Question 6

Step 6: Document Findings, Actions, and Outcomes

Answer 6

Record/document the problem, the troubleshooting steps taken, the solution implemented, and the final outcome. This documentation can be helpful for future troubleshooting and for sharing knowledge with others or be useful in the future when similar problem arises.

Document my troubleshooting steps, changes, updates, theories, and research.
