Project to Improve a Paper Air Wings System:
Improve:
From the process mapping experience, the placement method was identified as a key input variable. Common sense suggested that careful placement might improve the appearance.
Control:
To verify that the air time was not made worse by the revised SOP, Xbar & R charting based on an additional 24 air wings were constructed and tested.
