Value-stream-mapping software
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]
Types of VSM Software
There are various types of value stream mapping software, these includes those that can be used to simply design and construct the maps to software that can carry out calculations and perform detailed analysis. Typically, the software is available as either enhancements to already available programs such as Microsoft Excel, Microsoft Visio – or be standalone products specifically designed for Value stream mapping.
Benefits of using software
Whilst value stream maps are not overtly difficult to construct – utilizing software can help speed up the process and help simplify calculations that help make up a completed map (these calculations include elements such as takt time, inventory, value add time). Further enhancements often include analysis tools that can analyze the current process, and facilitate future state maps with the provision of "what if" and scenario modelling[2]
Drawbacks to using software
Some lean practitioners claim that hand drawn maps are of more benefit describing value stream mapping as a pencil and paper activity [3]. Others state that the most valuable part of a value stream mapping activity are the maps themselves and whilst software can be used for documenting the findings it shouldn’t detract from the process. [4].
