I am assuming the  process with Cpk=.19 is stable.  Can other methods (e.g., a
histogram) be shown to the employees to show them they have a stable process
but it's not meeting the spec much of the time?  Who audits conformance to
specification if the customer doesn't care?  Can we use simpler tools at the
onset of process knowledge?
