  • I (or more accurately my teams) have used it many times for DMAIC and more so for DFSS projects. In my case we use a specific QFD tool such that the concept selection work flows naturally from either your QFD-I or QFD-II matrix.

    Generally I find working on cross-org/cross-functional that it’s not difficult at all to find multiple competing…[Read more]

  • Depends on your environment (e.g., I worked in one where management changed direction / goals every other month – literally), maturity/capability of process, as well as work load for BB. My BBs rarely worked less than a couple of projects at a time so when I say 9 months that is not dedicated time but elapsed time. The luxury of focusing on just…[Read more]

  • Yes, answers depend completely on the nature of the projects (e.g., capital or expense), maturity/capability of the process that is the subject of the project, etc.

    That said I’ll give you some very GENERAL responses with qualifiers that I’m sure others will add to in follow up replies:

    1. Typical investment, at least initially, is mostly…[Read more]

  • Don’t get me wrong – a good provider for training is essential but to me it’s just table stakes. Beyond the basic training I think the mentoring work of how to apply the tools/concepts you learned in class is MORE important than the class alone. There’s many people who have gone out and obtained a certificate from completing a class and passing…[Read more]

  • Short answer is no but don’t fret. You need someone with actual experience to guide you through proper use of the tools but there are external options. If you check here or at asq.org you will find a list of 3rd party Lean Six Sigma trainers and many of them will provide access to a mentor (phone, web conference, etc.) and their own…[Read more]

  • Hi Arturo.

    I’ve always thought of PDCA as more of a framework and formerly a methodology. In this context it was a precursor to DMAIC and other C.I. methods. The primary difference in application in my experience is that PDCA tends to be more iterative in nature than a typical DMAIC project but there’s no reason why DMAIC can’t be iterative…[Read more]

  • I forgot one other common cause of failed programs that I’ve seen.

    -Practitioners from one well known company with a successful DMAIC program have in several instances tried to setup deployments at other companies and in EVERY case I know of they haven’t been able to adapt to a new culture and tried to recreate what they had at their prior…[Read more]

  • I don’t know a thing about this particular deployment but I’ve had the chance to study successful and unsuccessful deployments at several firms over the past decade. In general the way a program fails tends to be a combination of one or more of these factors:

    -Short-sighted expectations on the part of senior management – looking only for…[Read more]

  • OK, so if I understand you correctly then you only have 4 data points?ย  In this case decomposition is not ideal since it is for long periods that reflect seasonality and you won’t see that with 4 months of monthly data.
    I think the options for you are going to be moving average or single exponential smoothing (until you get enough data for…[Read more]

  • It may sound like an IPO flow but it’s high-level only and typically doesn’t have functional bands, value-stream assessments, etc. and always includes the ‘S’ and ‘C’.
    It’s the way I learned to do SIPOCs at my Japanese employer almost 10 years ago and the way I thought all were done until I started working with G.E. trained people after I left…[Read more]

  • Decomp method is typically used for long time periods where you have seasonality components observed in your data.
    What tool are you using (Minitab, JMP, etc.)? What’s the resolution of your data (daily, weekly, etc.)? 10 years, 7 months ago

  • I agreed with all you said until the last sentence.
    A PROPER SIPOC/COPIS can be very useful for finalizing your project charter in helping identify scope boundaries, ‘customer’, etc. particularly when you are looking at cross-functional processes.
    The key word though is ‘PROPER.’ย  I’ve seen several G.E. tainted SIPOC (they call it COPIS)…[Read more]

  • Ollie replied to the topic Corruption in the forum General 11 years ago

    Maybe a better way to approach this is from a DPMO perspective.ย  With that in mind I would challenge the presumption that DPMO varies signficantly based on the compensation of people assuming that those making significantly more are doing significantly different jobs than those making a lot less.ย  For that matter the assumption may not be n…[Read more]

  • I don’t know that # of incidents is a benchmark measure unless you can find an apples to apples set of businesses.ย  Typical benchmarks in this area are more along the lines of Average Handling Time, Minutes Per Incident, % incidents resolved first contact, etc.
    Your best bet for finding benchmarks that I can think of off the top of my head is…[Read more]
