What needs to be clarified
The analysis could distinguish the observed defect, intervention traces and changes documented at different handling stages.
Materials to prepare
- The product, packaging, labels and available accessories in their current condition.
- Sale documents, service requests and records of work performed.
- Before-and-after photographs, the complaint and correspondence about the defect.
What to compare
- Product identity and the sequence of condition changes.
- Connection between recorded traces and particular service work.
- Which possible causes the available materials allow to be considered.
Possible outcome of the analysis
A possible output is a description of current condition, a table of documented changes and an assessment of data needed to test the proposed defect cause.
Limits of the conclusions
Without an initial condition record, the time of damage may be impossible to determine; repair traces do not automatically establish the cause of the defect or a party’s responsibility.
