You have a malfunction. Or your project ran into problems. Or your plant's production has fallen. There could be one main reason, or several reasons for the negative event. There could be a chain of events which was initiated by a root cause. How do you decipher the complex web of events which culminated in the negative outcome? You need a … [Read more...]
Jidoka is the ability of machines and assembly line workers to detect when a quality non-conformance issue has occurred and immediately stop the production line to make the necessary improvements to the process. Jidoka originated in the Toyota Production System, where it was not just the worker's right to "pull the cord," but their responsibility. Far from leaving … [Read more...]
If there is one enemy of business success, it is this: Wastefulness, inefficiency, and uselessness.

Takt time is a lean manufacturing concept which represents the exact rate at which a plant must produce its product to satisfy demand. It is measured in time per production step (minutes, hours, etc.). Although order levels fluctuate for many products and factories, the underlying demand tends to be constant. Hence, the production rate of the plant should … [Read more...]
Poka Yoke is a component of lean manufacturing which involves error proofing of the production process. Like the square peg that doesn't fit into a round hole, it involves designing processes to eliminate the ability to produce poor quality products. Each task in a production process is inspected for defects. If the defects emerging from a task are particularly … [Read more...]
Kanban is a task scheduling method originally developed by the Toyota Production System in the 1960's to track inventory levels. Although it is being still used in some manufacturing plants, today kanban has obtained greater use in the software industry to manage work in progress. It is one of those simple, yet amazingly effective tools that most people who … [Read more...]
Starting from a point of almost complete ruin after World War II, the Toyota Motor Company rose to become the largest car maker in the world in the mid-2000's. This resulted in many inquiries into the source of their success. Starting in 1988, the engineers and architects of Toyota's success began to open up. As a result, the Toyota Production … [Read more...]
Lean manufacturing transformed the manufacturing world during the 2000's. Invented in Japan, where there are neither natural resources nor excess space for production, manufacturing needed to be lean, mean, and efficient to provide value. In turn, the success of japanese manufacturing resulted in an explosion of interest from around the world. The Toyota … [Read more...]
