Toyota Production System

Champions pay the price. The list of people who have achieved significant things by working many times harder than most is not long. Toyota is in that list.

It is not any other Production System .It is a unique and revolutionary. It is a break through. Credit goes to Mr. Sakichi Toyoda, Mr. Kichiro Toyoda and Mr. Taichi Ohno. They developed a system suitable for modern times where need is low volumes, high variety. This has become the norm today.

Taylor System was scientific management and the Ford System was for mass assembly line. Taylor was focusing on increasing the efficiencies of the production system. Average Cost per unit was important for Ford while mass-producing the cars. Both these systems are unsuitable for modern times where the high variety with low demand is the order of the day.

What a revolution it started. Now all major automobile companies in the world are having their own Production System, which is nothing but the replica of the Toyota Production System.

The Toyota Production System goal is to produce at low cost with high quality and timely delivery to the customer. Achieving low cost is by completely eliminating excessive inventory and purposeful deployment of the work force.

Waste (“muda” in Japanese) is ‘anything other than the minimum amount of equipment, materials, parts, space, and worker’s time, which are absolutely essential to add value to the product.’

Shoichiro Toyoda

Founder, Toyota

Toyota production system is an effective tool for producing the ultimate goal-Profit. Achieving this by reducing all the costs in the value stream.

TPS also adopts to quickly adjust to change in the market demand without having wasteful slack time.

TPS demands and ensures no process will supply defective goods to subsequent process. Respect for human dignity will be cultivated and ensured.

In TPS 4 things are the most important

  1. 1. Just In Time.
  2. 2. Autonotation.
  3. 3. Flexible work force. (Shojinka in Japanese)
  4. 4. Creative Thinking or working on worker’s suggestions.

To achieve these 4 most important objectives Toyota Production System envisages the implementation the following systems and methods-

  1. 1. 5 S is the foundation for culture of continous improvement.
  2. 2. Kanban System to maintain the Just In Time production. Kanban implementation is to done at all stages of production and storage. When material is used, it is to be immediately replenished by Kanban command.
  3. 3. Production smoothening Method to adapt to demand changes and reduce inventory.
  4. 4. Shortening of the change over time for reducing the product through put time.
  5. 5. Standard Work-Standardization of the operations to attain the line balancing. Standard operations are aimed at using a design based number of workers. Standard Work has 3 elements-
    • Cycle time.
    • Sequence of Operations.
    • Standard Inventory at various stages of operations.
  6. 6. ’Machine Layout’ and ‘Multifunction Workforce ’ for the flexible concept.
  7. 7. Improvement activities by small group and cross functional teams to increase the work morale, bring in Total Employee Involvement.
  8. 8. ‘Visual Control System’ is implemented to achieve the Autonomous concept. In TPS special types of devices are used to detect the defects and automatically stop the line or the workforce is authorized to stop the line when they see a defect.
  9. 9. Build In Quality. It is ‘Functional Management System’ to promote company wide quality control. Quality assurance, as defined in this rule of Toyota ,is to assure that the quality of the product promotes satisfaction, reliability, and economy for the customer. The quality assurance is to assured in all phases of the manufacturing/Services like –
    • Marketing.
    • Product Design.
    • Production Planning and control
    • Purchase.
    • Manufacturing.
    • Quality Assurance and Quality Control. Quality Audit.
    • Sales and services.

Taichi Ohno says: making a factory operate for the company is just like the human body operates for an individual. The automatic nervous system responds even when we are asleep. The human body functions in good health when it is properly cared for, fed and watered , exercised , and treated with respect. The same approach is to be kept in mind while running the company.
