A project has four activities that take 4, 3, 6, and 7 days, respectively. What is the total completion time for the project?

multiple choice

• 3 days, because this is the minimum time
• 7 days, because this is the maximum time
• 20 days, because this is the sum of the times
• It is not possible to determine the total completion time from the given information

Conceptual Question 19-3 Consider a project with two activities that…

Consider a project with two activities that are interdependent. Which of the following statements is ?

multiple choice

• Both activities can be carried out in parallel without coordination.
• Static coordination of the two activities implies that the two activities are carried out in an iterative manner.
• Dynamic coordination of the two activities implies that the two activities are carried out in an iterative manner.

None of these statements is .

Consider two projects that have the same activities and the same dependencies. In the first project, the activity times are expected outcomes. The actual times will vary. In the second project, the activity times are always as expected. Assuming the expected activity times are identical across the two projects, which project will be completed first?

multiple choice

• The first
• The second
