Using the spreadsheet, what changes were made to schedule version 1 to create schedule version 2?

• A. New activities were added
• B. Durations were shortened
• C. Duration constraints were removed from activities
• D. Critical path was recalculated

Answer: (C)

In a spreadsheet-based schedule, how the timings are determined often comes from constraints you place on activities. If you move from one version to another by removing duration constraints, you’re changing the rules that govern how the timeline is computed. Without those constraints, the model is free to update or re-estimate durations and then recalculate start and finish dates accordingly. This directly produces a new version of the schedule, because the timing now depends on updated estimates rather than fixed limits. Adding new activities or simply shortening durations would change the content or the numbers, but removing constraints specifically alters the governing constraints that drive the schedule calculation, making it the correct change to create the new version. Recalculating the critical path happens as a result of that change, not the change itself.
