I have always wondered why library schools teach management courses at all. I cannot imagine a library school that is not located on a campus that has a school of business or public administration. These schools hire specialists in management to teach their courses in management. The other thing about that public adminstration school that is relevant here is that when they require statistics, they send their students to the math department for stat courses. I always advise students to take the best instructors they can for the subjects they need regardless of which school offers the best instructor.
Management is too important to have poor grounding.
What needs inspected a bit is the implied suggestion that management is management. That's substantially true. Send LIS students to some computer science depts and they will learn about computer innards and the wonderfulness of digitalization. But LISers need to learn about the practice of information transfer, and the origin, behavior and use of information. That's our field.
