A fishbone diagram is a tool to assist in working through problem analyses and visually presenting the product of discussion. Each bone in the diagram represents a key factor thought to contribute to an unsatisfactory outcome. Smaller bones capture details that emerge from conversations about principle factors. Typically, five or six primary factors (“major bones”) may be identified, with multiple contributing factors under each.
Step 1: Identify the unsatisfactory outcome
Step 2: Identify 5-6 major factors thought to contribute to the unsatisfactory outcome
Step 3: Identify contributing causes to major factors
