In the early 1990s, US West was an organization that was leading the charge in telecommunications. At the time, their buildings were being plagued by disruptive false fire alarms. How it was dealt with is a great example of how to apply the Six Sigma quality improvement process, a method applicable to nearly any quality […]

Littelfuse is a manufacturing company that produces electronic products for various industries. The company was facing a problem with its production process, as it was experiencing a high defect rate that was causing delays and increasing costs. Products were experiencing defects and failures, which resulted in customer complaints, rework, and repairs. These quality issues were […]

B & B Ice and Water in Port Arthur, Texas, had been a successful company for many years. Despite their success, the organization was finding a number of problems that they could not seem to solve. By embracing Six Sigma techniques, the organization was able to address these issues, make its company stronger than before, […]

Through the use of Design of Experiments (DOE), a pharmaceutical company was able to extend the shelf life for one of its life saving liquid oncology medicines. Let’s see how this saved the company money, lowered the price of the drug and helped save lives. 

Six Sigma has been defined in three ways: as a metric, a methodology, and a philosophy. Sigma can be defined as the standard deviation of a set of continuous data, so Six Sigma would then be six standard deviations.

In 2010, the finance department of a Fortune 500 company established a quality audit (QA) system for the company’s operations. Toward the end of 2011, the general feeling on the floor was that the QA system was effective and the quality of work in the department was improving. The metrics, however, were not improving. A […]

Manufacturing facilities often are faced with major challenges when it comes to large-scale process improvement. Improving yields at a large manufacturing plant – one that produces millions of pounds of product annually – might require modifications for every step in its process: production equipment, maintenance strategies, operational procedures, process control strategies and analytical support strategies, […]

Considering the performance of the stock market over the past few years combined with current economic conditions, many financial institutions are analyzing their processes for improvements. Unfortunately, the majority of process improvement tools available to Six Sigma practitioners – such as cause-and-effect diagrams, Pareto charts, histograms and scatter plots – have been used for analyzing […]

Any change to a process is only successful in the long run if the stakeholders truly adopt and sustain the change. Process and technology improvements cannot be implemented without a change in the hearts, minds and behaviors of the people involved in the change. True adoption and sustainability requires thoughtful planning and focus, which should […]

1. Use cross-functional teams (CFT) approach to mistake proofing. 2. Selection of process for mistake proofing. During the third phase of advanced product quality planning (APQP), the CFT shall identify the processes, where, due to avoidable human errors, the rating of “occurrence” and/or “detection” have increased thereby increasing the risk priority number (RPN) for the process. Poka-yoke techniques […]

Vilfredo Pareto was an economist who is credited with establishing what is now widely known as the Pareto Principle or 80/20 rule. When he discovered the principle, it established that 80 percent of the land in Italy was owned by 20 percent of the population. Later, he discovered that the pareto principle was valid in other parts […]

PSP and TSP are software development process definitions (some might call them methodologies) that are compatible with a wide range of software development concepts such as spiral development, object oriented development, and various other sets of techniques, each with certain advantages in modeling and describing requirements and designs for software systems. One way of viewing […]

What causes Six Sigma projects to fail to produce desired results, and what would most help to improve Six Sigma project results? This article presents survey results from Six Sigma professionals and presents recommendations.

We need to fundamentally change what’s going on in Software. FAST! Defects, long cycle times, poor estimation, missed targets and project cancellations are stripping away profits and our ability to satisfy and retain customers. It’s occurring in Software Development companies, Embedded Product Software (Firmware), and Business Application Software. And, it’s happening in all industry segments. […]

I’m sure we are all happy to see the new iSixSigma channel dedicated to software. The growing knowledge base at this portal will take shape in the body of articles, discussion forum threads, links, and resources that are contributed. The most important factor in all this is, of course, you, the site participants. While the […]

With the deployment of Six Sigma many organizations ask themselves various questions: What is critical to my customers? What is critical to the bottom line? How do I get a handle on these processes and assure their performance? What should my newly trained Black Belts attack? Without the methodology to pursue the answers, the pressure […]

In the 21st century, new technologies will be developed and improved and will eventually be obsolete for the need of more advanced technologies. In this dynamically changing world, product cycles are expected to last for just a few months. To meet these demanding requirements product developers have to develop products in the shortest amount of […]

Challenges Faced Today Offer Solutions for Tomorrow Six Sigma has come a long way from statistically oriented tools to today’s “not so data driven” tools like Lean and quality function deployment (QFD). The application of Six Sigma across different sectors has made this change from statistical tools to softer tools possible. The methodologies and framework […]

From the inception of iSixSigma Magazine, a regular feature of the publication has been exclusive research on aspects of deploying Six Sigma. The topics benchmarked have ranged from “Black Belt Return on Investment” in the inaugural issue, January/February 2005, to “The Lean Six Sigma Toolset” in November/December 2009. In addition, the magazine reports each year […]

It may be counter-intuitive to consider using Six Sigma tools in an Agile software project. Six Sigma’s genesis was in the manufacturing world where one of its primary goals has been to reduce process variation. On the other hand, Agile software development is built on the premise that complex software projects, unlike manufacturing, cannot be […]

Among the tried and true tools in the Six Sigma kit, cause-and-effect diagrams in the simple form of a tree, a fishbone or a Y-to-x diagram are a big help in identifying factors (x’s) that may drive changes in a results variable of interest (Y). There are times, though, that a flat, two-dimensional hierarchy does […]

Six Sigma DMAIC and DFSS roadmaps provide the guidance needed for using facts and data to understand problems, opportunities and solutions to get results in a wide variety of project settings. For the routine cases, they give practitioners what they need. There are some situations, though, that can benefit from a broader view of Six […]

This article is the first of two on using a systematic approach to implementing a strategic initiative. The second article is “What’s in a Name? Systematic Approach to an Initiative.” For more than 30 years, global competition has driven businesses to seek new and better ways to be competitive in the marketplace. Some companies, in […]

This article is the second of two on using a systematic approach to implementing a strategic initiative. The first article is “What’s in a Name? It’s the Approach, Not the Name.” When a company decides to deploy a strategic initiative, whether the approach is called Six Sigma or something else, it must stay focused on […]
