What type of dependency is being described in the following situation? You are managing the
modernization of a local high school building. You are about to begin the process of completely
removing and remodeling the home economics classroom. The update involves removing all the current
gas cooktops and replacing them with safer electric induction cooktops. To safely remove all the
cooktops, you must first disconnect all the gas lines.
Hard logic
You are managing a project to install a large machine in a manufacturing plant. You cannot start testing
the machine until the machine is fully installed and configured correctly. What dependency does this
describe?
Mandatory
You have been told to use the critical path method using the zero-method rule with a tolerance limit of
+/− 10 percent. Where would you document this?
Schedule baseline
You need to clear a parking lot covered in snow and decide one person should start clearing the snow
before the other person starts putting down rock salt. What relationship does this best describe?
Start to start
You have an expected activity duration of 26 days, optimistic value of 18 days, and pessimistic value of
67 days. Calculate the PERT.
31.5 days
The customer has set a strict project deadline of 85 days for completion. As you review the project
schedule, you notice that one of your paths has a total float of 11 days, and another has a total float of
14 days. Your critical path has a total duration of 55 days, and one of your activities has a free float of 5
days. What is the project float?
Deadline - Critical path
Your customer has approached you and told you that you now need to finish the project two weeks
earlier than anticipated. What does this mean in terms of the critical path?
You have a negative float of two weeks.
You are the manager on a project to build a new wing for the local hospital. The ribbon-cutting
ceremony is set, and many high-profile local dignitaries will be present, so the deadline is set firm and
approaching fast. Unfortunately, the project is behind schedule. You work with your customer to discuss
the best way to bring the project back on track, and the customer decides to crash the schedule. Of the
following, which is the greatest concern to you?
Increased cost
