TPS also emphasizes continuous improvement (Kaizen) and respect for people.
The Role of Teamwork and Employee Involvement
Teamwork and employee involvement are essential components of TPS. Toyota believes that employees are the most valuable asset and that their knowledge and experience should be utilized to improve the manufacturing process. Employees are encouraged to identify problems, suggest solutions, and participate in continuous improvement activities. Teamwork is fostered through the use of small, self-managed teams that are responsible for specific areas of the production process. Employee involvement is key to TPS and Sienna’s quality.
Focus on Quality and Efficiency
TPS places a strong emphasis on quality and efficiency. Toyota is committed to producing vehicles that are defect-free and that meet the highest standards of quality. The company also strives to minimize waste and improve efficiency in all aspects of its operations. TPS principles are applied throughout the Sienna production process, from the sourcing of raw materials to the final inspection of the completed vehicle. This commitment to quality and efficiency helps to ensure that the Sienna is a reliable and affordable choice for families.
