We are encouraging participants to bring their real work related issues as the topic for a lesson at work. Working on something real often reinforces a lesson much more than some contrived example from a book. Unfortunately, this won't work for our "homework" because of the sensitive nature of what we work on. We still wanted to provide examples that were realistic, practical and left some questions intentionally unasked to encourage people to go out on their own.

When Germany liberalized its telecoms market in the nineties, I worked for one of the American firms that jumped in to compete not just on price, but by offering businesses previously unknown services like itemized bills.

I enhanced the bill with a "Most Frequently Called Numbers" report, and consternation ensued.
