Never-ending improvement is the heart of any continuous improvement effort.  The Deming Cycle, or PDCA, is one of the first formalized approaches to utilize an iterative approach to improving processes, and it still serves as a fundamental tool today for continuous improvement.  This article will describe the stages of the Deming Cycle, the benefits of […]

In today’s competitive business environment, maintaining a high level of quality has become vital to a company’s success. It is imperative that suppliers provide quality parts that meet customer requirements the first time and every time.

Today, we’re looking at two core concepts that deal with the accuracy of your processes. What Is Repeatability? Repeatability is the typical variation that occurs when a person […]

The Robust Design method, also called the Taguchi Method, pioneered by Dr. Genichi Taguchi, greatly improves engineering productivity. By consciously considering the noise factors (environmental variation during the product’s usage, manufacturing variation, and component deterioration) and the cost of failure in the field the Robust Design method helps ensure customer satisfaction. Robust Design focuses on […]

The seven wastes can be summarized with the acronym: DOTWIMP. D: Defect in the output, as identified in the eyes of the customer. O: […]

Increasingly, organizations that use Six Sigma are making an effort to integrate Lean into their existing process-improvement framework. For many, combining Six Sigma’s focus on process quality and Lean’s emphasis on turn-around time results in more high-impact, quick-hit projects. To gain this advantage, however, organizations must face a difficult obstacle: integrating Lean without creating ripples […]

Lean improvement of service processes is somewhat different from Lean improvement of manufacturing processes. Efficiency is usually a measure of speed and cost and Lean improvement in efficiency is achieved by eliminating waste in time or resources. Effectiveness is usually a measure of quality and the overall objectives of the enterprise in that regard. If […]

Because I live in the suburbs, driving downtown to work can be an unnerving experience on the best of days. Even when there are no accidents or stalls, there is a particular stretch of road where the six-lane highway merges into three lanes, creating long traffic jams. Theory of constraints would suggest that there is […]

Developers in an agile setting may want to familiarize themselves with this simple set of Lean tools – quality function development, design structure matrix and visual control board.

In a service organization, the most efficient method for cutting waste is to attack anything and everything that is not done right the first time. This concept, known as first time right, involves making sure that all activities are carried out in the right manner the first time and every time. Examples include a customer […]
