CUSTOMER PROBLEM ANALYSIS |
HINT:
- In troubleshooting, confirm that the problem symptoms have been accurately identified. Preconceptions should be discarded in order to make an accurate judgment. To clearly understand what the problem symptoms are, it is extremely important to ask the customer about the problem and the conditions at the time the malfunction occurred.
- Gather as much information as possible for reference. Past problems that seem unrelated may also help in some cases.
-
The following 5 items are important points for problem analysis:
What
Vehicle model, system name
When
Date, time, occurrence frequency
Where
Road conditions
Under what conditions?
