Take the path that is really critical
The Critical Path Method (CPM) highlights those tasks most likely to affect project deadlines. There are, however, several flaws in this approach, including resource availability, fixed dates, elapsed duration tasks, and resource leveling. This article proposes enhancing CPM with a modified critical path called the Resource Critical Path (RCP), which is the true path that drives the project end date. While all resources are critical, usually it is one resource that actually drives the project end date. When many tasks are done in parallel, resources become more critical than tasks; thus, project delays are more often due to resource dependencies than task dependencies. Now that computing power is sufficient to level workloads in a large schedule, enhancing CPM with RCP is a solution to the critical path method's inherent flaws.
