Dear Ben,
Six Sigma is a set of qualitative and Quantitative techinques to systematically improve processes by eliminating defects and process variation. It is essentially the byproduct of decades of quality improvement methodologies such as Zero Defects. Like its predecessors, Six Sigma asserts that:
-Process variation is an obstacle to reliably delivering high quality products and services, as defined by the customer,
-Continual focus on reducing process variation is the foundation for business improvement and success,
-All business processes (manufacturing, service, administrative, etc.) can be measured, analyzed, controlled, and improved,
-Effective problem solving can only be achieved by data driven decision making, and
-Achieving and maintaining quality improvement requires an organizational commitment that comes from senior management.
These are the tool how we can do it.....
-Process Mapping
-Statistical Process Control (SPC)
Measurement System Assessment (MSA)
-Design of Experiments (DOE)
-Regression Analysis
-Hypothesis Testing
-Quality Functional Deployment (QFD)
-Cause & Effect Diagram/Matrix
-Failure Mode and Effects Analysis (FMEA)
-Mistake Proofing
-Graphical Analysis (Pareto Charts, Run Charts, Histograms, etc.)
Hope this info helps ur purpose.
