Chapter 23, Problem 23.5E

Explanation of Solution

When a project is planned, milestones need to be defined. Milestones are associated with a single task or with a group of related tasks. The independent tasks are carried out parallel. A task which is dependent on another task is performed after that particular task is complete.

Bar Chart:

The bar chart that shows the project schedule is given below.

Explanation:

• The time duration taken by the task T1 is 10.
• Task T2 starts after task T1 completes because task T2 depends on task T1 and it will take time duration of 15 and is indicated as a milestone M1.
• Task T3 starts after task T2 completes because task T3 depends on task T1 and T2 and it will take time duration of 10 and is indicated as a milestone M2.
• Task T4 does not have any dependencies. So it will start at the beginning of the project by taking time duration of 20.
• Task T5 also does not have any dependencies. So it will start at the beginning of the project by taking time duration of 10.
• Task T6 starts after task T3 completes because task T6 depends on task T3 and T4 and it will take time duration of 15 and is indicated as a milestone M3.
• Task T7 starts after task T3 completes because task T7 depends on task T3 and it will take time duration of 20 and is indicated as a milestone M4...
