Pretend you are attending a college if you are not and answer the following questions. Putting together college classes for a given term is no mean problem in production scheduling. Like any such scheduling process, glitches may abound. In your time at college, have you encountered in such problems in getting the right courses to you at the right time? If so, what might they have been? (If not, which tutelary deities did you manage to placate?) Why do you think these problems might have occurred? What might have been done to prevent them? Given that your college management and faculty are really pretty bright, why didn't we think of that? The only reason I am looking for help with this question is because I have no idea what some of these words mean or how to answer them.
