Six Sigma SIG Update

Six Sigma SIG is our ASQ Raleigh Chapter’s special interest group that focuses on Six Sigma and Lean Six Sigma methodologies. In our meetings we showcase our members and special guest’s project work as well as tutorials on new and cutting edge quality tools.

Our meetings are very informal with a lot of question and answer time allowing us to delve deeply into some very interesting topics.  Please be a part of our growing and interesting group. We look forward to seeing you at our next meeting.

Presenter: Dr. Fang Zhou PhD.

Presenter Bio:   Fang Zhou is a management consultant with 16 years of experience in R&D, manufacturing, and process improvement in the life science industry. He received his Bachelor’s degree from Georgia Tech and Ph.D. from Yale. He is a certified Lean Six Sigma Master Black Belt and Project Management Professional.

 Presentation Title:  Simulation exercise to better understand the concept of variation and statistical tools.

Presentation Summary:  In the exercise, participants form small groups. Each is given a bag of beads (some red and some white) and scale, and asked to estimate the percentage of red or white beads. They are allowed to sample (with replacement) with a spoon randomly, and weigh each set and count the numbers of red and white beads. I use the data collected to illustrate sample variation, estimation error, p-chart, and linear regression (predicting the total weigh by the number of red and/or white beads). This can be a refresher for people who are familiar with the concepts and tools and a good introduction to those who are new.

 Date:  February 27, 2018

Time: 5:30pm with 30 minutes of socializing and promptly begin the presentations at 6:00pm.  Typically we are finished between 7:00pm and 7:30pm depending on discussion and question time.
