1- Collect information. 2- Examine collected information. 3- Eliminate potential causes. 4- Hypothesize underlying cause. 5- Verify hypothesis.
diagnosing a problem
Step 1: Define the problem. Step 2: Hypothesize a probable cause. Step 3: Test Hypothesis. Step 4: Create an action plan. Step 5: Implement action plan. Step 6: Verify problem resolution. Step 7: Create a post mortem report.
troubleshooting methodology steps
1 - Identify the problem.
Gather information.
Duplicate the problem, if possible.
Question users.
Identify symptoms.
Determine if anything has changed.
Approach multiple problems individually.
2 - Establish a theory of probable cause.
Question the obvious.
Consider multiple approaches.
Top-to-bottom/bottom-to-top OSI model
Divide and conquer
3 - Test the theory to determine cause.
Once theory is confirmed, determine next steps to resolve problem.
If theory is not confirmed, re-establish new theory or escalate.
4 - Establish a plan of action to resolve the problem and identify potential effects,
5 - Implement the solution or escalate as necessary,
6 - Verify full system functionality and if applicable implement preventive measures.
7 - Document findings, actions, and outcomes.
