Stratification helps teams separate information into meaningful categories—such as shift, product, machine, operator, supplier, or location—making it easier to identify patterns, isolate problem sources, and make better decisions.This printable Stratification poster explains one of the most valuable yet underutilized quality analysis tools in Lean Manufacturing and continuous improvement. It demonstrates how organizing data into logical groups reveals insights that would otherwise remain invisible, allowing teams to focus their improvement efforts where they will have the greatest impact.Whether you're conducting root cause analysis, supporting an A3 project, or analyzing quality data, this poster provides a practical framework for turning large amounts of information into meaningful insight.<img src="https://ezycourse.b-cdn.net/5664/cmrex510s13s91gpg5q5f0qjq.png" alt="image" containerstyle="position: relative;
