1. How does the WBS differ from the project network? 2. How are WBS and project networks linked? 3. Why bother creating a WBS? Why not go straight to a project network and forget the WES? 4. Why is slack important to the project manager? What is the difference between free slack and total slack? 6. Why are lags used in developing project networks? 7. What is a hammock activity, and when is it used? 8. Here is a partial work breakdown structure for a wedding. Use the method described in the Snapshot from Practice 6.2: The Yellow Sticky Approach to create a network for this project. Note: Do not include summary tasks in the network (i.e., 1.3, Ceremony, is a summary task; 1.2, Marriage license , is not a summary task ). Do not consider who would be doing the task in building the network. For example, do not arrange "hiring a band" to occur after "florist" because the same person is responsible for doing both tasks. Focus only on technical dependencies between tasks. Hint: Start with the last activity (wedding reception), and work your way back to the start of the project. Build the logical sequence of tasks by asking the following question: In order to have or do this, what must be accomplished immediately before this? Once completed, check forward in time by asking this question: Is this task(s) the only thing that is needed immediately before the start of the next task? Draw a project network from the following information. What activity(s) is a burst activity? What activity(s) is a merge activity. Draw a project network from the following information. What activity(s) is a burst activity? What activity(s) is a merge activity Draw a project network from the following information. What activity(s) is a burst activity? What activity(s) is a merge activity? From the following information, develop an AON project network. Complete the forward and backward pass, compute activity slack, and identify the critical path. How many days will the project take? The project information for the custom order project of the Air Control Company is presented here. Draw a project network for this project. Compute the early and late activity times and the slack times . Identify the critical path 8. You have signed a contract to build a garage for the Simpsons. You will receive a $500 bonus for completing the project within 7 working days. The contract also contains a penalty clause in which you will lose $100 for each day the project takes longer than 7 working days
