When Holly adds resources to the project, as in this instance, she will need to update the activity attributes to reflect the new labor. Activity attributes are an output of the Define Activity process. These attributes refer to the multiple components that frame up an activity. The components for each activity during the early stages of the project are the Activity ID, WBS ID, and Activity name. At the later stages, the activity attributes include Activity codes, Predecessor activity, activity description, logical relationship, successor activity, leads and lags, imposed dates, and constraints and assumptions. Activity attributes are used for schedule development and for ordering, selecting, and sorting the planned schedule activities in a number of ways within reports. In project document updates, activity attributes are updated to include any revised resource requirements and other revision generated by the develop schedule process.

Correct Answer: A

The float for Activity I is three days. The early start for Activity I is Day 17 and the late start for Activity I is Day 20. Therefore, the difference of the early start and the late start reveals the float as three days. It is possible, and acceptable, to use

the difference of the early finish and the late finish to find the float, as the value will be the same amount.

Answer options B, D, and C are incorrect. These are not the valid calculation for the total float.

Correct Answer: A

In other words, activities will not be completed early even if there are no errors or risks. Answer options B, D, and C are incorrect. These are not the valid definitions of Parkinson's Law.
