improvement will just be one more variation that is occasionally used and mostly ignored. One must standardize, and thus stabilize the process, before continuous improvements can be made. Toyota’s enabling systems are simply the best practice methods, designed and improved upon with the participation of the work force. The standards actually help people control their own work. Without standardization, you cannot implement effective, long lasting process improvement This essential point of lean manufacturing is often missed. 2. Jidako Concept Jidoka is quality must be built in during the manufacturing process. This will use If equipment malfunction or a defective part is discovered, the affected machine automatically stops, and operators cease production and correct the problem.For the Just-in-Time system to function, all of the parts that are made and supplied must meet predetermined quality standards. This is achieved through jidoka. Jidoka means that a machine safely stops when the normal processing is completed. It also means that, should a quality / equipment problem arise, the

machine detects the problem on its own and stops, preventing defective products from being produced. As a result, only products satisfying quality standards will be passed on to the following processes on the production line. Since a machine automatically stops when processing is completed or when a problem arises and is communicated via the "andon" (problem display board), operators can confidently continue performing work at another machine, as well as easily identify the problem's cause to prevent its recurrence. This means that each operator can be in charge of many machines, resulting in higher productivity, while continuous improvements lead to greater processing capacity. 3. Just-in-Time Concept Just-In-Time (JIT) , Toyota making only "what is needed, when it is needed, and in the amount needed”. It has high possibility to producing quality products efficiently through the complete elimination of waste, inconsistencies, and unreasonable requirements on the production line.

In order to Toyota deliver a vehicle ordered by a customer as quickly as possible, the vehicle is efficiently built within the shortest possible period of time by adhering to the following: 1. When a vehicle order is received, a production instruction must be issued to the beginning of the vehicle production line as soon as possible. 2. The assembly line must be stocked with required number of all needed parts so that any type of ordered vehicle can be assembled. 3. The assembly line must replace the parts used by retrieving the same number of parts from the parts-producing process (the preceding process). 4. The preceding process must be stocked with small numbers of all types of parts and produce only the numbers of parts that were retrieved by an operator from the next process.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
