples) if you have access to a copy of t…[Read more]

  • James A replied to the topic KanBan in the forum General 19 years, 2 months ago

    In a previous professional existence, when I set up and ran a Kanban system, we only used tokens at the machining operations – these were arranged in columns (according to part and op number) on boards.  As each box of parts was completed, the token was removed from the board and placed in the box with the components.
    As each machine was r[Read more]

  • Jill,
    I’m not in the medical world – but I would suggest that you start by getting from all your key ‘Heads of Department’ exactly what it is that they would use as measures of success – i.e. determine their ‘Critical to Quality’ items in order of importance.
    What does ‘Admissions’ have as CTQs?  Does this compare with what those being admitted…[Read more]

  • My pleasure.  Thanks for the explanation, it makes sense, now.

  • Marnie,
    If you already have an historical value for s then I would be tempted to use X bar moving R charts (or soft equivalent with a sample size of 1) that way you can use all the points from the previous month, and use the existing s-value (+/- 3sd for limits), if there has been no change to the process.  The only question I have is – What wil…[Read more]

  • James A replied to the topic Six Sigma in the UK in the forum General 19 years, 3 months ago

    Cat,
    There are a number of us in the UK who also post here – but we are usually only detectable by spelling and phraseology.  For various reasons I prefer to remain relatively anonymous beyond revealing my country of origin, but if you post your mail ID, I’ll contact you.

  • James A replied to the topic Help..!! in the forum General 19 years, 3 months ago

    That depends on the culture within your company – where I am it can can be recognised that improvements are there to be had, but they may have constraints imposed upon them – therefore we could close the project as the BB input was complete.
    It may be different for you where you are – and I cannot tell you what to do as your company may well be…[Read more]

  • James A replied to the topic Help..!! in the forum General 19 years, 3 months ago

    If you have identified what needs to be done to gain the improvements, and all parties agree that this is the case – yet the constraints of the business prevent hiring of the necessary staff, then I would suggest that that is a business issue – not a 6S one, and is therefore outside the scope of your project. So close the project.
    If it is a case…[Read more]

  • Kerem,
    At least one of them works in the textile industry – at least that’s what I read from the content of the discussion.

  • Kerem,
    Try this thread for clues – you may be able to get some of the contributors to contact you?
