Legacy Code Workshop
It was primarily spent getting an area of code into the test harness. Which, is arguably, the least helpful in terms of a workshop.
How to improve:
Getting with someone on site prior to the workshop and getting an area of the code brought into the test harness would be good. Then having them step back a couple of steps so that resolving the problems involved in brining an area of code into the test harness in a controlled fashion would allow for all topics to be covered and more practice in applying the meat of the test harness.
I would definatly be amiable to a multi-day workshop covering this specific topic.
