       2. “The shortest total length of a project is determined by the longest path through the network.”  Explain the concept behind this statement.  Why does the longest path determine the shortest project length?

Problem

1. What is the time estimate of the following activity in which  the optimistic estimate is 4 days, pessimistic is 12 days, and most likely is 5 days?  Show your work


2. Consider the following project tasks and their identified best, likely, and worst case estimates of task duration.  Assume the organization you work for computes TE based on the standard formula.  Calculate the TE for each of the following tasks (round to the nearest integer): {SEE THE ATTACHED PICTURE}


3. Construct a network activity diagram based on the following information:

MS Project Exercises

1. Suppose we have a complete activity predecessor table (shown below) and we wish to create a Network diagram highlighting the activity sequence for this project.  Using MS Project, enter the activities and their predecessors and create a complete activity Network diagram for this project.

1. Suppose that we add some duration estimates to each of the activities from exercise 9.1.  A portion of the revised table is shown below.  Recreate the Network diagram for this project and note how MSProject uses nodes to identify activity durations, start and finish dates, and predecessors.  What is the critical path for this network diagram?  How do we know?

Discussion Question (DQ):

1. The advantage of Gantt charts lies in their linkage to the project schedule baseline.  Explain this concept.


2. What are the advantages in the use of Gantt charts over PERT diagrams?  In what ways might PERT diagrams be advantageous?


3. What are some of the advantages in the use of AOA notation as opposed to AON?Under what circumstances does it seem better to apply AON methodology in network development?

MS Project Exercises:

Problem

1. Suppose that we wished to incorporate lag relationships into our activity network.  Consider the table shown below and the lag relationships noted.  Develop an MSProject Gantt chart that demonstrates these lags.
