When I hear capability model I think competence, competence naturally leads me to motivation. So, capability model, to me, represents a human capital knowledge, ability, and skills framework.
Enterprise, systems, or business architects, view capability models as what a company needs to do to execute strategy.
Any link is a system link and strategy is only as good as the ability to execute. Within the pages of The Capable Company: Building the capabilites that make strategy work, I intend to find capability model methods that identify business and technical details needed for strategic links to execute those capabilities.
