The Enterprise Model

3

Enterprise vs. Traditional

Project Files are Co-located, Sever Based Files are stored on Hard Drives, Stand- alone Resources may be shared between Projects Resources are available only to the Project Tasks/Activities between Projects may interact Networks must be contained within the Project May be Web-enabled for remote ‘two- way’ access Web access is ‘read-only’

Additional Features:

  • Dashboard
  • Process Refinement
  • Total Project Documentation

Why Enterprise Scheduling?

4

  • 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

“In P3, individual projects are managed separately by

  • ne
  • r

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 “[P3’s]16-bit technology is quickly becoming outdated.”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.”

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.

Advantages:

  • Visualize the project over time
  • Avoid conflicts caused by phasing

Computer/Software Driven:

  • Bentley MicroStation
  • AutoDesk Revit Achitecture
  • Innovaya Visual Simulation 3.0

Summary

19

  • 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
