Service / Fault tree
In this document I describe how companies focusing on Service / Troubleshooting tend to work. I also think that first line doctors, dentists and repair workshops typically work like this.
-
Discuss with the customer, patient, user or driver - do they experience problems that they can describe?
-
Perform preventive maintenance based on age, time since last service, usage time or driving distance
-
Perform an inspection according to a standard rutine (predesigned) to discover faults (Inspection of the current state)
-
Complimentary tests are performed (e.g patient: temperature, blood pressure and Exray test) (computer aided equipment: faultcode readings) Tests easy to perform and worth the money.
5. Perform an analysis and try to find the problem (Fault tree analysis)
using input from the patient/customer and your inspection.
6. A diagnosis is put in place.
6.1 E.g. patient:
6.1.1 Based on this diagnosis medication and other measures are decided
6.1.2 When having tested the medicine for a couple of weeks, the patient
revisits and the diagnosis and the effect of the medicine are
evaluated.
6.2 Service / Fault tree on Computer steered equipment
6.2.1 Having a computer involved allows you to gather information of
how the product works. Often you can obtain fault codes that can
give a hint of where to start to search for the problem (allows you to
jump into the fault tree
