Effective project scheduling and time management are critical factors in the success or failure of a particular project. And, increasingly project management professionals are responsible for managing a variety of project schedules and timelines. For that reason, Project Management Institute (PMI) has produced the Practice Standard for Scheduling, a systematic guide describing hallmarks of a sound and effective schedule methodology, as well as providing quantifiable means for assessing the maturity of a schedule model. As a complement to A Guide to the Project Management Body of Knowledge (PMBOK (R) Guide), the primary objective of the Practice Standard for Scheduling is to transform the information in the PMBOK (R) Guide, specifically the project time management section (Chapter 6), into an actionable and objective measurement process for project schedule models and projectschedules.
