Business Issue A multibillion-dollar software manufacturer needed to drive down the total $191 million annual cost of supplying its workers with continuously updated workstations. Both the software manufacturer and its primary vendor/supplier were in the midst of an aggressive cost cutting initiative that would lead to a new compensation model. The initial, first year targeted […]

Appropriately implemented, Six Sigma clearly produces benefits in terms of better operational efficiency, cost effectiveness and higher process quality. Perhaps less obvious – and until recently less documented – is the impact it can make in clinical areas such as infection control and medication delivery. Clinicians are often receptive to Six Sigma given its familiar scientific and […]

This article provides an example of how an operational department (like a cardiac catheterization lab) can be transformed from a low sigma level to a higher sigma level, and what that would mean to the overall organization. Patient satisfaction, physician satisfaction, reduced overtime, reduced patient wait times, increased revenues and an enhanced quality of life […]

This article illustrates the Six Sigma DMAIC (Define, Measure, Analyze, Improve, Control) process using an organization that develops software packages as an example. The Six Sigma DMAIC approach to process improvement provides a powerful mechanism for improving the software process. Typical benefits will exceed costs within 6 to 12 months from initiation of a Six […]

Whenever I attend a Six Sigma symposium or healthcare conference, the same question comes up: “What’s the difference between Six Sigma and what we’re already doing?” Of course my response is, “Tell me more about what you’re doing so I can better answer that question.” After fielding this question for over a year, I’ve come […]

This article illustrates the Six Sigma DMAIC process using an organization that develops software packages as an example. The Six Sigma DMAIC approach to process improvement provides a powerful mechanism for improving the software process. Typical benefits will exceed costs within 6 to 12 months from initiation of a Six Sigma program for software development, […]

Located in Lafayette, Louisiana, Our Lady of Lourdes Regional Medical Center recently began working with GE Medical Systems to implement Six Sigma as a method for achieving quality and process improvement. Since patient throughput and bed availability are among the organization’s top concerns, the team began by focusing on this issue. Following a process of […]

Finding solutions to staffing issues in the orthopedic unit at Valley Baptist Health System required a dual emphasis on productivity and quality.

Evidence pointing to the applicability of Six Sigma and related best practices within healthcare has been steadily mounting over the past few years. Primarily based on the implementation of the DMAIC process (Define, Measure, Analyze, Improve and Control), we’re seeing an ever-widening array of documented and publicized results… from improving turnaround time for patients to […]

Imagine you are the quality manager for a consumer electronics manufacturer. At the previous staff meeting, the CEO asked the management team for ideas that could help the company become more competitive and increase profits. It is now one month later. During the staff meeting, members of the marketing department present some research that shows […]

We know that everything in business is a process, right? Sales people have a list of companies and contacts that they work in a certain fashion to produce a sale, production receives an order and schedules the manufacturing, the product is built, packaged, shipped and invoiced. When the packing department has a problem with their […]

A Black Belt used Six Sigma to improve a transactional bank deposit process, resulting in yearly savings of $4 million.

Imagine the scenario. Herman and Gary both manage processes for your company. Herman’s process involves a simple matching of supplier invoices to purchase orders. Gary’s process is much more complex. This process involves compliance to government regulations and requires massive amounts of data to be taken, accurately summarized and reported in several different formats to […]

In 2006, the board, administration and staff at Louisiana’s Thibodaux Regional Medical Center (TRMC) decided their operating room (OR) suites represented an opportunity for improvement. Rising demand, costs and competition were all signals that the hospital would need to either invest in expansion or operational efficiency. Taking the less glamorous and more difficult path of […]

Since 2001, Thibodaux Regional Medical Center (TRMC) in Louisiana has applied Six Sigma and change management methods to a range of clinical and operational issues. One project that clearly aligned with the hospital’s strategic plan was an initiative to reduce nosocomial or hospital-acquired pressure ulcers, because this is one of the key performance metrics indicating […]

Efficiency in projects comes from effective risk management. Through an example from a telecom supplier, see how Six Sigma’s DMAIC methodology can be applied in tandem with the six steps of project risk management.

“You don’t know what you don’t know.” That phrase has been taught in Black Belt training for many years, and it continues to be relevant today. When combined with a related phrase, “What you don’t know can hurt you,” these words illustrate a common challenge: Sometimes, the events that hurt us are unknown and unexpected. […]

What is the usual way most people go about solving problems? Most people and organizations consciously or unconsciously use this method, as illustrated in Table 1 below. Table 1: Normal Method of Problem Solving Step Example 1. Understand what is to be improved and set a goal I am too fat. I want to reduce […]

Comparing and contrasting the way different disciplines and tools map to one another can help lead to a better understanding of each of the things being compared. This paper reviews a methodology called IDEALSM, which was developed and evolved by members of the Software Engineering Institute (SEI), and compares it with the Six Sigma DMAIC […]

Orthopedic and neurological spine surgery represents a competitive and profitable business for many healthcare organizations. Expanding this particular service line and ensuring efficiency in the operating room (OR) are among the strategic initiatives at Memorial Hermann Southwest Hospital in Houston, Texas, U.S.A., one of 16 hospitals in the Memorial Hermann system. Surgeons at the hospital […]

Manufacturers and transactional firms share a drive to lower costs, reduce cycle time and offer a diverse product mix as they pursue higher profits and an increased market share in a growing global environment. Consumers (those paying for the end product) want products or services that are cheaper, readily available and of a quality that […]

A large corporation recently conducted a competition to identify the organization’s best Six Sigma projects of the previous year. Out of more than a hundred submissions, only one actually validated its improvements with a comparative experiment (z, t, Chi-sq, etc.). What did the rest do? The same thing they did before Six Sigma. The mean […]

In 2004, a small and relatively young technology company (7,500 employees and an annual revenue of $2 billion) implemented the Public Company Accounting Reform and Investor Protection Act of 2002, or what is usually referred to as the Sarbanes-Oxley Act (SOX). In an effort to be fully compliant the company identified and initiated more than […]
