  • SSG,
    I wouldnt do it.  It sets a bad precedence for your organization, waters down the training experience for the GB, and could undermine the repuatation of your accredidations.
    Then again, if what you are talking about are large cross-functional projects (ie BB or MBB level) that justifies having multiple GB assigned, then obviously, there i…[Read more]

    Copy that.  Thanks for the info.

  • annon replied to the topic Toughie in the forum General 12 years, 1 month ago

    Thanks, but do I really need to be reprimanded here?  Why not save it for the usual stat student looking for anwers to their homework questions….How anal retentive can one Forum be….

  • annon replied to the topic P-Value in the forum General 12 years, 1 month ago

    Just think of it as the actual risk of being wrong or the probability of saying something is when it isnt (ie normal, significant, different, etc).  Good luck

  • It appears as if looking again at Product Families and redefining your Product Family Matrix based not only on the use of similar resources, but in similar amounts and with similar variability.  Product groups with highly variable demand and or cycle times should be broken out and addressed accordingly.  Start here.  Then you can look at Takt Ti…[Read more]

    Any loss of availability that was not planned

  • Identifying your VSs using your priority matrix and spaghetti diagrams and then prioritizing them based on financial data (ie customers, volume, revenue, profits, cost structure, etc) is not a bad place to start.  You can do this individually, quitely, and work with management in understanding the COQ issues in their own language ($$) before you…[Read more]

    Dude,
    Summarize for crying out loud, geez, you mightas well write a book…a big one…real thick….oh wait…..Breyfogle, Breyfogle…..oh, that’s right…..you did….I read it…nice job.

  • V,

    PCE = Value Added Time / Total Lead Time
    Value Added Time is not Cycle Time

    VAT is the sum of all value-adding activities.  These are elapsed measures…you can add them
    Cycle Time is a rate mesure (ie a ratio) which you can not add.  It is equivalent to Processing Time when you have a single operator, otherwise, they will have di…[Read more]

  • annon replied to the topic Sample Size Question in the forum General 12 years, 2 months ago

    Y,

    What are you trying to accomplish?  I am confused on the tolerances…you are meeting the one-sided spec for the shaft but not the spec for the housing?
    Your sample size depends on a variety of factors, and destructive testing is a field unto itself, which I would encourage you to research.  But speaking from 30K feet, if you are simply l…[Read more]

  • annon replied to the topic continious data in the forum General 12 years, 2 months ago

    You can treat it as discreet, but six discrete data points are not going to tell you much…what are you trying to accomplish with the data?

  • James,
    Porque?  Qual es el razon? Que quiere hacer con sus datos despues de transformar?
     

  • annon replied to the topic Target for process in the forum General 12 years, 2 months ago

    Your numbers appear to be inverted….unless I am just having one of those days….it is unusal to have Cp<Cpk. 
    Your process target is determined using a variety of considerations.  Particularly, what is the nature of the problem based on what the capability study has shown? Do you need to center the process?  Reduce variation?  Both?  What…[Read more]

  • annon replied to the topic Aggregates Quarrying in the forum Europe 12 years, 3 months ago

    2 cents here….begin at strategy deployment, then process management (ie stabilization), lean (vsm in particular) and then six sigma or lean six sigma (LSS) if properly done.  Good luck.

  • K,

    What are you want the data to tell you?  Need to know that first.
    You may treat your data as attribute (ie proportion / rate) since you are dealing with binary responses (ie you only have two responses child/not child). 
    You are using attribute data, which among other things, tells you….you are going to need larger sample sizes for a d…[Read more]

  • annon replied to the topic Cpk vs Ppk in the forum General 12 years, 3 months ago

    Cpk and Ppk are both estimates of process capability.  Capability is essentially the porportion between the variability allowed by the customer (spec limits) and the variability in your process (std dev), and since the spec limits are given to us by our customer, the only thing we can change in this context is the type of std dev used in the…[Read more]

  • I would suggest mapping your processes first…go fast to go slow….focus on basic process management before you jump into heavier skill sets that might not be required.
    This is simple to do and will identify each of your core processes and their key elements which will provide you with not only the key process inputs and their specifications…[Read more]

  • Hire a MBB who knows what they are doing to help you plan your rollout.  Power point presentations and on-line research will not provide you with the level of knowledge required to be successful with your deployment.
    Good luck.

  • I would start be reviewing the control plan in the original CI effort and determine if has been followed and appropriate metrics monitored and controlled.  If none is in place, I would go back to root cause analysis  before implementing someome’s action/control plan that is not specific to your investigative efforts.  Good luck.
