The effect due to the inter-subsystem coupling on the off-diagonal geometric phase in a composite system is investigated. We analyze the case where the system undergo an adiabatic evolution. Two coupled qubits driven by time-dependent external magnetic fields are presented as an example, the off-diagonal geometric phase as well as the adiabatic condition are examined and discussed.
