Just in time or JIT as it is known, is a system which adopts the idea of improving output without having a large number of inventory at any stage of the supply chain or production process. It aims to produce and deliver on time and in full all customer orders only after these orders are placed on demand by the customer instead of producing/purchasing parts and finish goods to stock. It is an essential component of a lean or lean manufacturing enterprise.
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.
In order to write standard operating procedures you need to understand the task at hand and have at least one operator or technical person who can describe the procedure step by step. If the task is how to operate a certain piece of machinery, then the writing of the procedure must be done with input from the manufacturer. Also remember for simpler procedures or tasks it may be more convenient to write a One point lesson
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.
