Enterprise Architectures: Putting Motion, DSI, TOGAF into the cauldron
Iain Mortimer
Architect, Microsoft UK
Enterprise Architects and CIOs are having a really hard time out there.
Business and industry perceptions
The biggest complaints? • IT costs too much. • It takes too long to deliver benefits or doesn't deliver them
at all. • IT is a commodity that fails to deliver differentiation. It
doesn't line up with business strategy.
• Project failures

The choice of EA framework(s) is a major issue
I’m frequently asked
• “is it the right one”
• “will it work”
•Tendency for organisations to see an EA framework as a solution, not as a decision to start a dialogue
Enterprise architects are increasingly bewildered by the number of vying frameworks
Organisations look to EA and Architects for many benefits
And Many Many More…….
Justification becomes the focus of much activity
Many frameworks fail to deliver business benefits or resonate with the organsiation
• Seem to work at the wrong level• Lack of business focus
• Lack of commercialism
• Lots of Technology stuff
• An Architecture is not an IT Strategy
• Ramp up and Lead times too long for initial benefits
• IT people doing Business
Generally summarised as a “communication problem”
For EA to succeed it must refocus itself on to Business problems
• Customer
• Cost
• Shareholder
• Colleague
• Technology
• Process
• Tooling

How? – Review current EA practice in a business perspective and apply it to our organisations
• Understand the organisational problems which lead to EA
• Review how EA frameworks have matured and their weaknesses
• Be able to critically assess the business efficacy of a framework. Practical Application
What were the Organisational problems which lead to EA?
The Genesis of EA was in response to clear business problems
Costs were Paradoxical
• Huge investment in technology but Benefits frequently illusive
• H/W refreshes
• S/w refreshes
Complex technology Stacks
Complexity was daunting
•There is no one single point of discontinuity where EA complexity problems surface
•Employee size
•Number of systems
•Number of technologies
•Diversity of geographies
Many organisations have been paralysed by the complexity of the business & technology and the rate of change in business & technology.
Increase in IT intensity - drove increase in IT estate leading to chaotic and overly complex solutions
Keeping control over IT was increasingly difficult
•They [CxOs] seem to want some overarching framework within which the various aspects of decision making and development are considered.
•MBAs tend to teach very few IT strategy/Architecture models
Business leaders unable to understand in a non technical fashion what IT is in place and how it can be exploited
Trust between Business partners and IT became increasingly fraught
As organisations grew (eg Customer base, product reach and feature set) the complex interplay between business strategy, decision making and IT came increasingly to the fore
“This is the golden bullet”
How have EA frameworks matured?
EA has a long history
• John Zachman presented his seminal work (1987)
• Really a Meta model
• No codification of process
• The interlinks are of more interest
EA has a long history
• Zachman’s model useful diagnostic for EA focus and coverage
EA Concerns focus here
Early activity focussed here
There are numerous models of EA maturity

They tend to measure processes, documentation, lots of hard facts.
They need lots of information

How did EA maturity become so difficult?
• It is amazing for such a top-down strategic discipline that it failed to galvanise Zachman’s thinking. Why?
• Tremendous enthusiasm for EA resulted in the rapid emergence of Dozens of Frameworks• Exploited the IT mind set (iteration, recursion, OODA)
• Exhibiting rapid Darwinism
• Key personnel occupied on the problem for protracted periods
Organisational and cultural maturity models may give us a better clue if an approach will work
Power DistanceEmbodies:
•Stakeholder scope
•Level of concerns
•Hierarchy
•Alignment
•Frustration
•Scope of language
If IT matures like cultures then we should be able to predict what we need for the future

EA seems to mature through four stages - tied closely to the maturity of business relationships
“On Us”
“On You”
“On We”
“For them”

Stage 1 – “On Us”
Context:•IT doing things for IT
Frameworks:•UML•OODA
Results:•Component centric •Construction model •Very Now focussed•Over extension for reuse
Problems:•Micro to macro transformations•Business are not finite state machines

Summary of EA Maturity
L1 -System
An Enterprise Architecture is a description of the goals of an organization, how those goals are realized by business processes, and how those business processes can be better served through technology. R

EA Maturity is about building on previous Architectural activity not reinventing it

Look for frameworks which have a
•Low power distance
•Information focus is at the same scope
•Reach back to previous models
Practical steps
• 1 – Determine organisational (Power) hierarchy
• 2 - Set the tram lines
• 3 – Determine the interests, language at each level• Read the decks they produce
• Try the McKinsey method
• 4 – Think about existing frameworks/projects – how would you draw their focus on your model?
