Several AACE recommended practices (RP) mention that the scheduler should specifically consider milestones in creating and reviewing the typical construction schedule. These RPs do not detail what should be considered when reviewing milestones. It is not enough for the scheduler to look at them and hope that something 'pops out.'

From baseline schedules to schedule updates, this handy guide gives advanced schedulers more tools to ensure better schedules and better run projects.
