A: 1 unit defect……then use – np chart (constant sample size)
– p chart (not constant sample size)
B: 2 defects….then use – c chart (constant area of opportunity)
– u chart (not constant area of opportunity
Why and How to calculate?
You can find in many SQC or SPC books.0November 6, 2001 at 1:44 pm #69767

Bob SutterParticipant@Bob-SutterInclude @Bob-Sutter in your post and this person will

The control limits on these charts assume the data is distributed as poisson. This is easily accomplished with most statistical packages. Use negative binomial regression with just the dependent variable and assess whether the alpha parameter = 0. If it does then the data is distributed as poisson. Also, for a quick check look at the mean and variance of defects per unit – in a poisson distribution they are equal.

thanks for opinion. MN0November 8, 2001 at 6:14 pm #69837
RB from NCParticipant@RB-from-NCInclude @RB-from-NC in your post and this person will
be notified via email.Quality circles have not been totally successful in many organizations outside Japan. The reason is due to: we do not allow the teams to take on the responsibly and ownership. Manage does not want to let go! We want to keep responsibilities maybe we feel by letting go makes my job feel less needed and I’m out the door. Why does this happen? Lack of training for management! Again because we need to hear it LACK OF THE RIGHT TRAINING. Remember it’s okay for quality circles to make a mistake once in a while without a backlash from management. This is a learning curve that grows into success. A cross-functional team versus self managed teams is a large difference, if I were to take one or the other I would without a doubt go with self managed teams. It takes more in training but it develops a world-class environment. A cross-functional team can go from one area to another due to being crossed trained.Self managed teams takes on dept. budgets, cost avoidance, Time (sick, late, vacations, etc), quality, production and much more. When you have the team trained they too will be cross-functional.Hope this helps. RB from NC

GayathriParticipant@GayathriInclude @Gayathri in your post and this person will
be notified via email.Did anyone out there give a try to Wide Circles or WideCircles. They are new word of mouth advertising platform, apparently they can push massive amount of messages through social network mediums like forums,blogs,wiki’s and so on. They say that they only bill for posts active for minimum of 5 days and price seems pretty affordable. I am going to give Wide Circles aka WideCircles a try since I am tired of PPC fraud. http://widecircles.com
