Type the ToolCopy CRC card. Keep the two columns aligned — the layout is the notation.

Answer

Class: ToolCopy (entity) --------------------------------------------- Responsibility Collaborator --------------------------------------------- Know its asset tag - Know its condition grade - Know where it is now Locker Go out on loan Reservation Be inspected on return DamageReport
