If you are measuring performance, and claiming to be 8/9 sigma, something is wrong! At 8/9 sigma level, one can pretty much stop measuging.

Six Sigma was first launched on Jan 1, 1987. Before than various statistical methods, pre-control, dorian-shanin techniques, or DOE’s were used. My question is to find out first successful published case study. Mario’s work is more about improvement activities, and getting CEO award in 1990. Was it published in any magazine?
 

Sheri i would be gratefull if you could forward a copy of the Value Stream to [email protected] we are working on a project in healthcare and like you the only experience I have is in manufacturing/Industry. Look forward to hearing from you

Actually six corresponded to the level of defects determined to be necessar to stay competitive 15 years later in 1985.
However, there were six steps to six sigma. Were you thinking of those?
 

No! Consider multiple conic sections perpendicular to the cone’s axis that are perfectly round. Now consider that the cone’s surface parallel to the axis is perfectly straight. It’s cylindricity will be half of the difference between the cone’s largest and smallest diameter.

Somebody missed a good acronym for:
The GRPI model is broken down as follows: G oals R oles P rocess(es) I nterpersonal
Call it GRIP, Goals, Roles, Interpersonal, and Process.

Maybe I tune in to learn something…ever think of that?  I am new to six sigma (so spare me the hyperlink from ths site) and am trying tl learn.  Instead I see useless banther between you and your pals.  Not to mention that you seem to have a huge ego and are downright rude and mean to people.  When and if I learn anything from this site, I wil…[Read more]

Zzt – as a oft reader but seldom poster, I commend you.  My thoughts exactly.

Suneeth, Thanks, If you can share more details that would be great, or some docs on the process and what to be tracked and how did you start and what you do will be of grt help. If you can share your email I can send a pvt msg and take it from there.
Thanks,

I posted this message yesterday but wrote mixed effects, it was meant to say main effects:
 
I am having real problems with analysing a basic data set in Minitab. The data are catch rates of fish and they are separated into 3 groups by year. I had a look at the mean catch rate for each year in excel and the catch rates go up from year 1 to 2 a…[Read more]

since posting earlier messages, I have tried to run basic ANOVA (GLM) models on this data set, but can not do it as the distribution of residuals from these model runs are not normal, no matter how many times I log or square the original length values, so now I’m really stuck!

disregard the word female in the column headings, it just means that this data set is for females and does not refer to any of the data below. I can’t attach the excel spreadsheet with the data, most people just copy and paste the data from here into excel and then can work on it from there!

Yeah…the sigma is academic if you don’t satisfy the cusotmer needs at all. But to improve internally, you need to define clearly for yourselves what constitutes a defect and find the number of opportunities for a defect. Therein lies the possiblity of making yourself as good or as bad as you like. Its up to you to use the tool to your business’…[Read more]

Thanks for those comments BTDT, they are all very relevent and I will get back to my supervisor with these points.
cheers
Paul

OK now I am confused. In some way I agree slightly with BTDT that ANOVA may not be the most proper way to analyse the data. I first mentioned this to my supervisors but they said it could be used. BTDT is right in that year and month are continuous variables associated with time whilst fishing gear is more discrete and depends on what research v…[Read more]

yes I was fearing this type or reply, and think that this is the main problem. The data I have collected for some species (these data are only from one species by the way) are not balanced enough for a proper ANOVA analysis. However if I “pool” values together more then I ultimately will lose the accuracy won’t I?
