The purpose of value-stream mapping is to identify and remove or reduce "waste" in value streams, [2] thereby increasing the efficiency of a given value stream. Waste removal is intended to increase productivity by creating leaner operations which in turn make waste and quality problems easier to identify.
Value-stream-mapping software is a type of software that helps prepare and/or analyze value stream maps. The software typically helps design maps through utilizing a series of symbols representing activity and information/material flow, and as a supplement to manual calculations [ 1 ]
A value stream depicts the stakeholders initiating and involved in the value stream, the stages that create specific value items, and the value proposition derived from the value stream. The value stream is depicted as an end-to-end collection of value-adding activities that create an overall result for a customer, stakeholder, or end-user.
These include: detailed flow-charts, work flow diagrams and value stream maps. Each map is helpful depending on the process questions and theories being considered. In these situations process map implies the use of process flow and the current understanding of the causal structure.
After mapping one or more value streams, engineers and consultants analyze the stream(s) for sources of waste. The analysis may adapt and apply traditional efficiency techniques such as time-and-motion studies as well as more recent lean techniques developed for the Toyota Production System and its derivatives.
Quality filter mapping is part of the value stream mapping [1] toolkit and is used to analyse processes/functions with respect to quality. The results of a quality filter map shows how much waste is being generated within an organisation at each stage of the process. Three types of quality [2] are measured as part of the model:
Angelina Jolie appeared on The Tonight Show Starring Jimmy Fallon to promote her movie Maria, during which the host noticed she wasn't wearing shoes. The actress explained she recently broke her ...
In accounting, value stream costing (VSC) is a technique of costing which entails identifying and calculating costs for all the process steps required for providing value to the customer. It begins with a mapping and tracking all the process steps that provide the value and then quantification of the value created by each step. [1] [2]
