Value stream mapping software, or VSM software, lets you draw current-state and future-state maps with the standard symbols, then works out the timeline of lead time against value-added time. Options run from free online diagram tools with a VSM shape library to dedicated tools with data boxes, simulation and versioned maps. For the method itself, see the value stream mapping guide.

The basics
Value stream mapping software draws current-state and future-state maps with the standard symbols. It adds the timeline that compares lead time with value-added time.
A value stream map shows the material and information flow for one product family, from supplier to customer. Mike Rother and John Shook set out the method in Learning to See.
Some tools add simulation or process mining. Simulation tests a future state before you change the floor. Process mining builds a map from system event logs.
Most practitioners draw the first map in pencil at the gemba, walking the process from the customer end. The paper-first VSM guide explains why.
Software helps when you need a clean map to share or want the lead time math done for you. It also keeps maps current across many product families.

How the listed tools are priced
Many general diagramming and online whiteboard tools include a value stream mapping shape library, often on a free plan. They are fine for drawing a clean map to share after a gemba walk.
What they usually lack is the arithmetic. You type the timeline and lead time yourself, and nothing updates when a cycle time or inventory count changes. Dedicated VSM tools calculate those from the data boxes as you draw.
At a minimum, look for process boxes with data boxes, inventory triangles, push arrows, supermarkets, kanban signals, manual and electronic information flows, kaizen bursts and the timeline. The value stream mapping symbols guide explains each one.
Data boxes matter most. They should hold cycle time, changeover time, uptime, batch size and the number of operators, so the tool can work out lead time and value-added time for you.
Value stream mapping software draws a map of a process, usually from data gathered at the gemba. It is common in manufacturing, healthcare and office processes.
Value stream management software is a different category for software delivery. It measures flow continuously from the tools engineering teams already use, rather than drawing a map by hand.
