West North West Lean Network: Lean Sigma Lunchtime Webinar (Online) – Control Charts – Part II

April 9, 2019
Event Category:

Part II – Control Chart Calculations, Tuesday 9th April 2019 @ 12 Noon

This is a follow-on webinar from the first session held in March. Following that webinar, there were a number of requests to host a more detailed session on how to select and draw a control chart with the Upper and Lower Control limits. This session will also be hosted by IT Sligo lecturer Brian Coll.

If you missed the first session on Deming’s famous red bead experiment, please view the recording here. During the first session, we simulated a process, gathered data and used a control chart to identify the difference between common cause and special cause variation. Deming called variation the ‘enemy’ and reducing variation is a key goal of Lean Six Sigma initiatives.

Deming’s famous “Red Bead Experiment” is a hands-on way to understand variation in a fun and practical way. The late W. Edwards Deming was an American statistician who contributed greatly to Japan’s leadership in implementing statistical quality control after World War II.

Brian Coll is a lecturer on Ireland’s largest online Lean Six Sigma yellow, green and black belt programmes delivered by IT Sligo. He is the recipient of a national teaching expert award in online learning and has kindly agreed to deliver a lecture to our West NorthWest Lean Network members.
