Toyota has built a sustainable competitive advantage through its Toyota Production System which depends on efficient suppliers and a loyal, creative workforce. Building on core competencies and focusing resources in areas of strength while partnering for other needs allows companies to address technical gaps. Companies must own their competitive advantage to continuously improve and stay ahead of competitors who would need a decade to replicate a well-trained workforce. Barriers like brands, technology patents, locations, low costs and distribution systems can protect companies from new competition.
