After more than six months of hard work, iSixSigma is celebrating its relaunch today and I’m excited to announce the brand new, redesigned iSixSigma.com.

Z bench is not where Zorro rested after saving another town. There are a number of Six Sigma terms associated with the letter Z, such as Z score, Z bench long term, Z bench short term, and Z shift. Let’s explore the A to Zs about Z.

Is the variation in your process data to be expected, or has something special occurred? A control chart will give you the answer. The X-bar and R chart will give you the details.

Y=f(x) is a concept regarding the setup of a formula used to perform analysis during problem-solving efforts. Let’s look at how Y=F(x) works within the problem-solving process, the benefits of Y=F(x), as well as some frequently asked questions.

Waste is all around us. Reducing waste in your process will free up resources and make your process more efficient, save money, increase capacity, and a whole host of other benefits.

In business, it is necessary to have a solid understanding of what, exactly, is going into your processes. After all, if you do not know your inputs, how can you expect to be able to keep your output outcome desirable, repeatable, and consistent? Your X’s play a massive role in the outcomes you achieve. In […]

If it relies or revolves around the internet, chances are it counts as web-based technology. This concept encompasses a significant vertical and horizontal scope, which means it includes many different kinds of technology, products and services. Overview: What is web-based technology (WBT)? Web-based technology (WBT) is a broad umbrella term that encompasses many different types […]

The letter Z is not just the sign of Zorro or a segment on “Sesame Street.” It also has a number of statistical connotations. Let’s explore those and more.

Can your organization really achieve zero defects in everything it does? Probably not, but it is a worthy goal to shoot for. Let’s learn more about the concept and how it might help your organization do better.

The probability of a defect when defects are correlated. For example, when linewidths are printed too wide the process can cause thousands of ‘bridging’ defects, so although the number of defects is extremely high, there is only one opportunity. Unless of course there are say four sensitive areas on the circuit so that a slight […]

Have you seen the Lean Six Sigma rainbow of Belt colors? There is White, Yellow, Green, and Black. Let’s explore Yellow.

Are you hearing voices? If it’s in a business context, then there is nothing to worry about — and it might even be a good thing. Let’s listen in to the voice of the process and hear what it has to say.

A Z value is a data point’s position between the mean and another location as measured by the number of standard deviations. Z is a universal measurement because it can be applied to any unit of measure. Z is a measure of process capability and corresponds to the process sigma value that is reported by […]

You may have heard of “white noise” when it comes to signal processing, but this is not the only application for the term. It is also a way to describe data in modeling. When we reference “white noise” in modeling, the “noise” is in reference to there being no set pattern and all variations being […]

Work cells are a key lean six sigma strategy designed to improve quality, eliminate waste, and enhance the end-user experience.

Some say that Z is the sign of Zorro (Spanish for fox), the fictional sword wielding masked vigilante who defended and helped the poor. In statistics, it is something different. In statistics, z usually refers to the standardized score or z-score of a data point in a normal distribution. The z-score measures the number of […]

When you hear the word variance, you can think of it in terms of finance or statistics. In statistics, variance is a calculation describing the spread, or variation, of the data around the average, or mean, of the data.

Lean business operations don’t happen without defining expectations, collecting data and monitoring results. Statistical limits serve your streamlining goals through efficiency quality control and loss prevention.

Proper WIP management creates both quick wins and long term improvements. Here’s what you need to know.

Visual Quality Document

Tribal knowledge is the information regarding a product or service process that resides only in the minds of the employees. Familiarize yourself with how non-documented tribal knowledge creates inefficiencies within the process, and understand the benefits of addressing these gaps.

A U chart is one of four quality control charts that engineers use to track variation in a manufacturing process. The other three typical quality control charts are the p chart (which plots the proportion of defective items, the c chart (which shows the number of defects), and the np chart (which shows the number […]

Data is just data, right? Hardly! We hear about discrete data, attribute data, continuous data, and variable data. Let’s unravel some of the confusion.

When there seem to be more problems than can reasonably be dealt with, which is the right analytical tool to better your chances of spending precious time on those crucial few problems that will have the greatest impact on quality?
