The challenge here is to produce learning experiences that enable someone to move up the curve. In my experience, much of healthcare improvement work is focused on developing data based skills - how to measure change. Some people get to the information stage where they learn to look for patterns, say by using SPC charts. Can they port this knowledge to other projects in a predictable way? Can they make intelligent choices? To what extent do the participants on a QI project become "wise"?
The above curve comes from Designing Knowledge Eco-Systems for Communities of Practice. The web resources are excellent - especially if you are developing CoP's as part of your QI strategy.
