Playground Project Plan Continued

In Lesson 9, you were asked to create a network diagram for a playground project.

To continue from the previous lesson, do the following:

1. Assign a crash duration to tasks that you feel are feasible to crash.

2. Assign total normal costs and total crash costs to each task.

3. Decrease your total project duration by 15%. This may be accomplished using any of the techniques described in the lesson.

4. Write a short narrative describing how you arrived at your new durations in (1) above and your basis of estimate for costs in (2).

The images below are my Lesson 9 work that is mentioned above.

Therefore, the network is relatively insensitive to delays in any individual task. However, delays in the planning phase could potentially delay the start of the entire project, so it is important to ensure that this phase is completed on time. Additionally, delays in the finishing touches phase could delay the opening of the playground to the public
