Course Introduction

Troubleshooting consists of carefully applying a few simple rules. Quick success cannot be promised, but the data gathering stage is invaluable when the problem must be passed on to another specialist. Formal troubleshooting consists of five steps -

1) listening carefully to a description of the perceived problem;
2) first hand observation of the situation and measurements, when possible;
3) talking with the person who observed the problem;
4) postulating a solution or course of action, based upon knowledge and experience;
5) testing and implementing the course of action.

Alternatively, the troubleshooter can respond to the problem by initially explaining the solution which worked on a similar problem. Both methods require a collection of experience, which will be simulated by this course.
