PDM/CPM Chart and Critical Path

The following network is a compressed representation of the prospectus of a start-up firm that plans to develop a new, bio-electronic computer chip.

Note that four activities, the biological elements, can start immediately.

Find:
(a) The critical path
(b) The earliest time to complete the project
(c) The slack on activities E, F, and H.

WHAT IS THE CRITICAL PATH?

To find the critical path, we need to determine the following quantities for each activity in the
network.

1. Earliest start time (ES): the earliest time an activity can begin without violation of immediate
predecessor requirements
2. Earliest finish time (EF): the earliest time at which an activity can end
3. Latest start time (LS): the latest time an activity can begin without delaying the entire project
4. Latest finish time (LF): the latest time an activity can end without delaying the entire project

We begin at network's origin, START, to compute the earliest start time (ES) and earliest finish
time (EF) for each activity. For the first ...

Solution Summary

This solution is comprised of a detailed explanation to find the critical path, the earliest time to complete the project, and the slack on activities E, F, and H.
