You are the project manager of the GHQ Project. You are working with your project team to create
the project network diagram. You have created the PND and are identifying the critical path with
your team using your project management information system. All of the activities on the critical
path are showing in red in the software that you are using to evaluate the critical path. What are
schedule activities on the critical path called?

A.
Critical activities

B.
Action items

C.
High alert activities

D.
Red rated activities

Explanation:
Schedule activities on the critical path are called critical activities. Critical activity is a specific
schedule activity on the critical path that takes place within a project schedule. Critical activities
are mainly determined during the execution and deployment of the critical path method. In project
management terms, critical activity refers to being on the major critical path, the most important
path of life of an activity. Critical activity can also be defined as the work elements that must be
carefully monitored, documented, and managed to make the success of an organization, program,
or project. An activity that has a total float equal to zero is believed to be a ‘critical activity’, which
means if an interruption in the finish time of an activity occurs, then the entire project will be
delayed by the same amount of time. A critical activity generally has free float equal to zero.
Answer options D, C, and B are incorrect. These are not valid answers for this question.
