A Guide to Value Stream Stream Mapping Symbols

Reading time 5 minutes

This guide provides a quick introduction to the basic standardized symbols for value stream mapping. Originally introduced by the Lean Enterprise Institute in “Learning to See“, a workbook published in 2009, they have since gained a life of their own in organizations seeking to optimize their various processes. These icons are by no means a comprehensive or codified set; rather, they serve as a starting point for further collaboration amongst teams.

For a deeper dive into the topic, check out our blog article 10 Keys to Value Stream Mapping for Software Delivery — it provides a comprehensive explanation of value streams, value stream mapping, and where those concepts fit into the world of software delivery.

To get started using these symbols, head over to the Value Stream Mapping Template for editable print and PowerPoint templates.
