What are the pre-requisites to make JIT work most efficiently? First, We need to understand the method of Heijunka. This method is to balance and maintain of production resources stable; manpower, equipment and standardize the type and quantity of production (daily) and avoid some waste of stock (mainly). The lean way of producing is, to balance the production capacity based on the Takt Time of each process and controls the production quantity through of Kanban, in others words, if the production is not in accordance with Takt Time, the processes are unbalanced and affect the production. Conclusion, We need to produce according to Takt time, this is most important pre-requisites. So, the pre-requisites to make JIT work most efficiently with based on Heijunka are: - Takt Time: We need to know in detail the quantity of necessary (what, how much and what the speed should be produced); - Pulled Production: flow of information (Kanban) - Flow Production: Process in flow (general rule - flow of one part at a time) After that, we need to follow these requisites: - Training of employees to make them multifunctional. - Small lot of production - reduction of setup time. - Avoid the scrap and rework (For example: Pokayoke and Jidoka). And last one, the production need to meet demands (production plan), but to do that we need to follow these points: - Continuously reduce the lead time. Produce in smaller lots. - Need to make question and not agree with stock. - Adjust and control the capacity with mix production. - For the above items, need to use a balanced load.
