Objectives, goals, states and actions evolve together because learning about the nature of high-level goals is a never-ending process. The distinction between means and ends, which seems obvious and important in simple problem solving, is, as Lindblom explains, not central to practical decision making. The process in which well defined and prioritised objectives are broken down into specific states and actions whose progress can be monitored and measured is not the reality of how people find fulfilment in their lives, create great art, establish great societies or build good businesses.
