Process Improvement Techniques_Ch 19 Flashcards
Statistically speaking, sigma represents to what extent a ________ ________ ________ ________ and is found by dividing units processed into number of defects and multiplying result by one million.
process varies from perfection
Sigma Examples:
1 sigma = 690K defects/million units
3 sigma = 66.8K defects/million units
6 sigma = 3.4 defects/million units
Philosophically, 6 sigma represents an organization’s desire to achieve basically zero defects, while realistically, most org’s operate at what sigma level?
3 sigma, or ~ 67K defects / million
The five fundamental tools of 6 sigma are:
(DMAIC) Define Measure Analyze Improve Control
Based on Toyota’s production system, Lean is a strategy for achieving the _____ _____ _____ _____.
shortest possible cycle time
T or F
Lean strives to increase value added work by eliminating waste and unnecessary steps, reducing inventory and product development time, and increasing customer responsiveness while providing high quality products as effectively and efficiently as possible.
T
T or F
Cycle time reduction strategies are effective in all aspects of a production process.
F - only in a production process’s critical path.
What Lean technique evaluates the movement of materials, information, and production processes in their current state to identify waste and non-value added activities ripe for improvement.
Value Stream Mapping
The Lean technique that evaluates whether a work place is clean and efficient is known as _____ _____.
Five S
A Lean technique that arranges a work-space so that its status is understood just by looking is known as ______ ______.
Visual Mgmt
A Kaizen Blitz is an intense 3 - 5 day project by people doing the work to rapidly, cross-functionally improve a process. Processes targeted for this strategy are commonly identified through ______ ______ ______.
value stream mapping
To determine production pace relative to demand, _____ _____ is figured by dividing demand time requirements into work time available.
Takt Time
______ is the pull system used to notify a supplier that more product or material is needed downstream for production rather than relying on pure scheduling.
