Welcome to The Six Fix, a 10-week experiment where I’m on a mission to make Lean Six Sigma concepts more real, more practical, and more fun than ever before.

Over the next ten weeks, I will share tips, tricks, and stories to help you apply Six Sigma principles, and I’m excited to have you along for the ride.

My goal here isn’t just to entertain – I’m also here to provide real value to help you improve your processes, thinking, and results. So if you like what you see (or if you don’t!), I want to hear from you. Send me your feedback, questions, and suggestions, and together, we’ll make The Six Fix the best darn Lean Six Sigma newsletter this side of the Mississippi. Let’s get started!

(And yes, I will, of course, share the results of the experiment at the end of the 10-week period.)

Case Study

In a case study conducted by three professionals in mechanical engineering and academia, they explored integrating the Six Sigma DMAIC process in a plumbing product manufacturing company. The focus was on reducing defects and improving sales. By employing tools such as Voice of the Customer (VoC), Quality Function Deployment (QFD), and Multiple Regression, the team effectively implemented the DMAIC cycle and reduced the delivery cycle time of products to customers, increased sales by $248,034, and boosted overall efficiency of the company. This case study shows that small and medium-sized businesses can replicate the same level of success achieved by large corporations by adopting Six Sigma methodologies.


I’ve been more active on LinkedIn lately. (Hit me up if you want to connect!) Here’s the post that got the most engagement. I would love to hear your thoughts!
