InterPlan Systems is currently developing the next generation of the ATC Professional project management software. While we are not at liberty yet to divulge all the new features and enhancements, we did want to highlight the following analysis tool developed by Mr. Stephen Devaux (.PDF link):
The Drag Efficient : The Missing Quantification of Time on the Critical Path
DRAG is a measure of a task’s impact on (or contribution towards) it’s driving successor path. It is a very useful metric for planners / schedulers engaged in critical path analysis tasked with shortening the path duration.
InterPlan Systems has developed a robust implementation of the DRAG metric for our next generation project management software.
