The earliest completion time for a project is the sum of the durations of the critical path activities. The critical path is the longest path through the network of activities with no slack time. The critical path for this project is B-D-F-H-I, with a duration of 12 weeks (3+3+4+0+1+1). Therefore, the earliest completion time for this project is 12 weeks.
