Just-in-time (JIT) is a production model in which items are created to meet demand, not created in surplus or in advance of need. The purpose of JIT production is to avoid the waste associated with overproduction, waiting and excess inventory, three of the seven waste categories defined in the Toyota Production System (known in North America as the lean production model).
JIT was firstly developed within Toyota manufacturing plants by Taiichi Ohno, during the beginning of the 70s. The oil embargo probably triggered his theory, the program was intended to avoid wastes, reduce inventories and increase production efficiency in order to maintain Toyota’s competitive edge. Besides he believed that customers should be satisfied with maximum quality in the shortest time. Read more…
5S represents 5 disciplines for maintaining a visual workplace (visual controls and information systems).
These are foundational to Kaizen (continuous improvement) and a manufacturing strategy based “Lean Manufacturing” (waste removing) concepts.
5S is one of the activities that will help ensure our company’s survival.
- Sort-All unneeded tools, parts and supplies are removed from the area
- Set in Order-A place for everything and everything is in its place
- Shine-The area is cleaned as the work is performed Read more…
What is Kanban?
Kanban is a scheduling system for lean and just-in-time (JIT) production. Kanban is a system to control the logistical chain from a production point of view, and is not an inventory control system. Kanban was developed by Taiichi Ohno, at Toyota, to find a system to improve and maintain a high level of production. Kanban is one method through which JIT is achieved. Read more…

Kaizen is a Japanese term that means continuous improvement. Kaizen events are used to make continual improvements throughout a plant at the process or system level. Process improvements are more detailed and take place on the shop floor by the people who are involved in the specific process at hand. The Kaizen event is used to reduce the waste and non-value added steps in order to minimize the time needed to flow through the processes. The system improvements are generally broader in approach and focus on improving the flow through the entire value stream. Normally Kaizen events are done in less than a week, another term Kaizen Blitz is used which means small improvements are made in a short period of time. Read more…
