Boyd Cycle is the project manager of a small project that consists of seven tasks. After careful and extensive planning, Boyd and his project staff agreed on a proposed project schedule and started the project six weeks ago. The original schedule as well as the current status of the project $($at the beginning of the seventh week$)$ is indicated in the following Gantt chart. As indicated, the start of task C was delayed due to the unexpected delay in completing task A; this, in turn, resulted in delaying the start of task C as well as the scheduled start of tasks E and G$.$
