The 6-point fault finding technique is a method for finding and fixing mechanical operating malfunctions. These steps include collecting evidence, analyzing evidence, locating faults, determining and removing causes, rectifying faults and running a systems check. There are certain conditions and actions that exist in order to execute these six steps. One of these conditions is that safety comes first, and these steps should not be taken unless it is safe.
In the course of collecting evidence, the investigator has to use the senses of sight, smell, touch and hearing to know what is wrong with an operating system. Once the collection is complete, an analysis to consider the validity of the information collection begins. After analysis, the fault in the system is located with the aid of evidence analysis. Determining or removing the cause of a problem is the next step to follow the location of a system fault.
Sometimes removing the cause of a system failure is not enough, and the fault must then be rectified. This usually means fixing the cause of the fault or implementing some kind of maintenance. The last step in the process is to check the system and make sure it can return to operation.
