The characteristics of TPS, pull-type just-in-time production, require the starting point of end-user demand, emphasize logistics balance, pursue zero inventory, and require the parts processed in the previous process to enter the next process immediately. The production line relies on kanban to transmit information.

The production beat is controlled by manual intervention, and the key point is to ensure the logistics balance in production (each process must ensure the timely supply of the next process). Because it is pull production, the planning and scheduling in production is essentially completed by each production unit, and centralized planning is not adopted in form, but the coordination between production units is extremely important in the operation process.

Extended data:

Toyota's management thought holds that in order to realize timely and stable production, all work must be divided into interrelated processes from the nuances of operation activities, and the operation content, location, operation time and operation performance of each process must be specified.

For example, in the installation of car seats, the installation sequence of screws is the same, the installation time is also stipulated, and even the torque of screws is clearly stipulated.

This accurate management method is not only used for repetitive production activities, but also for all activities of the enterprise, whether it is functional activities or management activities. This kind of management seems simple on the surface, but in fact not all enterprises can do it.

Taking the installation of the front seat of TMM (U.S.A, Inc.) factory as an example, the operator is required to take out four screws from the carton, then install them on the car, tighten them, and then input a code into the computer to show that the whole operation has been completed seamlessly, and then wait for the installation of the next car.

Novices are often taught by experienced old workers. If a novice encounters any difficulties and problems, such as not tightening the screws and forgetting to enter the code, the old workers will immediately help.

The above management phenomenon does not seem very complicated, but it is actually not that simple. If there are a large number of novices on the job site, they often show more job differences than experienced workers, thus making the quality unstable. For example, some operators may install the front screws first, and then install the back screws, and some may be just the opposite;

Some install all the screws before tightening, and some tighten the screws on the side. This difference in work will inevitably lead to low productivity and high cost, and more importantly, the difference in work will inevitably hinder mutual learning and improvement. In order to prevent this from happening, Toyota has formulated elaborate processes and steps, which all employees, whether novice or experienced, must abide by, and any deviation can be found in time.
