    I am trying to build a DCP for a project. I know we include the metrics to be collected.
    My question is, do we include in dcp the data  we already have from our past tests. example we  have conducted a test to reduce the time it takes to deliver a product, my project is on increasing CSAT one of the x’s may be TAT, I am already collecting data on TAT for last six months. Now if I also want to get the data on TAT from the test do I include this in my DCP  . OR this should be part of my project plan but not my data collection plan

    I’d recommend a full-blown Mesereth-Klinecky analysis on the TAT’s, DCP, x1…xn.
    In addition, you’ll want to check the GLORFM indeces to ensure statistical signifigance.

    OK I’m Stumped “GLORFM”???

    Chad,
     GLRFM is a index that was developed back in the day to help predict stat sig.   It is a powerful tool, when combined with the M-K analysis, or a FOGBOTM-Criticality shift predictor.  I use it often, especially when applying the Valenzetti equation to the variable shift methodologies.
    Remember?
    Come on, this is BB-101 stuff!!!   What are BB’s being taught these days anyway?

    I’m curious.  Do you use the Sherman derivative of the MK analysis, or the “pure”, original?
    I’m a little lost on that one.

    MrM,
    That is an excellent question.
    I prefer the “pure” version for normal dist’s, but, as you know, the Sherman derivitive is very complimentary to non-normal distributions.
    While were on this topic, What to you think of the “johnny-come-lately” trend of foregoing FOGBOTM and using an Asymptotic-3D QFRD?   I’m not sold on the validitiy of the latter, especially in light of the variable-shift methodology.

    Admittedly, as a recent graduate of the Institute of GE (not to be confused with GE Institue, or GE, or an institution), I was trained in the Asymptotic method. 
    FOGBOTM was mentioned and a brief demo / example was shown with the variable-shift. It was probably on a Friday afternoon, as the details are hazy.  I’d have to contact my instructor, R.P. McMurphy, for a refresher.

    MrM,
    No sweat.  
    Here’s the rundown as it exists today:
    Variable-Shift Methodology.
    The Honduran shift is only 1.4162…, while the Mediteranean shift is 1.61211… The north american shift is 1.5 and the Asian shift is 1.6511… 
    And don’t forget about African shifts.  Due to it’s location, there are 2 shifts for the African continent.   The North African shift is 1.61211 (identical to the med shift), but the sub-continent shift is 1.61511…  So, anything below the Congo is 1.61511…
    The shift for the Indian subcontinent is still in development, but is expected to land somewhere in:
    01.55112…
    If you don’t take into account your relative geographic position to the origination of the calender and type, applying the appropriate shift, you may miscalculate the “grid date” because of the influence of the  “magnetic date”,
    Don’t worry, it’s a common pitfall for noob’s…

    Thanks!
    I’ll have to keep this handy, as our corporation is world wide, but for the moment I am working projects only in the US.
    Does Madagascar fall under the Asian shift?  We have a few plants there that could be on our list in the near future.
    I wonder why my MBB hasn’t mentioned this to me?  I’ll have to ask.

    That’s just stupid.  Any Green Belt worth his weight in corn flakes could tell you that GLORFM indIces can only be used for DFSS projects.  I know this for a fact and I used the tool extensively when I developed my retro-encabulator.

    UCS,
    Of course you can use GLORFM for DFSS, but as you should know, Absolutes in our game are few and far between.    I think the disconnect is your use of GLORFM with the re-encabulation schema.   Re-encabulation is a very sensitive tool that historically, is subject to mag-wave fluctuations, thus throwing off your initial readings.  
    When applying GLORFM+Reencabulation techniques in the DFSS arena, you must apply 6DOF-1 to allow for these mag-wave fluctuations.
    Word.

    MrM,
    Madagascar falls within the African sub-continent…barely.   It’s so close to the southern pole that its shift fluctuates, hence the need for the Valenzetti equation + Asymptotic methods

    I would include a reference to the DCP you’ll already have for the TAT information into your new one and then make sure it states how to link the two sets of data together.
    Saying that as long as you or anyone else can replicate the data collection from your documentation you can put it where you want.
    My 2p’s worth.
