There are a number of tools in COMPASS and I am adding new ones as times goes by. For the moment the two published tools are:
The Mission Canvas helps to understand the long-term mission of the business in terms of the impacts (financial and otherwise) it intends to have as well as discovery why we are on this mission and who we are. This is the starting point for the COMPASS process.
The Customer Discovery Canvas is a tool for exploring, in considerable depth, a customer segment: who these people are, what drives their behaviour, things they desire and how much they desire them, and the outcomes any solution must generate in order to satisfy them and exchange value with them.
