Question: A painting process has as CTQ the lap coating thickness.

We want to reduce the cost by decreasing the application thickness of the paint..

To know that it influences the thickness of the application, we perform a DOE

Considering the following factors and their respective levels:

· Temperature (low / high)

· Time (short / long)

· Viscosity (low / high)

After executing the DOE we arrive at the following graphs:

1. Which factor has less influence on the dressing thickness?
2. To reduce the thickness, should we increase or decrease the temperature?
3. Which factors almost do not interact?
4. What combination of factors provides the smallest thickness?
