A. Adding the variances of all activities B. Adding the variances of all activities not in the critical path C. Adding the variances of all activities on the critical path D. Choosing the largest variance that occurs from the pool of individual activity variances
A. Adding the variances of all activities B. Adding the variances of all activities not in the critical path C. Adding the variances of all activities on the critical path D. Choosing the largest variance that occurs from the pool of individual activity variances
Explanation / Answer
Option C
The variance is calculated by first identifying the critical path and then adding the variance for each activities in the critical path.
