Why is this perspective valuable? Because the Critical Path is the best case scenario, and the valid schedule when considering resources must always be longer than the Critical Path, so the length longer than the Critical Path is the only portion of the total project duration that the resourceleveling or advanced scheduling can effect. There are a few ways to compare these results the simplest is to simply compare overall durations, using the Aurora Advanced Scheduling results as the basis: Primavera P6 resource-leveling is 19.3% longer than Aurora ( ) / Using the P6 resource-leveling as the bases: Aurora Advanced Scheduling is 16.2% shorter than Primavera P6 resource-leveling ( ) / Another valuable perspective is comparing the resource-constrained result with the Critical Path that is the situation assuming unlimited resources. The results of the analyses are a follows: Primavera P6 resource-leveling 67 days, 3 hours = days Primavera P6 leveraging Aurora Advanced Scheduling 56 days, 6 hours, 30 minutes = days The difference is absolute terms is over 10.5 days. The project network consists of over 2,500 activities. REFINERY TURNAROUND LEVERAGING ADVANCED SCHEDULING TECHNOLOGY Stottler Henke and a respected P6 consulting company worked in conjunction to analyze a real-world oil refinery turnaround project via Primavera P6 only (utilizing its resource-leveling capability), and Primavera P6 leveraging Aurora s advanced scheduling technology. In addition, another example from manufacturing will demonstrate that similar results occur for other resource-loaded schedules. This whitepaper will illustrate these benefits via the analysis of a real refinery turnaround project. Aurora is an intelligent advanced scheduling engine that can be utilized with Primavera P6 to generate shorter schedules.

For projects that are time critical/resource intensive, advanced scheduling technology can significantly shorten project duration. So in this Whitepaper, resource leveling will refer to the functionality provided in Primavera P6 and other commercial project management software, and advanced scheduling technology will refer to resource-constrained scheduling that attempts to optimize the utilization of resources to minimize the project duration. Even though Primavera does not purport to providing and optimize schedule, is likely that many users of Primavera P6 are NOT aware that the results from the resource leveling process are not optimal, and could be improved upon significantly. Primavera P6 does not try to optimize the allocation of resources in order to generate the shortest resource leveled schedule. The goal of resource leveling in Primavera P6 is to provide the user with a valid resource loaded schedule that does not have any over allocated resources. Primavera P6 provide a resource leveling capability with graphical support to assist users better understand resource usage and optimize resource utilization by hand. It provides a solution for managing projects of any size, adapts to various levels of complexities within a project, and intelligently scales to meet the needs of various roles, functions, or skill levels in your organization and on your project team. Primavera P6 Enterprise Project Portfolio Management is an integrated project portfolio management (PPM) solution comprising role-specific functionality to satisfy each team member's needs, responsibilities and skills. 1 Benefits of Using Advanced Scheduling Technology With Primavera P6 Versus Resource-Leveling Only INTRODUCTION Primavera P6 Enterprise Project Portfolio Management is a powerful, robust, and easy to use solution for globally prioritizing, planning, managing and executing projects, programs and portfolios.
