This document discusses process mapping and value stream mapping as tools for visual management and process improvement. It defines a process as a series of steps that take inputs and create outputs, and explains that process mapping visually charts these steps to understand a process. Value stream mapping builds on process mapping by mapping the flow of materials and information needed to bring a product or service to a customer, identifying value-added and non-value added steps to help optimize the process. The document provides guidance on how to conduct a current state and future state value stream map analysis to identify areas for improvement.
