Standardized work
Standardization of work practices allows process steps to be decomposed and optimized into simple easy to follow steps that any operator can easily perform. Standardized practices allow operators and workers to perform tasks the same way every time by using a set standard and clearly defined process which combines and uses different resources effectively such as time, technology, tools on shadow boards and raw materials.
Quality at the source
Quality at the source is a lean manufacturing principle which defines that quality output is not only measured at the end of the production line but at every step of the productive process and being the responsibility of each individual who contributes to the production or on time delivery of a product or service. In a practical sense it would involve each operator checking his or her own work before the part/component or product is sent to the next step in the process. This practice when first implemented within the workforce will be a challenging change to company culture but will highlight the relevance of the product’s or service’s conformance to customer requirements and standards, thus also imparting the importance of quality standards and customer satisfaction within the workforce.
Poka-yoke
Poka yoke is a Japanese term used to describe reliable work methods, tools and processes that eliminates the possibilities of errors being made by production staff that may lead to defects, production downtime and re-work being produced. Poka yoke can also be used to describe a system or tool which allows the conveying of rapid feedback on the performance of a process to the operator of a plant about its performance in time to avoid making errors that lead to defects or production problems.
Seven types of waste in Manufacturing and Business
Waste in any organization or process is referred to the misuse of resources, production not fit for sale or resources that tie up cash and inventory while providing little or no benefit to the organization or its customers. These resources could be better used elsewhere in the organization invested in value creating operations or opportunities. The aim of the lean enterprise should be about identifying and eliminating waste from their systems and operations, and extracting as much outputs as they can from minimal inputs. In lean manufacturing there are seven main classifications of waste, or the so called seven wastes. These are:
-Waiting: time in which people or goods are idle and are not adding value to the finished good or service. This could be due to bottlenecks or production downtime upstream from a sub process.
-Transport: unnecessary movement of materials or goods, this includes work in progress (WIP) from one part of the plant or process to another.
