Choices:

1) Interview the veteran managers and document their decision rules and practices 2) Delete existing performance data to avoid bias 3) Replace qualitative information with random samples 4) Move all sales records to a public data portal Correct Answer: Interview the veteran managers and document their decision rules and practices Explanation: Institutional or tribal knowledge often exists in employees' experience rather than formal systems.
