PKSC 4300: overview of six sigma
What is Six Sigma?: set of tools based on SPC and TQM to improve quality
What tools are included in six sigma?: - DMAIC (Problem)
DMADV (Design)
SPC/SQC: Statistical process/quality control
SDoC: Statistical Design of Experiment
What is a defect rate?: total quantity defective / total quantity produced
What is run-to-run shift variation?: - the job made one day will probably not have the exact same
average and standard deviation as another job-
increases defect rate by a 1.5 sigma shift
What is +/- 6 sigma represent?: - at +/- 6 sigma, it represents reliable products of material with a 3.4
defects per every 1,000,000
Is +/- 6 sigma achievable?: - Over time it is possible with continuous improvement of the process
It is not economically viable given the cost to reduce variation
-
What does DMAIC stand for?: Define, Measure, Analyze, Improve, Control
