How Retained Logic, Actual Dates, and Progress Override Deal With Out-of-Sequence Progress


Look at an issue that may arise when you are either preparing or reviewing a schedule update.

In particular, we’re going to look at how your scheduling software may address “out-of-sequence” progress. In construction scheduling, “out-of-sequence” progress occurs when activities begin, progress, and finish earlier than expected (based on the logic and activity durations in the latest schedule). Oracle’s Primavera P6 Project Management (P6) scheduling software provides users with three different options with which to handle out-of-sequence progress. Download this white paper for details on these scheduling options.
