A visual control builds on 5S. It uses organization and standardization to make an abnormal condition stand out. In a Lean environment it does three things: A visual control shows the current condition quickly. A visual control shows what the standard is quickly. A visual control links to an action. Read more…
A pull system (or pull production) is one in which items are only made, transferred, shifted, withdrawn, etc., when there is demand from a downstream customer. This sharply contrasts from a push system in which the downstream actions have no impact on what the upstream process is producing. Pull systems Read more…
Lean often uses the analogy of running water. Making products move quickly and effortlessly is described as flow. Flow is often likened to straightening out a meandering river into a smooth, straight channel. The processes that get those products and services to the customer are known as the value stream. Read more…
Lean makes extensive use of the term flow. As a result, one of the most common teaching analogies Lean practitioners use is that of a meandering river being slowly but surely turned into a deep, straight, fast moving channel. That flow starts at the supplier and finishes at the customer. Read more…
A value stream map (VSM) is a drawing that depicts the flow of material and information along a value stream. A value stream is the linked series of processes that brings a product from raw materials into the hands of the customer, or that provide a service to a customer. Read more…
The current state value stream map provides a 30,000-foot snapshot of how an organization operates. One of the unique aspects of this tool compared to others is that it shows the flow of both materials and information. This tool is extremely useful for a few reasons: It provides eye-opening insight Read more…
TPS is the acronym for the Toyota Production System. TPS is more of a business philosophy than a production system, though. It focuses on manufacturing and logistics but doesn’t neglect the human aspect of production. TPS was founded in large part by Taiichi Ohno. TPS can trace its origins back Read more…
