Six Sigma as a Methodology


Six Sigma Black Belt Handbook,
By: Thomas Mc Carty, Micheal Bremer,

The Six Sigma methodology builds on the Six Sigma metric. Six Sigma practitioners measure and assess process performance using DPMO and sigma. They apply the rigorous DMAIC (Define, Measure, Analyze, Improve, Control) methodology to analyze processes in order to root out
sources of unacceptable variation, and develop alternatives to eliminate or reduce errors and variation. Once improvements are implemented, controls are put in place to ensure sustained results. Using this DMAIC methodology has netted many organizations significant improvements in product and service quality and profitability over the last several years.
The Six Sigma methodology is not limited to DMAIC. Other problem-solving techniques and methodologies are often used within the DMAIC framework to expand the tool set available to Six Sigma project teams.

These include:
  • Theory of Inventive Problem Solving (TRIZ)
  • Lean
  • Ford 8Ds (Disciplines)
  • 5 Whys
  • Is/Is Not Cause Analysis
Utilizing the sigma metric and marrying this variety of approaches with
the DMAIC methodology, the Six Sigma methodology becomes a powerful
problem-solving and continuous improvement methodology.

hi dear mr taha
six sigma is my interesting fields.
good luck

There are many methodologies used in Six Sigma beside the 5 methods mentioned such as Cost-benefit analysis , SIPOC analysis and etc

Six Sigma is all about reducing the defects to the minimum. Thus while implementing six sigma one should not really be concerned with the size of the organization.

10 Ways to Failure for a New Six Sigma Deployment

10 Ways to Failure for a New Six Sigma Deployment The returns from a well-deployed Six Sigma initiative can be richly rewarding. The results of many business organizations stand in testimony to that. But the opposite also is true. Ten major points are critical to the success or failure of a Six Sigma deployment. Here the points are outlined as the 10 ways that a Six Sigma initiative can fail: 1- Lack of Commitment from the Top 2- Part-time Black Belts 3- Projects Not Linked to Organizational Objectives 4- Focusing on Quantity Instead of Quality 5- No Review Mechanism 6- No Visible Reward and Recognition Mechanism 7- No Infrastructural Support to Teams Working on Projects 8- Copy-and-Paste Deployment 9- Too Much Insistence on Statistics and Tools 10- Expecting Too Much and Too Soon - Ref: www.isixsigma.com

Design for Six Sigma (DFSS) and Crystal Ball Case Study

Background In this case study, we are a compressor manufacturer in the process of developing a new type of compressor. Our project team was charged with developing the design for the compressor using Design for Six Sigma (DFSS) tools and techniques. As we worked through the DMA DV (Define, Measure, Analyze, Design, Verify) process, we used simulation and optimization to provide project justification, lend insight into the critical drivers of quality, and help create a cost effective design th at meets customer requirements. For DFSS, critical benefits of simulation and optimization are the ability to prototype new products or processes without an appreciable investment of time or money, minimal defects, and sales driven through improved customer satisfaction. Define The first step in our Six Sigma process was to estimate the financial impact of this project. We started by developing a simple spreadsheet model (DFSS Case Study Defin e.xls) in Microsoft ® Excel to take into ...

Variation is a serious thing

Many parts have to fit together to make a product, like a cell phone. When engineers design the parts, they account for the fact that all parts will display some amount of variation as they are produced. Variation is the degree to which a part, product, service, or transaction differs from all others in the same class or category. In the case of a phone, each class of parts, like the plastic casting, vary in size, weight, and even color. Just as the phone cases vary, so does the clear plastic display that covers the liquid crystal display. Then you have the many hinges, buttons, antenna, internal component, and so on. All these parts have to snap and fit together well if the phone is to perform its function to your satisfaction. In other words, you can only tolerate a certain amount of variation. A little too much variation and the phone won’t work property. A little more variation and it won’t work at all. And we all know who’s going to end up with the bad phone, right?
