Unlock with Full AccessThe challenge
A support-ticket archive is being handed to an ML team to train an issue-routing classifier. It contains customer identifiers, free-text conversations and fields that control whether a record may be used for training.
Review the proposed export and handoff against the exercise's explicit rules for access, location, deletion and traceability. Explain how a problem in the handoff could persist into training data or derived copies, and identify the correction needed before training starts.
What you'll practise
Rule-to-data review
Check that the proposed export respects the stated conditions for using each record.
Release traceability
Identify what must remain verifiable through preparation and handoff.
Explain the issue, its consequence and the change you would make.
