Six Sigma: Revolutionary business process for improving productivity, reducing costs, and increasing profit. - Six Sigma, The Breakthrough Management Strategy Revolutionizing the World's Top Corporations; Mike Harry, Ph.D., and Richard Schroeder, published by Doubleday.
Guy: A device used to secure something that's likely to shift its position. - Webster's Dictionary
SixSigmaGuy focuses on solving problems (organizational, business, technical, personal, etc.) by applying the Six Sigma methodology of Define, Measure, Analyze, Improve, and Control. Emphasis is applied to analyzing and measuring the current process(es) in use and identifying ways to improve the process(es) to facilitate higher production yield, at reduced cost(s), with better quality. Quicker, Cheaper, Better!!

The biggggggggggggest problem is that we've accepted these huge "rework" and "unplanned" costs as normal for the software industry; but they don't need to be. As Steve McConnell explains, we call ourselves engineers but we don't follow any engineering disciplines in our industry. Other engineering and manufacturing industries would never allow the defect rates that we consider acceptable in software development, "... if cars were like software, they would crash twice a day for no reason, and when you called for service, they’d tell you to reinstall the engine" - MIT Technology Review
What's the Secret to avoiding these costs?
Actually, there is no secret; we actually learned everything we need to know to produce defect-free products in High School. Put simply, we need to do the work we know we are supposed to do in terms of planning, design, and organizing the project and the approach to it's implementation.
Six Sigma puts together what we already know into a set of tools and processes that can be used to analyze the way we/you develop software and identify ways to improve it to produce fewer defects and lower production costs.
