Knowledge Leader, Core Traits of a Reliable Schedule

As the primary author of the “Core Traits of a Reliable Schedule,” Dr. Gui endeavors to codify the essential elements of a reliable schedule into a comprehensive protocol. “Core Traits of a Reliable Schedule” contemplates CPM and GPM schedules and further highlights that a comprehensive, credible, well-constructed, and controlled (seen as the four corners of a reliable schedule) schedule captures the notion of a great schedule. This work is a must-read/must-have for any professional aspiring to great schedules.
