Steps for Conducting an Ishikawa (Fishbone) Analysis

1. Define the Problem
   Clearly state the problem and write it at the head of the fishbone diagram (e.g., Delaying Work).

2. Draw the Main Categories
   Draw the main branches and label them with major cause categories such as People, Process, Equipment/Tools, Materials, Environment, and Management.

3. Identify Possible Causes
   Brainstorm all possible causes under each category and add them as smaller branches.

4. Find the Root Causes
   Ask "Why?" repeatedly for each cause until the underlying root cause is identified.

5. Prioritize the Causes
   Evaluate the identified causes and determine which ones have the greatest impact on the problem.

6. Develop Corrective Actions
   Plan and implement actions to eliminate or reduce the root causes.

7. Monitor and Review
   Assess whether the corrective actions have resolved the problem and update the analysis if necessary.
