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] There are various types of value-stream-mapping software, these include 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 or standalone products specifically designed for value-stream mapping.
Further enhancements often include tools that can analyze the current process and facilitate future state maps (with the provision of "what if" and scenario modelling).
Such tools also make it easier to engage the extended team (management, suppliers, finance, etc.)
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.
