www.ThyssenKruppAccessibility.nl2
1Introduction
There is actually only one good method to find the actual cause of a problem, and that is a
systematic manner. Rather than testing or replacing components at random, you adopt a systematic
approach to eliminating possible causes until you have found the real cause.
Systematic fault finding is the systematic reduction of the area of the fault on the basis of:
- the information provided by the user
- your knowledge of the system
- a methodology
- appropriate measurement techniques.
Systematic fault finding offers the following benefits:
- You use a fixed and well-known methodology to carry out the work.
- You work efficiently. You do not duplicate anything.
- You make structured notes of all your findings. This simplifies communications with your
colleagues and Technical Support in the event that you get stuck. “In which step did you get
stuck? How did you get to that step?”
