Lean is an operating philosophy that originally derived from the Toyota Production System. It focuses on shortening the time that elapses between a customer‘s order and the shipment of the product or the provision of the service that fills the order. Lean accomplishes this by eliminating waste from processes, with waste being defined as anything that is not necessary to produce the product or service. Lean helps organizations reduce both costs and cycle time, resulting in a more agile and market-responsive company.
Tools and Techniques
The tools and techniques used during the implementation of lean are referred to as the lean
?building blocks.? Although these tools vary somewhat from consultant to consultant and from company to company, the most common ones can be described as follows.
1.Five S
The Five S technique is named after five words that begin with the letter ?S? in Japanese. It aims to bring orderliness, tidiness, and cleanliness to operations -- along with the discipline needed to keep processes orderly and standardized. See Pojasek, R.B (1999, Autumn). Quality Toolbox. Five S‘s: A Tool that Prepares an Organization for Change. Environmental Quality Management, 9(1), 97-103.
2.Visual Controls
With visual controls, all tooling, parts, and other production activities are kept clearly in view to help every-one involved understand the status of the process at a glance. Visual controls are usually linked to Five S.
3.Poka-Yoke
Poka-yoke literally means ?mistake proofing.? By using poka-yoke, process designs can be modified to make it nearly impossible for mistakes, spills, leaks, and other process upsets to occur. See Pojasek, R.B. (1999, winter). Quality Toolbox. Poka-Yoke and Zero Waste.
Environmental Quality Management, 9(2), 91-97.
4.Cellular Design
Cellular design refers to a technique in which facility layout is designed according to optimum operational sequences. Raw materials, parts, information, tooling, and work standards are stored where they are needed and used. The design model centers around one-piece flow, which is considered to be the best batch size. If this is not appropriate, the batch size is reduced.
5.Quick Changeover
The ability to change tooling and fixtures rapidly allows for multiple products in smaller batches to be run on the same equipment.
6.Pull Scheduling
Under the pull scheduling system, the internal supplier does not produce until an internal or external customer signals a need for the part or service using a kanbal system.
This practice contributes to just in time production and creates what the practitioners refer to as flow. At all times, standardized work or prescribed methods are used. !Kaizen Kaizen is a staged event where many minor adjustments are made in a particular part of a process. This approach allows for continuous improvement.
