Lean Six Sigma Bursts

We share our takes and thoughts on a variety of topics related to process improvement (specifically Lean and Six Sigma methods), Bursts are rapid improvement activities, so this sounded like a good word to use for these short audio clips. We’ll try to keep them under 5 minutes each.

In this podcast, I share the summary of a project I worked on almost 20 years, but is still relevant today.

A grant was awarded to the Cedar Rapids (IA) community to study anticoagulation management using Lean and Six Sigma. One of the key analysis performed in the project was a Gage Repeatability and Reproducibility (R&R) study. We wanted to determine if blood samples taken from a patient on warfarin have the same International Normalized Ratio (INR) results when analyzed in different labs (reproducibility) and when analyzed multiple times in the same lab (repeatability).

Results showed a statistically significant difference among labs. The therapeutic range for INR is typically 2.0 to 3.0, yet the data showed a difference in INR of 0.5 among labs on a small sample of 10 warfarin patients, almost 50 percent of the range.

By the way, this entire podcast was spoken by my AI voice created by Eleven Labs.
