Organization-Wide Planning and Deployment Flashcards
What is six sigma?
Highly disciplined process that focuses on developing and delivering near-perfect products and services consistently
What does world class performance mean in respect to six sigma?
Cpk>1.5
What does sigma mean?
standard deviation of a process about its mean
In a normally distributed process, how many measurements fall within 3 sigma
99.73
In a normally distributed process, how many measurements fall within 4 sigma
99.99932
Normal operations tend to shift how far over time
1.5 sigmas
6 sigma = x ppm
3.4
DMAIC process =
define, measure, analyze, improve, control
Business successes that result from a six sigma initiative include
cost reductions, market share growth, defect reductions, culture changes, productivity improvements, customer relation improvements, product and service improvements, cycle time reductions

Walter Shewhart contribution

Genichi Taguchi contribution

Quality Trilogy is made up of
Quality Planning, Quality Control, Quality Improvement
Quality Planning
used to create the process that will enable one to meet the desired goals
Quality Control
Used to monitor and adjust the process
After Quality Planning and Control, what will reduce chronic losses that are normal for the controlled state?
Only quality improvement activities will reduce the chronic losses and move the process to a better and improved state of control
What is a lean enterprise
it encompasses the entire production system, beginning with the customer. It includes sales outlets, the final assembler, product or process design, and all tiers of the supply chain (including raw materials).
What are lean techniques
In their most basic form, the systematic identification and elimination of waste, the implementation of the concepts of continuous flow, and customer pull.
benefits of lean production systems
lower production costs, fewer personnel, quicker product development, higher quality, higher profitability, and greater system flexibility
five factors driving the lean producer:
cost, quality, delivery, safety, and morale
Henry Ford contribution
father of mass production, founder of Ford, advocated waste reduction, brought affordable transportation to the masses
Shingeo Shingo contribution
Developed the SMED system, assisted in the development of other TPS elements
