EASY · CASE FILE
The parcel out of order
Easy · WREN DELIVERY DEPOT
Three depot workers describe successive recorded statuses for separate parcels. The depot’s verified workflow was enforced automatically. A reported sequence may start midway through the workflow, but every consecutive change must be allowed.
Read the case file below, or open the interactive desk to examine records, keep notes and submit your reasoning. These are the case materials, without the solution.
Your assignment
Inspect, test and record the finding. What does the verified record establish?
- The source records are verified and their stated conditions apply to every account.
- Find the account contradicted by a record. A contradiction alone does not establish wrongdoing.

Case records
Read each record on its own terms. A claim made by a person is different from a fact established by an independent record.
