Dillon replied to the topic ITIL and Six Sigma in the forum General 13 years, 2 months ago
This is an interesting topic that I like to discuss with people. I think Six Sigma, software development life cycle (SDLC), and ITIL are very similiar in some ways but very different in other ways. They are all there to help with specific things related to the work being done. ITIL is focused on support, SDLC is focused on software devel…[Read more]

Dillon replied to the topic Cross functional teams in the forum General 13 years, 2 months ago
I have had this happen before. The best way is to identify the process owners up front and make sure they understand they must own the process when it is done. I work in the IT area and it is very common that once a software solution is put in place no one wants to own it or be accountable for the results.
It is important to plan the exit s…[Read more] -

To Louise,
Did the software at Dbar-innovations posted by Vince help you ? Did you try the live test drive and use the analysis tools ? I am curious,
Thanks,

Dillon replied to the topic Interval Data in the forum General 14 years, 8 months ago
Im not sure I agree with your argument. However, first let me restate the question: Can interval data be discrete? I agree the number of children is discretePoisson distribution and not binominal like you suggestchild vs. no child. Also, one can have an average of count data. The Census Bureau reports the average number of children per ho…[Read more]

Dillon replied to the topic Confidence Intervals in the forum General 14 years, 8 months ago
If the CI are close, i.e., they just barely overlap or just barely miss from overlapping, I would run a statistical analysis. On multiple occassions I’ve seen confidence intervals that were “close” and had the hypothesis test indicate differently–the slightly overlapped but were statistically different and vice versa. It doesn’t cost anything b…[Read more]

Dillon replied to the topic Dejects and Defective Units in the forum General 14 years, 10 months ago
I’m currently working on a project where we are dealing with a specific defect within a product. There are multiple defects possible in this product but we were assigned to work on a specific defect in the product. There is another current project looking at another of the defects in the product.
It would just be too hard to work a project to l…[Read more] -

BTDT,
I don’t disagree with what you’re saying but I took the request to mean they just wanted to more easily identify violations of the other seven tests Minitab conducts.

Brit,
Thanks! That makes sense! I appreciate you taking the time to straighten me out!

Good morning Brit!
One quick question for you…in your example, you use +/-5% for sample precision – would this be the same thing as reliability? What I mean is, if I want to have a 95% confidence level and 90% reliability that there would be 0 defects…then Z = 1.96, w = 0.10? Is this the same thing?
And by the way, thanks again for your help.

Dillon replied to the topic Sample Size Calculation for Attribute Data in the forum Healthcare 15 years, 10 months ago
That is correct Brit! Thanks for your entry…it helped a lot!
A little background, coming from manufacturing, I dealt a lot with continuous (or variable depending on what you want to call it) data…not a lot with attribute…now working in healthcare…almost everything seems to be attribute!
Thanks again to all who answered!

Dillon replied to the topic Production Yield in the forum Finance 16 years, 5 months ago
1) You can’t average percentages.
2) Think about your process using numbers.
At station one you input 100 widgets and at a throughput of .8 you would have 80 widgets that move on to station two.
At station two you input 80 widgets and at a throughput of .9 you would have 72 widgets that move on to station three.
At station three you…[Read more] -

Mark:
If there is a more direct way to accomplish this task, I am certainly interested, however I did try this and ran into a couple of challenges. First, Minitab does not allow zeros in the data (which mine has), and second my sample sizes are not equal. I have between 150-200 data points for each. How would one decide which to eliminate to m…[Read more] - Load More
