01 / The method

Five receipts for eight sheets.

A print operator has three unconfirmed jobs. Should they resend? In one version, the press never received the jobs. In another, it already queued them and the confirmations went missing.

Write the control you would give the operator, choose the evidence you need and decide how to count a successful cut. A worked answer explains the consequences of each route. You can defend a different design.
