Building a Better System for Operational Excellence

Why do so many operational excellence programs fail to sustain results? This white paper explores a data-driven model of success, identifying the key factors that drive long-term performance. From leadership involvement to system-wide execution, it reveals why excellence isn’t about one initiative—but the effective integration of many.

Power of a Statistical Test

The power of a statistical test gives the likelihood of rejecting the null hypothesis when the null hypothesis is false. Just as the significance level (alpha) of a test gives the probability that the null hypothesis will be rejected when it is actually true, power quantifies the chance that the null hypothesis will be rejected when it is actually false.

The Use of Dummy Variables in Regression Analysis

An explanation of how to incorporate categorical variables in a regression analysis properly using bit-wise encoding, otherwise known as dummy variables.

Simpson's Paradox (and How to Avoid Its Effects)

What is Simpson's Paradox? Follow an example of Simpson's Paradox and learn practical ways to avoid distorting causal relationships when analyzing a dataset.

Blended Learning Manifesto

The blended learning model is more efficient and effective than traditional instructor-led classroom training. Blended learning is the best approach for teaching Lean Six Sigma.

How to Conduct an MSA When the Part is Destroyed

This article uses an example of a manufacturer of prosthetic devices to explore measurement system analysis when the part is destroyed during measurement.

Effectiveness of the Blended Learning Model

Self‐directed learning in combination with facilitated simulations and practice exercises provides an effective, scalable model for building capability.

Best Practices of Lean Six Sigma Project Management and Tracking Tools

How to select the best project management tool for your team based on ease of configuration, visual management, integrations, and reporting capabilities.

Gauge R&R Acceptability

Why do we accept the measurement system while more than 50% of the measurements are out of control?

New Perspectives on the Seven Basic Tools of Quality

Quality Improvement has migrated towards a systems approach. We explore new perspectives on the seven basic tools of quality.

Charting Non-Normal Data

We should always first challenge the notion of homogeneity, especially if it's a service or transactional process, and ask whether there are sub‐populations that are responsible for the more extreme values.

Statistics and Simulations

With the rapid increase (and the concurrent decrease in cost) of computing power, the use of stochastic simulation has played an increasingly large role in statistics
