Question 23

True/False

Review LaterAdd Note

A project manager usually staffs the human resources required for a project by hiring outside specialists that only work for the company for the duration of the project.

An activity,A,has two succeeding activities,B and C.Given the following information,determine the latest starting time for activity A. EF B = 15,EF C = 17,LF B = 24,LF C = 27; activity times are A = 4,B = 6,C = 8.

One way that project management differs from management of more traditional operations is the limited time frame of projects.

A hierarchical listing of what must be done during a project is called a project matrix.

Project managers bear the ultimate responsibility for the success or failure of the project.

-What are the estimated standard deviations (in weeks)of the durations for activities A-H?

Companies that are organized as pure project organizations are equivalent to matrix organizations that temporarily group specialists from different departments.

Activity D has an optimistic duration of 3 days,a pessimistic duration of 9 days,and a most likely duration of 4 days.Determine its expected duration and variance.

Given the portion of the network shown above,based on the activity durations shown what is the latest start time of activity 7 if the latest finish of activity 8 is 26,and the latest finish of activity 9 is 23?

The critical path for the network shown is:

If two consecutive activities on the same path each have two days of activity slack,this means that each of them can be delayed by two days without delaying the overall project.

Activity 4 in a network diagram has an optimistic duration estimate of 5 days,a most likely duration estimate of 7 days,and a pessimistic duration estimate of 10 days.The expected duration of Activity 4 is:

Which of the following would probably not involve the use of project management?

Sequential dependencies among project activities are less important than the time required to complete activities.

What is the estimated expected (mean) duration for activity E?

PERT was originally developed for military planning in the 1940's during the Second World War (WWII).

The sum of activity durations of the longest path in a network indicates expected project completion time,and the activities on it are called the critical activities.

The task of identifying risks should involve everyone associated with the project.
