Six Sigma and Beyond: Statistical Process Control, Volume IV

Description : It is very important to redo Phase III after the supplier has delivered and set up the machine in your plant. This will give you a chance to make sure that the machine is set up the same as at the supplier's shop and that it is set up correctly.

Objectives:

• Confirm correct machine setup.

• Reconfirm Phase III conclusions with supplier still in the plant.

Final-step participants include the

• Machine acceptance team

• Supplier of the machine

• Production operator of the machine

• Production engineers

Repeat Phase III study: If Phase III results are not replicated (i.e., C _pk >1.33), have supplier find out why the machine is not set up correctly.
