To create a PERT chart, we need to first identify the tasks and their dependencies. Based on the previous tasks provided, let’s assume the following tasks and their durations:

1. Task A: Project Initiation - 2 days
2. Task B: Requirement Gathering - 3 days (dependent on Task A)
3. Task C: Design - 4 days (dependent on Task B)
4. Task D: Development - 5 days (dependent on Task C)
5. Task E: Testing - 3 days (dependent on Task D)
6. Task F: Deployment - 2 days (dependent on Task E)
7. Task G: Project Closure - 1 day (dependent on Task F)

Now, let’s create a PERT chart:

A (2) \ B (3) \ C (4) \ D (5) \ E (3) \ F (2) \ G (1)

In the above PERT chart, the numbers in parentheses represent the durations of each task.

To determine the critical path, we need to identify the longest path through the project. In this case, the critical path is:

A -> B -> C -> D -> E -> F -> G

The total duration of the critical path is 2 + 3 + 4 + 5 + 3 + 2 + 1 = 20 days.

Note: The assumption of 6 people working on the project does not affect the PERT chart or critical path. It only affects the resource allocation and scheduling.
