d) Develop processes that are capable of producing such products
f) Transfer these plans to the operating forces
e) Establish quality controls.
2) Quality Control
(1)Evaluate actual operating performance
(2)Compare actual performance to goal
(3) Act on Difference
Statistical Process Control (SPC)•Histograms
Control charts
Scatter diagrams
Flow Charts
Cause and Effect , Fishbone, Ishikawa Diagram
Check Sheets
