Is Delay Analysis Science or Art (Part-2)? Is Delay Analysis Science or Art Part-1 One common delay analysis anachronism is adjusting Remaining Durations in Contemporaneous Schedules. This anachronistic approach occurs when analyses are prepared using contemporaneous schedules, but changing them by either increasing remaining durations of non-impacted activities (usually to argue concurrency) or reducing the remaining durations of impacted activities, usually to reduce delay impacts or remove them from the critical path altogether. If these revised durations were unknown contemporaneously, changing them after the fact often eliminates the contemporaneous aspect of the schedule. Another common delay analysis anachronism occurs when[...]
