DnB NOR’s Expectations for Enterprise Architecture
 See the various IT initiatives in context
 Ability to translate business strategies in into optimal IT solutions
 Help deal with frequently changing customer and business requirements
 Expectation of faster completion of analysis since individual projects can utilize
already-available data
 Commitment to this effort:
o Process governed and owned by the chief architect
o Involvement all the way from business decision-makers, via business architects, to
solution architects and developers
o Team: project manager, subject matter experts, enterprise architects, consultants
o Dedicated Enterprise Architecture Tools

TOGAF in the DnB NOR organization
• Enterprise architecture
• Long term perspective; 3-10 years
• Defines constraints, principles and goals for the
blueprint groups
EA
• Portfolio different business areas with
0-3 years perspective
• TOGAFs segment architecture
• Defines required projects and their
scope
• Secure that projects deliver in
accordance to target blueprints
Portfolio
Blueprint Group
• Deliver in accordance to
specified scope and
premises
• Projects are followed up
by blueprint group with
respect to defined
constraints, goals etc.

Our message to the solution architects
 EA is not about each project “looking at its neighbors”
 It is not about coordinating project initiatives and governing
them at group level
 It is a holistic, top-down approach to implement the business
strategy

DnB NOR’s Approach to Metamodeling
1. Start with usage scenarios – which questions do we need to answer in our
Enterprise Architecture work?
2. Analyze which common information elements contribute to answering the usage
scenarios
3. Seek to find the proper elements in the TOGAF 9 content metamodel or the built-
in elements in the tool (Rational System Architect)
4. If not found – create a new element on basis of existing knowledge/resources
5. Specify the definition or adapt the default definition to our own organization
6. Define the associations between the elements

Advantages of having an explicit metamodel
 Greatly aids understanding
 Greatly aids communication
 Forms the basis for reports
 Forms the basis for constraints

23. The Premier Event for Software and Systems Innovation
23 © 2011 IBM Corporation
Principles
 The metamodel will never be “complete”
o Start with the most important projects and their analytical needs
o Projects can extend the metamodel for specific needs
o Harvest experience from the projects to corporate metamodel
 Simplicity and maintainability over absolute truth
 Minimize ambiguity and inconsistency
 Base it on TOGAF 9’s content metamodel
 Involve the customer (i.e. the projects)
If a repository should at the same time contain data at conceptual, logical
and physical levels, there will be inconsistencies. In particular, models will
not be perfect for all stakeholders, for all points of view, at all points in time.

“Architecting” in PowerPoint
 Advantages
o Quick and Easy: almost no training necessary
o Availability
o Flexibility
 That’s great, but…
o Alterations are difficult to perform
o Analysis are very difficult to perform: various views (dimensions)
o Inconsistency
o Ambiguity
o Version Control
o Collaboration
o Reuse of assets

Practical Challenges & Advice
 The EA repository will never be the only source of documentation. The metamodel
must take this into account, by, for example, specifying where the documentation
“master data” resides.
o To have control, one must have a single metamodel that describes where all information
resides.
o Strategies for synchronization with those repositories must be put in place.
 It is very difficult to guess what the corporate metamodel should be. It is better to
establish a skeleton and then work with real projects.
 Both, top-down and bottom-up approaches should be used when populating the
repository.
 EA must acquire a critical mass before clear benefits can be observed, first
projects may not see all benefits
 Must have a strategy for keeping content up to date
 Avoid the tool-secretary trap! Instead create a framework where project members
are trained and supported to use the tool themselves.
