Teaching Tip: Why Quality Inspections Often Fail

We all know that students have trouble staying focused for a long lecture, even with the great job we all try to do. So try to find a short activity that will make a teaching point, break up the class for a few minutes, and get all the students enthused.  Here is something you may want to try in Chapter 6, Managing Quality. It takes about 10 minutes.

In this chapter, we have suggested that building quality into a process and its people is difficult. In the old days, inspection was the main form of quality control. But inspection may not catch all the errors, and it may be expensive. To indicate just how difficult inspections can be, ask your students to turn to the OM in Action box on page 234, called “Inspecting the Boeing 787”.

Ask them to each count the number of E’s (both cap and lower case), including those in the title. This should be a pretty easy inspection job, I think, and I offer a crisp $10 bill to the first student to give me the correct count. That usually gets their attention!

As they each finish, I ask them to shout out their count and I do a tally on the board. There is amazing variation and I only have to shell out the reward in maybe one out of five classes. The answer, by the way, is in the Instructor’s Solutions Manual, as discussion question #18.

If you can share a class exercise of your own, we would be very happy to publish it as a Guest Post.
