• Part 1: Don’t Fence Me In• Part 2: So What Worked?• Part 3: Ugh, That could have gone

better…• Part 4: The Future

Part 1: Don’t Fence Me In

The Rule of “Tactical Agility”

2006: Tactical Agility

• Get-er Done• “Flexible and Agile”• Passive Change Control• Heroism at the Interfaces• Architecture in Silos

A Few Good Successes

• Recent Network Redesign• Billiken Info Shield• Campus-wide DHCP• Banner ERP Upgrade• Beginnings of Identity

Management

Part 2: The Birth of EA

“Show me ROI for my investment.” - Ellen Watson,

SLU CIO, 2006

Other Drivers for EA at SLU

• Mitigate Risk Associated with Banner Upgrade and Related Projects

• SAS 112 / SOX IT control levels• Lack of Standards and Documentation• Inconsistent or Undocumented

Architectural Decisions• Lifecycle (Mis)Management• Lack of Coordination across Technical

Boundaries and organizational silos

Section 2: Getting Started at SLU

Our Approach

• Show Quick Results• Build Value through lasting

Processes• Establish Governance• Get “ITS’ House In Order” First• Then Branch Out

The Purpose of Enterprise Architecture

“EA provides a common basis for understanding and communicating how systems are structured to meet strategic objectives.”
