Q

The major disadvantage of using a bar chart on large projects is that bar charts:
Cannot identify critical paths
Do not show dependencies between activities
Cannot identify milestones
Cannot show slack

Q

Negative slack is the result of:
The forward pass going beyond the customer’s end date and the backward pass is measured from the customer’s end date
Non-critical-path activity using up all of their slack
The critical path can be completed before the customer’s desired end date
All of the above

A

The forward pass going beyond the customer’s end date and the backward pass is measured from the customer’s end date
