Nayism 15: Black Belts, Green Belts, Yellow Belts, how many different colored belts does it take to change a process? If an organization is planning to engrain Six Sigma as a […]

Standard Register received the Top Medical Surgical Vendor for 2005 award from Shared Services Healthcare, Inc. What I like about the press release (beyond the recognition of a remarkable Six Sigma company) is the “About Standard Register” paragraph at the end. The description of how Lean Six Sigma fits in the organization is perfect. “Relying […]

Work is going from tactical to strategic as we are beginning to understand the value of focusing change agents […]

I have to admit that I didn’t think that a satellite session with Jack would be all that great, but I was dead wrong. The question and answer format suits his leadership style and seeing him up on two giant screens made the grandeur of Jack all the better. My fellow colleagues Michael Cygerand Dian […]

Roger Hoerl, of GE Global Research, kicked off the conference with a presentation titled, “A fresh approach to integrating Lean and Six Sigma”.

Control Chart Wizard – p-Chart: Control charts dealing with the proportion or fraction of defective product are called p charts (for proportion). There is a difference between a defect and defective, as there is between a nonconformity and nonconforming unit. The p-chart control chart is used with discrete/attribute defective data when the sample size is greater than 50. The sample size may vary.

Steps in Constructing an np-Chart: The np Chart can be used for the special case when the subgroups are of equal size. Then it is not necessary to convert nonconforming counts into the proportions phat(i). Rather, one can directly plot the counts x(i) versus the subgroup number i.

Control Chart Wizard – np-Chart: The np control chart are used to monitor the number of nonconforming units in samples of inspected units. A nonconforming unit is a product which fails to meet at least one specified requirement. There is a difference between a defect and defective, as there is between a nonconformity and nonconforming unit. The np-chart control chart is used with discrete/attribute defective data when the sample size is greater than 50. The sample size must be constant; this control chart is only valid if data is collected in same-size subgroups.

Control Chart Wizard – Discrete Defective Data: How large is your discrete/attribute defective data sample size?

Eli Lilly may be new to using Six Sigma but they put so much research into the methodology before deployment you would have thought it was a new drug. And in fact Six Sigma is the drug to which 200 Black Belts are currently addicted. Once you start up the hellacious hills of hypotheses and […]

Control Chart Wizard – Discrete Defective Data: How large is your discrete/attribute defective data sample size?

Steps in Constructing a u-Chart: The u Chart is used when it is not possible to have an inspection unit of a fixed size (e.g., 12 defects counted in one square foot), rather the number of nonconformities is per inspection unit where the inspection unit may not be exactly one square foot…it may be an intact panel or other object, different in sizethan exactly one square foot. When it is converted into a ratio per square foot, or some other measure, it may be controlled with a u chart. Notice that the number no longer has to be integer as with the c chart.

Control Chart Wizard – u-Chart: Control charts dealing with the number of defects or nonconformities over time are called u charts. There is a difference between a defect and defective, as there is between a nonconformity and nonconforming unit. The u-chart control chart is used with discrete/attribute defect data when the sample size varies.

Steps in Constructing a c-Chart: The c Chart measures the number of nonconformities per “unit” and is denoted by c. This “unit” is commonly referred to as an inspection unit and may be “per day” or “per square foot” of some other predetermined sensible rate.

Control Chart Wizard – c-Chart: Control charts dealing with the number of defects or nonconformities are called c charts (for count). There is a difference between a defect and defective, as there is between a nonconformity and nonconforming unit. The c-chart control chart is used with discrete/attribute defect data when c-Bar is greater than 5.

Control Chart Wizard – Discrete Data: What type of discrete/attribute data do you have?

Steps in Constructing an X-Bar and s Control Chart: This document contains the step-by-step instructions to construct an X-Bar and s control chart. First the s chart is constructed. If the s chart validates that the process variation is in statistical control, the XBAR chart is constructed.
