The 8D problem solving methodology is similar to the DMAIC approach utilized by Six Sigma. Of note, 8D is a shortened form of the original name, ‘8 Disciplines’. The 8D’s are: Identify the problem Use a team approach/form an 8D team Describe the problem Interim containment Define the Read more…
Why is it that when we are in the airport, we don’t wander aimlessly around? It is because of the extensive use of Lean visual controls. Lean practitioners, just like airport designers, know the value of using visual controls. Lean processes should have what airports have: easy to recognize signals Read more…
The definition of consistency (for Lean) is the ability to repeat a process over and over and get the same results every time. Although it is not exclusively a Lean term, consistency is a critical component of Standard Work. Why is it important to continuous improvement? Consistency in processes is Read more…
The 9-square is a prioritization tool in Lean problem solving that helps you organize your improvement ideas. After completing a brainstorming session in which you compile a large number of viable options, you have to decide which ones to implement. To use the 9-square, rank each problem in two categories: Read more…
Precision is the state of having low variation. It is often incorrectly used synonymously with accuracy. Accuracy actually means being centered on the target, but can have a very wide spread. Precision is often much harder to achieve than accuracy. That is because variation can be much trickier to adjust Read more…
The definition of accuracy is essentially having results (data) that is centered on a target value. Statistically speaking, it is how correct the mean value is. It is often confused with “precise.” The layman’s definition of precision is “a measure of how little variation there is in your system”. Lean Read more…
Processes are the bread and butter of continuous improvement. They are the series of linked actions (or steps, tasks, activities, operations, etc.) performed to reach a specific outcome. Processes take randomness and bring it to order. Imagine what would happen if nobody followed a process when driving. No process for Read more…
Where can you find some of the best Lean Six Sigma teams around? The people I’m thinking of don’t spend their day on the shop floor or in an office. They work on the deck of a boat. Surprisingly, a great example of Lean operations is on Discovery Channel’s hit Read more…
I was just winding down watching some TV on a Sunday night, and it struck me that a lot of people are Lean without even realizing it. To be fair, I have a rather broad definition of Lean. I basically use it interchangeably with “continuous improvement“-constantly doing more with less. Read more…
Imagine you are at home, and you hear a funny sound coming from the washing machine, you smell a slight odor of smoke coming from the kitchen, or you see a water mark on the ceiling. Each of these things indicates that something just isn’t right. They are abnormal conditions. Read more…
This may seem obvious, but a brand is the identifier that lets customers know the company producing the product or service they are buying. It distinguishes between the products of different businesses. In many cases, brands are trademarked. To prevent confusion with consumers, other companies are not allowed to use Read more…
Visual management is the concept of creating a more effective workplace by making its current conditions obvious at a glance. But visual management doesn’t stop there. For it to be effective, there must also be a predetermined course of action when a specific (whether normal or abnormal) condition is identified. Read more…
