“This culture (at Toyota) has, in our view, two pillars—the discipline to follow a path of continuous problem solving and self-improvement, and accountability to work standards, fellow team members, company goals, and customer experience. However, we didn’t see these as two separate elements. Somehow they were both interwoven as a single entity that pervaded our daily work. For us, they represented the feeling of the Toyota culture that was atmospheric.” 

Former Toyota employees Tracey and Ernie Richardson describing their ‘DnA’ abbreviation for ‘Discipline and Accountability’ in The Toyota Engagement Equation (McGraw Hill, 2017) p. 5.
