The search for a method to improve productivity is a constant in industries. In this sense, the Just in Time method comes into play, a philosophy that aims to reduce the consumption of resources and eliminate all unnecessary tasks to optimize production processes.
What is the Just in Time method?
The Just in Time method or JIT is a production system that was developed in Japan by the engineer Taiichi Ohno for the Toyota car factory. It is a method based on eliminating everything that is not necessary during the production process.
With this, the aim is to obtain a fluid and flexible production method according to customer demand.
Characteristics of the Just in Time method
Elimination of waste: As we have already mentioned, one of the purposes of JIT is to eliminate everything that is not strictly necessary. This applies from the time of procurement of raw materials to the distribution of finished products. Any expenditure of both material and time should be eliminated.
Pull system: This is the use of pull production systems instead of push production systems. Using this system, production will not start until the customer demands it.
Multi-skilled workers: It supposes that all the workers in the company know how to operate any type of machine, so they will have to be given the necessary training to do so.
Cellular manufacturing: To optimize production, with the JIT system it is necessary to simplify the factory and its organization. This is most often done by arranging the machines in a U-shape so that workers can access them more easily and quickly.
Involvement of the staff: In the JIT philosophy, in addition to the workers being involved in the company, in order to be able to adapt and make any changes quickly, it is advisable to maintain a close relationship with both suppliers and distributors.
Identify the problem: You must be able to identify the problems and solve them as soon as possible. To this end, it is advisable to keep all processes as simple as possible.
The Five Zeros of the JIT method
Zero defects: JIT tries to eliminate any defects that result in increased cost and time. To do this, we must strive to achieve the desired total quality in all areas of the company, starting with the design of the products.
Zero breakdowns: To avoid breakdowns that delay production, productive maintenance systems must be established. In addition, workers must be trained in the conservation and maintenance of machinery so that they can avoid these breakdowns.
Zero stocks: JIT considers stock as a waste of costs. Excess inventory should be avoided.
Zero lead time: The aim is to reduce production cycles in order to reduce waiting times, transit times and set-up times. It is important to have all times planned so as not to cause delays that lead to stock accumulation.
Zero paper: JIT seeks simple management systems. To do this, it is recommended to eliminate bureaucracy and try to carry everything electronically. With our

Advantages of the Just in Time system
The advantages of using this system are as follows:
- Reduce inventory levels at all stages of the production process.
- Reduce inventoryholding costs.
- Reduce costs due to errors in materials or losses in warehouses.
- Minimize losses due to obsolete supplies.
- Increased productivity.
- Flexibility and adaptation to changes.
- Reduction of waiting times.
