Explain when you use the PERT charts and when to use Gnatt charts.

Consider a software project with 5 tasks T1-T5. Duration of the 5 tasks in weeks are 3, 2, 3, 5, 2 respectively. T2 and T4 can start when T1 is complete. T3 can start when T2 is complete. T5 can start when both T3 and T4 are complete.

Draw the PERT chart representation of the project. When is the latest start date of the task T3? What is the slack time of the task T4? Which tasks are the critical path?
