1. Discuss with the customer, patient, user or driver  - do they experience problems that they can describe?

2. Perform preventive maintenance based on age, time since last service, usage time or  driving distance 

3. Perform an inspection according to a standard rutine (predesigned) to discover faults (Inspection of the current state)

4. 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.

​​6.1.2     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​
