Utilizing lessons learned and incorporating them into subsequent waves of an implementation plan creates a closed feedback loop and real dramatic bottom-line benefits if the organization invests the time and executive energy necessary to implement Six Sigma as a business strategy! You can also search articles , case studies , and publications for Six Sigma resources. In three case studies, this concept is demonstrated using real examples.
Save Your Steps Six Sigma Forum Magazine Linde Group, a gases and engineering organization, conducted process makeovers at several North American facilities to improve process efficiency using lean and Six Sigma principles.
Lean Six Sigma Deployment And Maturity Models: A Critical Review Quality Management Journal The study signals an important need for scientific insight in the process of implementing approaches such as LSS, and for a more effective translation of established theory in organizational development to forms practitioners can use. Human Side Of Six Sigma: Positive Feedback Six Sigma Forum Magazine This article explores the idea that for a lean Six Sigma project to be successful, team members and others involved in the process must be vigilant about giving positive feedback when commendable behavior is observed.
George, Sr. Six Sigma projects can bring benefits, including increased organizational efficiency, improved customer satisfaction, reduced costs, increased revenues, and more. The Certified Six Sigma Black Belt is a professional who can explain Six Sigma philosophies and principles, including supporting systems and tools.
A Black Belt should demonstrate team leadership, understand team dynamics and assign team member roles and responsibilities. They have basic knowledge of lean enterprise concepts, are able to identify non-value-added elements and activities and are able to use specific tools.
The Certified Six Sigma Green Belt operates in support of or under the supervision of a Six Sigma Black Belt, analyzes and solves quality problems and is involved in quality improvement projects. A Green Belt is someone with at least three years of work experience who wants to demonstrate his or her knowledge of Six Sigma tools and processes.
The Certified Six Sigma Yellow Belt is aimed at those new to the world of Six Sigma who have a small role, interest, or need to develop foundational knowledge. Yellow belts can be entry level employees who seek to improve their world or executive champions who require an overview of Six Sigma and DMAIC.

The real challenge is to reliably deliver a valuable product or service, while running an efficient and scalable operation at the same time as creating a highly competent and engaged team. And then keep that going as things change! This is something that very few achieve. These organizations committed to and executed on the main principles of process improvement, which — at the time — made it worth it. How did they do it? Large groups of people in a classroom, massive binders with printed slide after slide about the technical aspects of Lean Six Sigma techniques.
Organizations either focused on Lean primarily to reduce waste or Six Sigma decreasing defects and variation. And it was almost always focused on Manufacturing. And frankly, there was an over-emphasis on the count of Lean Six Sigma belts people certified as Green Belts or Black Belts instead of on meaningful results. And when there was a focus on results, many times, it was a narrow and singular focus of Dollars Saved. Not Customer or Employee-focused. So, many times, from a customer or an employee perspective, Lean Six Sigma would have been viewed as worthless.
A histogram groups numbers into ranges and is particularly useful when displaying the shape of a distribution involving a large number of observations. Hypothesis Testing A hypothesis test calculates the probability, p, that an observed difference between two or more data samples can be explained by random chance alone, as opposed to any fundamental difference between the underlying populations that the samples came from. So hypothesis testing answers the question, what is the probability that these data samples actually came from the same underlying population?
Multi-Vari Multi-vari analysis is a technique for viewing multiple sources of process variation. Different sources of variation are categorized into families of related causes and quantified to reveal the largest causes. For example, instead of telling you just that a particular shift is a factor and a machine is a factor, multi-vari analysis provides a breakdown for you to say, for example, that machine B on shift 1 is causing the most variation. NPV and IRR compare cash outflows and cash inflows with a nominal expectation of how the value of money will appreciate over time.
Pareto Charts A bar chart in which each bar represents the relative contribution of each cause or component to the total problem, with bars arranged in descending order of importance. There are 4 steps to creating a PDPC:.
Regression Regression analysis is a statistical process for estimating the relationships between variables. Many techniques for carrying out regression analysis have been developed including linear regression, ordinary least squares regression, polynomial regression, etc.
Run Charts A run chart, also known as a run-sequence plot, is a graph that displays observed data in a time sequence. Often used as the foundation chart for a Control Chart.
Scatter Diagrams A scatter diagram, scatter plot, or scatter graph isused to display values for typically two variables for a set of data. The data is displayed as a collection of points, each having the value of one variable determining the position on the horizontal axis and the value of the other variable determining the position on the vertical axis. It stands for:. Michael L. George, McGraw-Hill Here we list 6 Sigma tools and comment and how they can be applied to the process industry.
Historical Perspective 6 Sigma is a set of tools and techniques introduced by Bill Smith working at Motorola in Applicability to the Process Industry If Lean tools could be described as the common sense waste removal tools of the manufacturing industry then 6 Sigma tools should be described as the technical, variability reduction tools of the manufacturing industry.
There are a couple of weaknesses with generic 6 Sigma initiatives that we see generally and particularly at processing sites; The 6 sigma tools address variability very well but they are usually applied in a very confined and narrow business context. This is because prioritising 6 Sigma activities is predominantly an Industrial Engineering or Operations Research activity. The makers of packaged 6 Sigma systems try to extend the scope of application beyond factory and product variability and into the realm of the broader supply chain.
These attempts often flounder because this would be best achieved by a Lean-6 Sigma-Theory of Constraints-Factory Physics program ……. Affinity Diagram A way of grouping ideas usually stemming from brainstorming into groups based on natural relationships ready for review and analysis.
Methodology Six Sigma. Staff — January 9, Does it work? What Six Sigma Means Experts credit Shewhart with first developing the idea that any part of process that deviates three sigma from the mean requires improvement.
The letters stand for: D efine the problem and the project goals M easure in detail the various aspects of the current process A nalyze data to, among other things, find the root defects in a process I mprove the process C ontrol how the process is done in the future DMADV : The DMADV method is typically used to create new processes and new products or services.
The letters stand for: D efine the project goals M easure critical components of the process and the product capabilities A nalyze the data and develop various designs for the process, eventually picking the best one D esign and test details of the process V erify the design by running simulations and a pilot program, and then handing over the process to the client There are also many management tools used within Six Sigma.
Some examples include the following. Five Whys This is a method that uses questions typically five to get to the root cause of a problem. CTQ Tree The Critical to Quality CTQ Tree diagram breaks down the components of a process that produces the features needed in your product and service if you wish to have satisfied customers.
