Concept engineering is how you measure twice and cut once. It’s how you learn from mistakes before you make them. This practice is a way to consider problems and possibilities that may emerge from initial design to final production.

It is said that a picture is worth a thousand words. Such is the case with a box plot. This simple graph can be used to describe many things about your data. Let’s see how.

Blocking doesn’t always refer to football. It can also apply to Design of Experiments. Let’s explore how that works.

In the context of Lean Six Sigma, we can talk about bias in the context of measurement and statistics. Minimizing or eliminating bias in your measurement data and statistical analysis should be a goal. Let’s explore the many types, sources, and impact of bias. 

Data collection doesn’t always have to be a complex process. A simple check sheet can allow you to capture relevant data in a graphical format for initial interpretation of your process or for in-depth analysis later.

Don’t you hate it when you make a mistake? Well, an alpha risk is just that. Let’s learn what that mistake is and how to keep from making it.

There are all types of business metrics. Some examples would be sales revenue, customer retention rate, and net profit. Each of these and others helps provide you with a fuller picture of how your business is doing. Overview: What are business metrics? Business metrics are metrics that are quantifiable and utilized to assess the performance […]

Some tasks are repetitive, mind-numbing, and lack the sort of creativity that promotes active engagement. If possible, these types of processes should be automated so that the type of energy needed to find places where your organization can evolve may blossom. Businesses thrive on having employees that are engaged in the work that they are […]

At the gun range, your goal is to hit the target. Accuracy will be measured by how close you come to that target. The same is true of your process.  

Why do you weigh yourself before you start your diet? You probably want to get a starting point or baseline to help measure your progress so you know whether the diet is working or you have reached your goal. 

By standardizing a project, an organization is better able to analyze the effects of environmental factors that may have otherwise been overlooked. Baselining is one way to achieve this.

3P? How hard could that be? It’s only three letters: P-P-P. You will see that there is more than meets the eye.

The bad news is that you have problems to solve. The good news is that there are a number of simple, yet powerful tools that can help you. The 8D process is one of them.

An underlying assumption for the use of many statistical tools is that your data is normally distributed. But, how do you know? The A-square calculation for the Anderson Darling Normality Test will tell you.

Even a little bit of leftovers each day can add up to something big. That’s the basic principle and motivation behind accessory planning. The whole purpose of this activity is to find ways to use what would otherwise be wasted to generate further value. Overview: What is accessory planning? Most companies engage in accessory planning […]

The design and manufacture of highly complex products and systems requires close co-operation between multiple suppliers and customers. Without well-defined quality plans and methodologies, products will neither get to market on time, or on budget, nor be defect free. 

5S is often thought of as the foundation for continuous improvement. While traditionally considered only applicable to a manufacturing environment, it’s highly relevant for non-manufacturing operations as well. In this article, we will define 5S, discuss its benefits, and consider its importance to an organization. Overview: What is 5S?  There is some debate as to […]

Average incoming quality is a simple, effective and accessible metric that indicates input quality within a process. Accurate assessment of average quality depends on several other factors, including an established framework for evaluation and consistent screening techniques. Overview: What is average incoming quality? In the context of lean manufacturing and business management practices, average incoming […]

In random sampling, this number is the fine line that separates an accepted lot and a rejected one.

When talking about an alias, alias structure or aliasing, you are talking about Design of Experiments (DOE). More specifically, you are referring to the confounding of effects in a fractional factorial experiment. Aliasing occurs when the estimate of a factor effect  is difficult to distinguish because of the impact of other factors in your experiment. […]

While you may be familiar with Lean Six Sigma as a methodology for improving your processes, have you heard of the Business Process Management System (BPMS)? If not, this article will provide lots of information on what it is and how to use it. Business Process Management System (BPMS) Business Process Management System (BPMS) is […]

Asking the 5 Whys is a quick way to get to the root cause of a problem your organization may be dealing with.

In any business arrangement, it is necessary to know who exactly has the power to make decisions. This is true for everything from approving a sale to granting the request for a change in a process be implemented. Just being in a position of power does not make you a great leader. A lot of […]
