Organizations often waste time, money, and resources by fixing symptoms rather than addressing the underlying factors that allowed the problem to occur.</p><p>This poster focuses on the fourth discipline of the 8D methodology: <strong>Identify and Verify Root Causes</strong>. It explains how to move beyond assumptions, investigate systematically, and confirm the actual causes that must be addressed to prevent recurrence.</p><p></p></div><img src="https://ezycourse.b-cdn.net/5664/cmqr0c1r7ayolj7pl6ii0gl01.png" alt="image" containerstyle="position: relative;
