Clinical Start-up PERT Estimate

Clinical study start-up three-point PERT

This three-point PERT chart estimates clinical study start-up while exposing uncertainty in regulatory review and site activation. A draft protocol begins ethics review and site selection. Selected sites are contracted, then training waits for both the ethics decision and signed site contracts. Enrollment opens only after training. Optimistic, likely and pessimistic durations give the team a way to plan around review timing and contract variability without treating them as fixed. Extend the network with budget approval, investigator meetings, data-system validation or drug supply release when those steps affect study activation.
