Question
1. The following AON chart was prepared at the beginning of an important software upgrade project. The duration, in days, follows the letter of each activity. What is the critical path? Which activities should be monitored most closely?
At the end of the first week, it was noted that activity A was completed in 2.5 days, but activity B required 4.5 days. What impact does this have on the project? Are the same activities critical?
2. Refer to Exercise 1. Compute the earliest start and finish times, the latest start and finish times, and the slack times for each activity. Also, calculate the slack for each path.

The concept of critical path states that in the critical path, the longest duration should be considered. hence, the Critical path is the longest past.
Upon adding the time duration of all the possible paths in the diagram, we find that the path ADGJ is the longest with time duration of 14. Hence it is the Critical path.
