Step Description
Step 1 Identify the problem.
  • Question the user and identify user changes to the computer. If applicable, perform backups before making further changes.
  • Inquire about environmental or infrastructure changes that might have occurred.
  • Review system application logs for clues to possible system errors.
Step 2 Establish a theory of probable cause (question the obvious). If necessary, conduct external or internal research based on symptoms.
Step 3 Test the theory to determine the cause.
  • When the theory is confirmed, determine the next steps to resolve the problem.
  • If the theory is not confirmed, re-establish a new theory or escalate the issue.
Step 4 Establish a plan of action to resolve the problem and implement the solution.
  • Refer to the vendor’s instructions for guidance.
Step 5 Verify full system functionality and, if applicable, implement preventive measures.
Step 6 Document the findings, actions, and outcomes.
