Senge describes extensively the role of what it refers to as "mental models," which he says are integral in order to "focus on the openness needed to unearth shortcomings" in perceptions. The book also focuses on "team learning" with the goal of developing "the skills of groups of people to look for the larger picture beyond individual perspectives." In addition to these principles, the author stresses the importance of "personal mastery" to foster "the personal motivation to continually learn how [...] actions affect [the] world."[1]
