A specialized production system built on the idea of acquiring the radical elimination of all types of waste by implementing the most effective methods is what is referred as the Toyota Production System or just as the TPS. The Toyota Production System (TPS) was developed based on two primary concepts:
Jidoka - It can be closely explained as the automation with human maneuvering, as when a problem arises, the machine stops all of a sudden, and thus defective products are not being produced at the first place.
Just-in-Time - The Just-in-Time concept, in which every single process makes only what is required for the subsequent process in a continuous flow.
 
The Concept of JIT
 
Toyota Motor Corporation's vehicle production system is a method of producing products which is also known as a "Lean Production," or "Just-in-Time (JIT) production system," and has exhibited to be recognized and followed globally and reflected for implementation. This production system was established after many years of continuous working on challenges that leads to continuous improvements, with the fundamental notion of manufacturing the automobiles required by customers in the earliest and most effective manner, so as to furnish the automobiles as smoothly as possible.  Founded on the fundamental ideas of Jidoka and Just-in-Time, TPS can effectively and smoothly produce vehicles of top-notch quality, the needed one at a time, that comprehensively complies the customer requirements.

 
TPS and its way of working to cost reduction are the results of aggressive internal strength (gain through years of struggle) and singular advantages for Toyota. The initiatives and developments gained through the implementation of TPS is the benchmark for industries and even the modern day Toyota Corporation.
