Presentation Outline
- We don’t know how to build big IT Systems.
- Big IT needs a radical transformation.
- The starting point is The Snowman Architecture.
- The Snowman Architecture is a radical improvement.

The State of Large IT
- (Standish) 2009 Chaos report published by the Standish Group
- GAO Report 08-105IT.
- The IT Complexity Crisis by Roger Sessions
“An estimated 85% of government IT projects are late, over budget or both.”- The Pew Center on the States, “Focus on Performance”, 2010
“Projects over $10M have a statistically zero chance of being delivered on time, on budget, and with required functionality.”
“OMB and federal agencies have identified approximately 413 IT projects--totaling at least $25.2 billion in expenditures for fiscal year 2008--as being poorly planned, poorly performing, or both.”
“The world economy is losing over $500 Billion per month to IT failure.”

To Summarize Studies
Projects under $1M are almost always successful.
Projects over $10M are almost never successful.
Projects over $20M typically exceed their budgets by over 220% and cost an additional 400% in lost opportunity costs.

Relationship Between Project Dependency and Complexity

Number of Dependencies

So What Does WorkSmall Sub-Systems Few Dependencies
Roger Sessions [email protected]
Two Major Problems
1. When you split up a system you INCREASE the dependencies.
2. You must split up the system BEFORE YOU KNOW the dependencies.

How To Build A SnowmanThe Head consists of business functions that are synergistically related to each other and nothing else.
The Torso consists of the technical systems that support the head and nothing else.
The Arms implement the dependencies between business capabilities and nothing else.
The Bottom consists of the data needed by the Torso and nothing else.
Business Led: The Head controls everythingSmall: Less than few million $Simple: Autonomous with minimal connection points
MaxSize:FewMillion$

This Scales Without Limit

Getting the Head Right
Understand mathematics of equivalence relationships.
Understand functional dependencies.
Understand how the business contours project to lower layers.
Understand business capabilities.
Understand methodologies for early identification of synergies.
Understand tools to track synergistic relationships/dependencies.
Understand relationship between complexity and synergy.

Making the Transformation
Create a group to own the Snowman Architecture.
Choose a smallish project (~ 10M$).
Apply the principles.
Sell to the Business and IT.
Get Executive Buy-in.
Publicize the result, especially the ROI.
Start a Radical Transformation of IT!

Summary- The Snowman Architecture delivers cheaper systems faster that better need the needs of the business.- The Snowman Architecture is based on three important ideas:
- This is a tremendous value proposition for Enterprise Architecture with high ROI for business.
Business drivenSmall projectsSimple Systems
- These ideas can radically transform IT.
