I worked through the Critical Chain session of Eli Goldratt's TOC Insights today. There are 4 of them: project management, operations, finance, and distribution. I've worked through all 4 now, over the last few weeks, and they're really good. If you are interested in learning more about the How-Tos of TOC without going broke, they're a good investment of time and money.
As it happens, I just discovered they're all available on iOS. They're not cheap compared to snappy birds, say, but considering they could change your life they're worth looking at.
