Customer Problem Analysis

CUSTOMER PROBLEM ANALYSIS
In troubleshooting, the problem symptoms must be confirmed accurately and all preconceptions must be cleared away in order to give an accurate judgment. To ascertain just what the problem symptoms are, it is extremely important to ask the customer about the problem and the conditions at the time it occurred.

NOTE: The "Customer Problem Analysis Check Sheet" found under Procedures is a good starting point, but should not be substituted for a personal discussion of the problem with the customer. It may be used to "brief" the service writer on the nature of the problem and should be followed by a description of the problem by the customer "in their own words".


Important Points in the Problem Analysis
The following 5 items are important points in the problem analysis. Past problems which are thought to be unrelated and the repair history, etc. may also help in some cases, so as much information as possible should be gathered and its relationship with the problem symptoms should be correctly ascertained for reference in troubleshooting. A customer problem analysis table is provided in the troubleshooting section for each system.
