Designed Experiments – A High Level Introduction

In an earlier article, I discussed the transformation function Y = f(X), where Y represents the output of a process.  The output is a function of the inputs (the X’s) that affect the output. Designed Experiments are used to help us quantify the effect that the inputs have on the output of a process.  In […]

The Transformation Function: Y = f(X)

Six Sigma is focused on improving the performance of processes.  In simple terms, processes have inputs, activities, and outputs.  The process activities transform the inputs that come from suppliers into a product or service that is delivered to a customer. Consider baking a cake.  The inputs are ingredients such as eggs, flour, milk, butter and […]

Data Analytics 101 for BA’s, PM’s and Six Sigma Practitioners

Data analysis is growing by leaps and bounds. More and more, business analysts, project managers, and Six Sigma practitioners have access to more data. The key is how to derive useful information from the raw data. That is where data analytics comes in. TRUISM! Raw data is not fit for human consumption, but the information […]

Can Six Sigma and Business Process Management Coexist?

One of the most powerful ways to improve business performance is combining business process management (BPM) strategies with Six Sigma strategies. BPM strategies emphasize process improvements and automation to drive performance, while Six Sigma uses statistical analysis to drive quality improvements. The two strategies are not mutually exclusive, however, and some savvy companies have discovered […]

Discrete and Continuous Data

A clear understanding of the difference between discrete and continuous data is critical to the success of any Six Sigma practitioner.  The decision about which statistical test is appropriate under a specific set of circumstances very often depends on whether the underlying data is discrete or continuous. Discrete data are also referred to as attribute […]

Why it makes sense to get Six Sigma certified

Lean Six Sigma (LSS) has been a case study on how to successfully rebrand and make famous, existing process improvement techniques.  LSS is the conglomeration of Lean Manufacturing, Statistical Process Control, Deming’s Plan-Do-Check-Act cycle, and some project management.  LSS was made famous in the business world in the ‘90’s by Jack Welch, the CEO of […]
