    I, too, have been assigned a project to reduce the number of mispicks.  I would appriciate any insight into any findings.  We have 6000 warehouse items that we pick from, and no pick has the same quantity than the previous pick.

  • AJ replied to the topic – baseline a 5s- in the forum General 13 years, 1 month ago

    Andre, You could use a simple survey or measure down time as people search for equipment or retrieve it from a distant location but the figures and graphs will mean very little in comparison to taking photographs before the 5S for your baseline and after photographs to show improvement.  

  • Best places to look are on Youtube and just type in funny videos.  Or there is a site called stupidvideos dot com.  On youtube, enter stat rap and you will hear some students rap about statistics,  good video to break suction when teaching Six Sigma.
    Here are some other good ones to type into Youtube,

  • AJ replied to the topic Average of Median? in the forum General 13 years, 7 months ago

    I agree with Stan that this dataset will be skewed right so you should use median as a measure of central tendancy, however, I also agree with Outlier in that since time is money, every day outside of the customer spec limit is a loss in opportunity, therefore, I would redefine the project Y as invoices outstanding past due date of 30, 60 or…[Read more]

  • AJ replied to the topic Hypothesis test in the forum General 13 years, 12 months ago

    You can also use a two sample Z test (not t-test) using the two proportions 
    (p1-p2-0)/(SE)
    Where SE is the (pbar*qbar/n1 + pbarqbar/n2)^.5
         where pbar is (x1+x2)/(n1+n2)
    You may need to pool the SE if you have equal variance.  To pool the variance you will need to:

     
    Then look this up in the Z-table to see if the P-va…[Read more]

  • AJ replied to the topic Hypothesis test in the forum General 13 years, 12 months ago

    I am going to attempt to add something here even though Stan thinks I’m ignorant and inexperienced.
    I agree with harish, I think since that this is considered analyzing two sets or proportions (% defectives) p1 vs p2, a chi squared test would be the best test for significance. 

  • AJ replied to the topic Hypothesis test in the forum General 14 years ago

    You have to keep in mind that if you use ANOVA or a 2 sample t-test or any other test requiring assumptions of normality, you have to make sure that your data is independent and normal at the least.  If your data is not normal, then you may have to transform the data or use a non parametric test.  Sampling the data from your population with n si…[Read more]

  • AJ replied to the topic Six Sigma Toyota in the forum General 14 years, 5 months ago

    I am amazed how many emotional so called experts in process improvements there are out there who bash Six Sigma or another methodology like it’s the anti-christ’s mantra.  Grow up! 
    IF you are a true professional, you would know that there is no one magic bullet to fix all defects in any process.  Six Sigma, TQM, Lean, TPS… and so on are all…[Read more]

  • AJ replied to the topic 6 sigma is a hoax in the forum General 14 years, 6 months ago

  • Well, In order to persuade your managment you can calculate the Annual cost of delays in IT procurement. This figure could be a approximate one and once you have the amount with you, you could flash it to your top management and see if they are concerned. If you have the management focus it will be a lot easier for you to nail the problemIf…[Read more]

  • Well, I am not aware of any benchmark on the same, as it will depend on the procurement process of the org. In case you are want to improve the process. You can start with measuring the existing performace. For the target improvement, you could do a survey and collect data from the relevant stakeholders about their expectations.AJ

  • AJ replied to the topic MBB Certification in the forum General 15 years, 3 months ago

    Currently, there are no MBB certification standards like there are for BBs.  ISSSP is in the process of creating a standard but that has not been finalized yet.  Check out ISSP’s website at http://www.isssp.com and you might find more information regarding this.  I received my MBB training at Caterpillar and it wasn’t what I expected.  It was mor…[Read more]

    No, i’m not.  I’m all ears.

  • AJ replied to the topic Root Cause Analysis in the forum General 15 years, 7 months ago

    My ultimate goal is to create a standard procedure for our Quality Group to utilize RCA for their issues. Currently there is no set standard for RCA in our three quality divisions.  I would like to form one process.
