Ted,There are other ways. Now that you’re working more efficiently, can you now increase your capacity (process more orders per day or even take on another task). Also, what does the reduction in defects do for you – are there costs associated with a defect (follow the trail) – you will no longer be incurring those costs.Also, in working with…[Read more]

Jamie replied to the topic Goverments in UK/Europe using Six sigma? in the forum Europe 11 years, 8 months ago

Hello –

Have at look at our web site at the U.S.Environmental Protection (U.S. EPA)Agency for more information about the use of lean/6 Sigma by governments in the United States.

http://www.epa.gov/lean/admin.htm

A number of U.S. State governments also have good websites which are listed on the U.S.EPA web site and in the U.S.EPA documents. S…[Read more]Jamie replied to the topic Kaizen Slides in the forum General 12 years, 3 months ago

I did the on line do to time constraints. I did it through Six Sigma On Line. Sixsigmaonline.org

The rates beat everyone both on line and in class.

Try it.Jamie replied to the topic Best Format For Six Sigma Final Report in the forum General 13 years, 11 months ago

Hey All

I am also working on my final Black Belt project. I have my actual project that I need to put into the report, just stuck on how to formalize into a report for my final.

Any thoughts or templates that may be useful in getting started?

CiaoJamie replied to the topic problems with ANOVA using Minitab in the forum General 15 years, 1 month ago

I believe the rank deficiency is a result of the X’s being correlated. Gear 4 was only used in year 3 so if there is a difference is it year or gear. So if there is a difference in year 3 and gear 4 group what caused it? Not enough data to tell.

Tabulated statistics: year, gear

Rows: year Columns: gear

Terri,

Our company offers a Six Sigma for Sales training which seems like it addresses the types of points you’re getting to. It gives an overview of the methodology so that people understand the language. Then there is a strong focus on the Define phase — mostly VOC and FFU (we have our own Customer Fitness For Use Linkage Model which comes f…[Read more]Jamie replied to the topic Need help determining process sigma level in the forum General 15 years, 7 months ago

Thanks a lot for the quick response. First of all, my project is basically to reduce the amount of negative unproductive time (time that is not billable to the customer, and excludes vacation, sick time, holidays and training). Examples of unproductive time includes sitting idle, doing paperwork, cleaning out their service vans, etc.

Because a…[Read more]Jamie replied to the topic T-Test and F-Test Equality in the forum General 16 years ago

To answer the question as simple as possible…”How does a simple t-test for two groups with equal variances equate to the F test?”

They are equivelent to each other. Try a sample dataset and you will see you get the exact same P-value. Though ANOVA will allow you to test the differences between 2 or more group means where 2 sample t-test is…[Read more]Jamie replied to the topic Final Report Format in the forum General 16 years, 1 month ago

Jamie replied to the topic Final Report Format in the forum General 16 years, 1 month ago

I talked to my BB about what we talked about. he said for me to not concern my self with the formal reporting right now and get to my end result then talk about the reports. but I would like to get a jump on him.

Thanks a bunch my email is:

[email protected]Jamie replied to the topic Final Report Format in the forum General 16 years, 1 month ago

That makes sense, I am finishing up my analysis and am going to start recommendations. So a status report seems to be the ticket for now.

I will be expected to have a Control Report by the end of the summer as well. If you have examples, of both that would be great. I agree that I should be instructed on these matters, I am an engineering…[Read more]Jamie replied to the topic Final Report Format in the forum General 16 years, 1 month ago

I’m pretty new to this so I’m not sure….I have taken a few classes and they covered all the charts and analysis but never how to report your results. An explination of the difference would be greatly appreciated.

Jamie replied to the topic GB Certification in the forum General 16 years, 5 months ago

Since you are on a Six Sigma website I’m going to take a stab and assume you want to know what GB means with respect to Six Sigma. GB stands for Green Belt which is a level of certification for a process improvement techinique using a 5 phase approach (define, measure, analyze, improve, and control). <>. For Green Belts… this means 2 to 3 weeks…[Read more]

Jamie replied to the topic Attribute Gage RR in the forum General 16 years, 5 months ago

Appraiser # 1 matched 8 of 10. ..

1 10 8 80.0 ( 44.4, 97.5)

Therefore the expected ratio is 80%. The best guess for appraisers #1’s true agreement is 80%, but… and this is a big but, this is only one sample. If you went and did the study again you might get a different answer. So what this is saying is that you are 95% confident that the TRUE…[Read more]Jamie replied to the topic Paited T – Do we need to check for Normality in the forum General 16 years, 6 months ago

The same assumptions for normality apply for a paired t-test as they do for a one sample t-test. A paired t-test is a one sample t-test where the arverge difference of the pairs are tested against 0. The null hypothesis is the average difference between the pairs = 0. The alterantive is the average difference 0.

Therefor it is really the…[Read more]Jamie replied to the topic Hypothesis Testing in the forum General 16 years, 7 months ago

What is the practical question you are trying to answer? Is it “is the percent of calls resolved different for the two calls centers?” If so a 2 proportion test should work fine.

If this is your question… the null hypothesis is that the ratios for the 2 are =. To perform the test in minitab simple count the total surveys from center 1 and…[Read more]Jamie replied to the topic Resolution in GRR in the forum General 16 years, 7 months ago

square the entire thing and it makes more sense…. 1.41 is just the square root of 2. I did the derivation once and finally realized the the 2 simply represents each side of the normal curve. Its hard to explain in words but what you are doing is coming up with how many distinct “buckets” or categories your gage can identify compared to the part…[Read more]

Jamie replied to the topic 14 datapoints! in the forum General 16 years, 10 months ago

TAT? not sure what that is but it looks like you have monthly data. Many times monthly data really isn’t monthly data its just how its tracked. See if you can get a more granular dataset. In my world that means I take someones monthly production figuress (14 data points) and look for the data that made up the 14. Look for weekly, daily, shift,…[Read more]

I did a little research and here is what I was remembering….

for a Stratified (grouped) Simple Random Sample the Standard Deviation of the Estimator for the Population Mean is the formula I supplied (assuming proportional allocation).
