Creating a fishbone diagram involves several steps: 1. Define the Problem: Clearly state the problem you're addressing (e.g., high rates of hospital-acquired infections). 2. Identify Major Categories: These typically include factors like People, Processes, Equipment, Environment, and Materials. 3. Brainstorm Possible Causes: For each category, brainstorm and list potential causes contributing to the problem. 4. Analyze the Diagram: Evaluate the diagram to identify the most likely root causes.
