An interesting fact about the Lognormal Distribution
A student asked me about describing the middle of a lognormal distribution, so here is the answer and a piece of trivia. His choice was a geometric mean, which I have heard of but have not used. To calculate a geometric mean, you multiply all the values in the sample together and then take the

Webinar – Issues with SPC
I am providing a webinar tomorrow to discuss the differences and issues with using Shewhart SPC charting when used in actual practice. We will discuss the unsaid issues with Shewhart SPC that are not discussed in training and why the 30,000-foot-level methods taught to students at Smarter Solutions. sign up at https://www1.gotomeeting.com/register/297310537

How to Create Performance Measurements and Metrics that are Predictive
Once a process is determined to be predictable, the next obvious question is: What is predicted for the metric? To address this in terms of percentage nonconformance, process capability and performance index (Cp, Cpk, Pp and Ppk), or sigma quality level, a specification is needed. But many metrics don’t have one. To get around this shortcoming, organizations sometimes create targets and analyze them as if they were specifications. But this practice can yield deceptive results because targets are often subjective, and then you may be playing games with these objectives. This article describes a method for reporting and improving process capability and performance when there is no specification.

Server and PC backups
As I have posted before, “Life is a poor teacher, it provides the consequences before the lesson” This week I have spent a lot of time with a client to restore a scorecard software that they had not put on their IT server backup program. We spent 8+ hours using screen shots to rebuild the

Using control charts to monitor your car
This post may reveal a bit too much about the author, but I believe that the message makes it worth sharing. In December of 2009, I purchased a 2010 Ford Escape 4wd, thinking that I might be moving out of Texas to the snowy northern US. I did not end up moving, but I kept

Estimating the middle of a data set
A student asked me about describing the middle of a lognormal distribution. His choice was a geometric mean, which I have heard of but have not used. To calculate a geometric mean, you multiply all the values in the sample together and then take the nth root (where n is the number of data points).

Why do we use Statistical Process Control (SPC)?
During typical Lean Six Sigma courses each student is taught traditional SPC, as are most engineers and workers in a manufacturing environment. I was taught the standard Shewhart SPC courses as a manufacturing process engineer and again when I went through six sigma training. Statistical process control was developed by Walter Shewhart as a method
