Troubleshooting Methodology Quiz

Troubleshooting Methodology

• Identify the problem: Gather information from the user, identify user changes, inquire regarding environmental or infrastructure changes, and perform backups.
• Establish a theory of probable cause: Conduct external or internal research based on symptoms.
• Test the theory: Upon confirming the theory, determine the next steps to resolve the problem; if not confirmed, re-establish a new theory or escalate.
• Establish a plan of action: Refer to vendor’s instructions for guidance.
• Verify full-system functionality and, if applicable, implement preventive measures: Ensure that all components are functioning properly and consider the potential for recurrence.
• Document the findings, actions, and outcomes: Create a detailed record of what occurred and what solutions were implemented.

Gather Information from the User

• Ask the user detailed questions about the problem, including error messages, timestamps, recent system changes and user actions.
• The most recent changes to the system are often the cause of the problem. If something worked previously, it’s likely because of a system change or environmental factor.

Establish and Test a Theory

• Diagnose a problem by identifying the symptoms.
• Consider possible causes and conduct tests to prove or disprove those causes.
• Use research techniques to identify or clarify symptoms and possible causes.
• Utilize web and database search tools, internal documentation, external support resources, and diagnostic tools to gather information.
• Conduct a physical inspection to look for visual signs of damage or malfunction.
• Reproduce the problem by replicating the circumstances that caused the error.
• Question the obvious, as simple issues can be overlooked.

Question the Obvious

• Step through the expected system behavior to identify the point of failure.
• Break down the troubleshooting process into categories like power, hardware, software, network, and user actions.
• Eliminate “non-causes” to isolate the problem to a specific subsystem.
• Use "known good" duplicates to test by substitution.

Establish a New Theory or Escalate

• Establish a new theory if the initial theory is disproven.
• Consider using lengthy procedures to diagnose a cause, but assess the impact on the system.
• Evaluate simpler workarounds.
• Escalate the problem to senior staff, SMEs, suppliers, or support contractors if it is not solvable.
• Document the findings and attempted solutions before escalating.

Implement a Plan of Action

• Determine the next steps to solve the problem.
• Consider repair, replacement, or workarounds.
• Obtain proper authorization for a plan of action.
• Be mindful of potential impacts on other systems.

Implement the Solution

• Implement solutions that have been authorized.
• Consider the most appropriate time and method for network or business disruption.
• Test after each change; if it does not fix the problem, revert it and try something else.
• Document changes to avoid confusion.

Verify and Document

• Test to ensure that the problem has been resolved and the system is functioning properly.
• Complete a problem log to document the problem, its solution, and customer acceptance.
• Implement preventive measures to eliminate factors that could cause the problem to recur.

Document Findings, Actions, and Outcomes

• Create a complete and detailed problem log within a ticket system.
• Use consistent documentation for future troubleshooting.
• Gather troubleshooting steps into a knowledge base or FAQ.
• Collect statistics on problem types and frequency for IT infrastructure analysis.
• Document clearly and concisely for easy understanding.
