At a high level, Agendashift seems like basic consulting: sell the vision, analyze the gaps, implement the intervention, demonstrate the improvement (and repeat until you're not needed anymore). But what's unusual is that it's the client and not the consultant who identifies both the vision and the interventions. In that regard, it's like Dorthy discovering that the magic to get her home was within her the whole time (Glenda might have told her that before sending a young girl to assassinate her final rival).
What makes Agendashift really interesting for me was the way Mike illustrates the tools he uses to coach an organization through the process, and they are tools we already know well - GROW, Cynefin, Popcorn Flow, etc. In that regard, it's like an invitation to pair coach with Mike and see how he uses the tools to implement a culture of continuous improvement in organizations. That's a journey that's well worth the read, even if the particular tools he uses are all pretty familiar.
