The process of troubleshooting requires you to decide on a proposed solution to a problem, once this proposed solution has been decided, there is a three stage process you should carry out when implementing the solution so that you can keep track of where you are in the process and how sucessful it has been.
This involves planning, implementing and then testing your proposed solution. Which ensures that you plan, take notes, make notes of existing features, settings and figures etc that were used to that they can be reset if the implmentation did not work as expected.
You should not just blindly attempt the solution without first going through these three stages.
The next three pages will outline each of the three stages.
