Prior to the beginning work on Activity 6001, the scope is changed by executed change order to increase the activity duration by thirty days and rock fill by 100.000 cubic meters If the project has progressed as scheduled up to the point of the executed change order, what activities would be changed on the next project update?

When a change order increases the duration of Activity 6001, two primary types of activities are affected in the schedule update. First, the data for Activity 6001 itself must be changed (i.e., its duration is increased). Second, if Activity 1000 represents a summary activity for the entire project or a Level of Effort (LOE) activity whose duration is linked to the project's start and finish dates, its duration will also change to reflect the new, longer project completion date caused by the delay to Activity 6001. This is a common scheduling practice for representing overall project management or overhead activities.

A. This option is incomplete as it omits the impact on the overall project summary or LOE activity (1000).
B. The project start milestone (a likely role for an early activity like 1000 or 1001) would not change, as the project has already progressed.
C. This option incorrectly omits Activity 6001, which is the source of the change and must be updated.

stating that changes in scope or duration require modifying the schedule logic and recalculating dates.

Page 66. Defines "Level of Effort (LOE)" as "Activity that is not readily measured by a discrete accomplishment... Its duration is determined by its dependent activities." A change to a dependent activity would change the LOE duration.
