Start-finish logic
The CIOB Planning Protocol 2021 (CIOB PP21), a technical information sheet published by the Chartered Institute of Building (CIOB) in February 2021, defines start-finish logic as: ‘Logic between activities / milestones which specifies the sequence that the predecessor activity has to start before the successor activity can be finished.’
