For the author, all divisions between managers and workers (and other competing groups within an individual business "empire") are artificial distractions in which individuals within the various "tribes" don't realize that their interests and their company's are the same, to defeat other competitive "empires." He provides advice on how to "unite the tribes" in pursuit of this goal through explaining his 10 "pillars of empire:" vision, leadership, organization, mobility, competitiveness, persuasion, strategy, brilliance, morale, and uniting.
