What is the next step after a possible solution is implemented during a troubleshooting process?

After a possible solution is implemented during a troubleshooting process, the next step is to verify its effectiveness by monitoring the system or application to ensure the issue has been resolved. This may involve testing the functionality and checking for any recurrence of the problem. If the solution proves successful, documentation should be updated to reflect the fix; if not, further investigation or alternative solutions may be necessary.
