Too few and your efforts may be fruitless. I think I would have a hell of a time convincing 'manager-types' that quality improvement could be realized in a secretarial pool. In short, it would be nice to hear some first hand accounts of what you have done. Help me with the issues I may encounter before perhaps anything is done. Lastly, it was nice that you interjected humor into the class.
Graduate students are too serious.
The coursepak was also excellent and I liked the format of the lectures. As much as I hate to admit it, I like the frequency of the homework assignments because they immediately reinforce the concepts discussed in lecture. More visuals i.e. would be helpful. Handouts are very helpful. This has been a great course.
