AACE International AACE-PSP Exam - Topic 4 Question 42 Discussion

Actual exam question for AACE International's AACE-PSP exam

Question #: 42
Topic #: 4

Each of the following accurately describes total float in a schedule EXCEPT:

AThe amount of time an activity can be delayed without delaying the overall project completion time.

BCan be positive or negative.

CThe amount of time an activity can be delayed without delaying the start or occurrence of any other activity or event in the network.

DComputed for an activity by subtracting its early finish from its late finish, or its early start from its late start.

Show Suggested Answer

Suggested Answer: C

Total float measures the flexibility in an activity's timing within a schedule. It is defined as the amount of time an activity can be delayed without affecting the project's overall completion date or the completion date of any of its successors.

Option A, B, and D accurately describe total float: it is calculated as the difference between early and late start/finish dates, can be positive or negative, and is associated with project completion.

Option C describes free float, not total float, and thus is incorrect.

I’m leaning towards B too. Total float should always be non-negative.

I think D is straightforward. It’s all about early and late finishes.

Option B is the funniest answer. Total float can be positive or negative, just like my mood during exams.

Total float - that's a concept I struggled with a bit in class. I'll need to review my notes and make sure I fully understand it before attempting this.

Total float is definitely the time an activity can be delayed without affecting the project.

Okay, this looks tricky. I'll need to really focus and think through each answer choice systematically. Identifying the one that doesn't accurately describe total float will be the key.

I think I know how to approach this one - I'll need to understand the concept of total float and how it's calculated, then carefully evaluate each of the answer choices.
