5 Lean Tools and Principles to Integrate into Six Sigma

Integrating Lean into an existing process-improvement framework can result in more high-impact, quick-hit projects. As this experience from one business shows, it's possible to bring in Lean tools without creating ripples in the Six Sigma structure.

A Six Sigma Case Study – Tutorial for IT Call Center – Part 3 of 6

A combination “case study and tutorial” illustrates Six Sigma use in an IT call center. It tracks a DMAIC project from inception through its five phases. The goal is to make a company more competitive and profitable. Third in a series of six parts.

Applying Systems Thinking to the Practice of Six Sigma

To find the most valuable Six Sigma projects – ones with the highest system-level leverage – can require systems thinking and tools like the causal loop diagram, which supplies much more information than the usual cause-and-effect analysis.

Categories of Legitimate Reservation Focuses Fishbone

There is no discipline within fishbone analysis to validate the (logical) connections between one element and another. The tests of can help valid those cause-and-effect relationships.

Causal Loop Diagrams: An Orientation in Software Context

Cause-and-effect diagrams help identify factors (x's) that drive changes in the results variable (Y). But when that tool is not enough, causal loop diagrams can convey causal interconnections that better reflect the way things are.

Causal Loop Diagrams: Little Known Analytical Tool

The causal loop diagram is an analytical tool that is seldom used in Six Sigma but nonetheless is still very valuable. It is a foundational tool used in system dynamics, a method of analysis used to develop an understanding of complex systems.

Cause-and-effect Diagrams and Lean for Service Processes

If too much emphasis is placed upon efficiency in service processes, effectiveness and quality may suffer. For an organization to achieve the best Lean improvement in service processes, efficiency and effectiveness need to be appropriately balanced.

Combining SIPOC with the Cause-and-Effect Diagram

The cause-and-effect diagram, or fishbone, and SIPOC can be used to help find the root causes of defects with speed and accuracy, especially when the improvement project is in a process that the project leader has little to no experience.

Communication and Business Case Key to Revising Process

Through a two-year Six Sigma project, the Department of Defense Acquisition and Technology Programs Task Force (ATP TF) coordinated a revision to a joint weapon system safety review process that provided a 59 percent reduction in cycle time.

Decision-Making with Cause-and-Effect Analysis and DOE

While most companies are using similar techniques informally, cause-and-effect analysis combined with design of experiments can provide real data to help a company decide how and where it can best allocate the funds to improve its business processes.

Determine the Root Cause: 5 Whys

The 5 Whys is a technique used in the Analyze phase of the Six Sigma DMAIC methodology. The 5 Whys is a great Six Sigma tool that doesn't involve a statistical hypothesis and in many cases can be completed without a data collection plan.

Final Solution Via Root Cause Analysis (with a Template)

The most frequent response to a problem is to rush to find an immediate fix. A better approach is to eliminate the root cause so the problem will never recur. Six Sigma's root cause analysis provide an effective way to accomplish this goal.

Harvesting Value in Transactional Processes with Lean Six Sigma

In an era of high competition, with many companies facing a less-than-certain future, the need to increase performance in the eyes of the customer has never been stronger.

Screening Tools Can Speed Up Six Sigma Projects

Although they are not part of the typical DMAIC approach, these tools can decrease the time needed to find solutions.

The Cause and Effect (a.k.a. Fishbone) Diagram

The cause and effect (fishbone) diagram will help you visually display the many potential causes for a problem or effect. Don't be fooled by tool rules; Kerri Simon teaches you to modify the tool for your specific project and subject matter. Free templates are included so you can begin using this tool today.

The Fundamentals of Cause-and-effect (aka Fishbone) Diagrams

A popular means for identifying the causes of a particular problem, or effect, is the aptly named cause-and-effect diagram. As the completed graphic resembles the bones of a fish, it is also commonly referred to as a “fishbone” diagram.

Tree Diagrams for Six Sigma: Plain and Simple?

With the complexity of many of the tools in the Six Sigma kit, it is easy to look at tree diagrams as simple and routine. Experience shows, though, that there are pitfalls and frequently missed benefits. Follow these tips to make the most of four types of tree diagrams.

Using Data Analysis to Identify Six Sigma Sales Projects

Six Sigma's data-driven approach facilitates correlation of factors involved in the sales process and helps isolate specific ways to expand the potential for increasing sales. The end result is a significant source of ideas for improvement projects.

Using Six Sigma to Reduce Pressure Ulcers at a Hospital

A medical center used Six Sigma to reduce nosocomial pressure ulcers by 60 percent, improving patient care and resulting in an annual cost avoidance of $300,000.
