Richard brings up a good point. With a slight bet pf preparation, the instructor can tailor the program to the bank's specific needs.
While at a $43B Florida bank many years ago, we held a 3 day internal compliance conference - including assignments, catered lunches, etc. In addition to compliance (mandatory attendance), as the instructor touched on the various topics (sessions were usually 1-2 hours), representatives from the various business lines and their managers were invited so they could obtain additional knowledge and nuances from the compliance regs. and ask questions from the presenters.
Although we were specialized to different areas (deposits, loans, etc.) we were also backup for each other. The 3 days were intense, but compliance and the lines of business rated the experience as well worth the time.
