reflect organizational learning. There may be
procedural differences in the manner that
different firms collect and report

different. The cumulative number of units
produced is different.
For which of the following should we use an X-bar
chart based on sample means to monitor process
quality? Grades in a freshman "pass/fail" course

pressures in an auto assembly plant

the system, and the service system The service
speed, the queue discipline, and the waiting

services. The service process and service product
can be developed independently. The service
package has the same legal protection available
to manufactured goods. The service package is
the major output of the development process.
