A little lesson on critical path for Allison Tucker and the rest of the Pulte people. (I thought that EVERYBODY in construction knew about, and used, critical path; but, apparently not. This may tell you something about what Pulte people know about construction.)

"It (CPM, or Critical Path Method) was developed in the 1950s by the Dupont Corporation at about the same time that General Dynamics and the US Navy were developing the Program Evaluation and Review Technique (PERT). Today, it is commonly used with all forms of projects, including construction, software development, research projects, product development, engineering, and plant maintenance, among others. Any project with interdependent activities can apply this method of scheduling."
"This process determines which activities are "critical" (i.e., on the longest path) and which have "total float" (i.e., can be delayed without making the project longer). In project management, a critical path is the sequence of project network activities which add up to the longest overall duration. This determines the shortest time possible to complete the project. Any delay of an activity on the critical path directly impacts the planned project completion date (i.e. there is no float on the critical path). A project can have several, parallel, near critical paths. An additional parallel path through the network with the total durations shorter than the critical path is called a sub-critical or non-critical path."
"These results allow managers to prioritize activities for the effective management of project completion, and to shorten the planned critical path of a project by pruning critical path activities, by "fast tracking" (i.e., performing more activities in parallel), and/or by "crashing the critical path" (i.e., shortening the durations of critical path activities by adding resources)."
