Study Notes

In large computing environments, making changes to applications or operating systems requires following formal change control processes.
Change control process involves planning for the change, estimating risks, having a recovery plan, testing in lab, documenting, and presenting request to change control board.
Troubleshooting process starts with a system or application that may be broken and collects as much information as possible about the problem.
Information gathering includes details about symptoms, user input, environmental changes, and documentation.
Theories on root cause are tested, starting with the simplest explanation and moving on to less common causes.
External documentation and expertise may be required to identify root cause.
Once root cause is identified, a plan of action is created and implemented in production environment with rollback options.
Testing is conducted to confirm the problem is resolved and preventative measures are implemented.
Documentation of the entire process is crucial for future reference.
