STR.13:5.3 - Retrieve the reason, not just the old answer
A practitioner retrieves a five-year-old device/service comparison. It contains a useful explanation of why incident support and data rights mattered. Its numerical estimates and permissions concern the earlier situation.
The practitioner retains the explanation and obtains the current conditions needed for the new choice. An accessible note pointing to the relevant reasoning can solve the memory problem. Rebuilding an archive or repeating the old recommendation is unnecessary.
