Agenda 1. The Enterprise Scheduling Model Overview 2. Disadvantages of the Traditional Paradigm 3. CPM Scheduling Methods and Procedures 4. Risk Management through Enterprise Scheduling 5. 3-Dimensional Drawings and 4-D Schedules
The Enterprise Model Enterprise vs. Traditional Project Files are Co-located, Sever Files are stored on Hard Drives, Stand- Based alone Resources may be shared between Resources are available only to the Projects Project Tasks/Activities between Projects may Networks must be contained within the interact Project May be Web-enabled for remote ‘two- Web access is ‘read-only’ way’ access Additional Features: •Dashboard •Process Refinement •Total Project Documentation 3
Why Enterprise Scheduling? •Collaboration is now facilitated by co-locating files •Files are now more securely stored •Now PM’s tie-in to each other’s projects •Resources are now managed ‘globally’ •‘Ripple effects’ can now be modeled 4
P6 vs. P3 “In P3, individual projects are managed separately by one or more project managers, each with their own set of codes, resources, calendars, reports, and so on.” “[P3’s]16-bit technology is quickly becoming outdated.” “In addition, a database structure provides better data security.” Source: Migrating from P3 to Primavera v5.0, published by Primavera Systems Inc.

Managing Risk Typical Scheduling Issues: • Resource over allocation • Isolation of projects The enterprise level scheduling system allows us to mange resources globally and simulate interconnectivity between multiple projects.
Resource Allocation 2007 2008 PROJECT A RESOURCE X RESOURCE CONFLICT RESOURCE X PROJECT B
Inter-Project Relationships
3-D, 4-D and BIM Advantages: •Visualize the project over time •Avoid conflicts caused by phasing Computer/Software Driven: •Bentley MicroStation •AutoDesk Revit Achitecture •Innovaya Visual Simulation 3.0 15

Summary •Traditional ‘stand-alone’ schedules inhibit collaboration •Current technology allows enterprise level scheduling •Facilitates program-wide management and simulations •Additional features: ‘dashboards’ and contract management •Scheduling can improve with BIM and 4D 19
