Applying the Jidoka concept to white-collar departments: an examination of the JKK initiative at Toyota Motors

This research paper explores the implementation and theoretical underpinnings of Ji Koutei Kanketsu (JKK), an adaptation of Toyota's renowned jidoka (i.e., autonomation or 'build-in quality') philosophy that was done to apply this approach to Toyota's white-collar departments in Japan. Through a comprehensive examination of the prerequisites, implementation, and effects of JKK, this study aims to elucidate its significance and impact. The research methodology combines interviews and fieldwork conducted at Toyota and its Japanese component suppliers, supplemented by internal documents and published works. The paper underscores the importance of building an organisational culture prominently featuring managerial commitment, visualisation, and open discussion as a prerequisite for successful JKK implementation, which consists of decomposing each individual process into work elements. The study reveals that JKK has numerous potential advantageous effects such as enhanced quality, efficiency, communication, and employee motivation. Furthermore, the study notes the active engagement of Toyota's business partners in JKK activities, suggesting potential avenues for future exploration.
