DFSS (Design for Six Sigma) is a systematic methodology
utilizing tools, training and measurements to enable us to design
products and processes that meet customer expectations and can
be produced at Six Sigma quality levels.
DMAIC (Define, Measure, Analyze, Improve and Control)
is a process for continued improvement. It is systematic, scientific
and fact based. This closed-loop process eliminates unproductive
steps, often focuses on new measurements, and applies technology
Six Sigma A vision of quality which equates
with only 3.4 defects per million opportunities for each product
or service transaction. Strives for perfection.
Associates are exposed to
various tools and terms related to quality. Below are just a
few of them.
Control Chart Monitors variance in a process
over time and alerts the business to unexpected variance which
may cause defects.
Defect Measurement Accounting for the number or frequency
of defects that cause lapses in product or service quality.
Pareto Diagram Focuses on efforts or the problems
that have the greatest potential for improvement by showing relative
frequency and/or size in a descending bar graph. Based on the
proven Pareto principle: 20% of the sources cause 80% of any
Process Mapping Illustrated description of how
things get done, which enables participants to visualize an entire
process and identify areas of strength and weaknesses. It helps
reduce cycle time and defects while recognizing the value of
Root Cause Analysis Study of original reason for nonconformance
with a process. When the root cause is removed or corrected,
the nonconformance will be eliminated.
Statistical Process Control
of statistical methods to analyze data, study and monitor process
capability and performance.
Tree Diagram Graphically shows any broad goal
broken into different levels of detailed actions. It encourages
team members to expand their thinking when creating solutions.
Black Belt Leaders of team responsible for
measuring, analyzing, improving and controlling key processes
that influence customer satisfaction and/or productivity growth.
Black Belts are full-time positions.
Control The state of stability, normal variation
and predictability. Process of regulating and guiding operations
and processes using quantitative data.
CTQ: Critical to Quality (Critical
Element of a process or practice which has a direct impact on
its perceived quality.
Customer Needs, Expectations
Needs, as defined
by customers, which meet their basic requirements and standards.
Defects Sources of customer irritation. Defects are
costly to both customers and to manufacturers or service providers.
Eliminating defects provides cost benefits.
Green Belt Similar to Black Belt but not a
Master Black Belt First and foremost teachers. They
also review and mentor Black Belts. Selection criteria for Master
Black Belts are quantitative skills and the ability to teach
and mentor. Master Black Belts are full-time positions.
Variance A change in a process or business practice
that may alter its expected outcome.
