Although Value Stream Mapping is often associated with manufacturing, it is also used in logistics, supply chain, service related industries, healthcare, software development, and product development.
In a build to the standard form Shigeo Shingo suggests that the value adding steps be drawn across the centre of the map and the non-value adding steps be represented in vertical lines at right angles to the value stream. Thus the activities become easily separated into the value stream which is the focus of one type of attention and the 'waste' steps another type. He calls the value stream the process and the non-value streams the operations. The thinking here is that the non-value adding steps are often preparatory or tidying up to the value-adding step and are closely associated with the person or machine/workstation that executes that value adding step. Therefore each vertical line is the 'story' of a person or workstation whilst the horizontal line represents the 'story' of the product being created.
However, software tools are emerging as an alternative. A variety are available either as stand alone products or stencils/add-ons to products such as Microsoft Visio and Corel Corporation iGrafx FlowCharter.
