Utilizing EPC best practices for managing Turnaround Maintenance

It is my experience the folks within the EPC discipline take full advantage of utilizing software's to maximize opportunities, manage expectations, baseline common expectations, manage potential & realized risks and manage performance. I am alluding, specifically to Primavera Project Manager.
Project Managers and Schedulers be it EPC or Facility Turnaround Maintenance essentially, grapple with similar overriding constraints balancing time,resources,quality and cost. From a single Shutdown or Project we often utilize our tools with varying confidence and success. However, where the EPC framework becomes vitally more attractive is when program and portfolio's are developed within an OBS and Portfolio Manager structure. From a Maintenance Shutdown or Turnaround Perspective we can also take advantage of the OBS framework to manage multiple asset outage's throughout the year. This can be a very powerful when tracking and managing multiple asset outages as well as acting as a tool to communicate the big picture with all stakeholder levels.
