Schedule Update Procedures:
* Accurate schedule updates rely on entering actual data (start/finish dates, durations) and evaluating impacts of changes.
* "Downstream" logic revisions may be needed but are less critical compared to ensuring accurate historical data and reflecting immediate changes.
PSP Study Guide References:
* Schedule updating emphasizes capturing accurate historical data and estimating remaining durations accurately.
Analysis of Options:
* Option A and B: Key to progress tracking and forecasting.
* Option D: Essential for reflecting impacts of delays and change orders.
* Option C: While important, downstream logic revisions are less immediate compared to other procedures.
Conclusion: The correct answer is C, as downstream logic revisions are less critical in achieving an accurate schedule forecast compared to other updates
