Baseline SOA Adoption
Assessment Exercise
Applying structure to the change management task
Strategies, Techniques, Framework
A working session, guiding participants through elements of an SOA
adoption planning process to illustrate a framework for managing
the transition to SOA. The session will commence with an
assessment exercise – to help participants understand their current
SOA maturity level, and then introduce by example the techniques
involved in SOA capability planning

Strategic SOA
 Analogous to a manufacturing and assembly environment
 Classes of service have appropriate, repeatable processes
 Mature architecture and engineering processes and practices
 Formality over policy implementation to ensure implementation of both
business requirements and architectural policies
 Manage outcomes that are fit for purpose, deliver future flexibility, utility and

SOA Maturity Assessment

The graph below indicates the initial maturity assessment of the SOA with respect to:
•
Current state assessment
•
Situation after in-flight initiatives have run (a 1 year time horizon)
•
A target state proposed for the enterprise (a 3-5 year time horizon)

1 year
outlook
Current State
No consistent enterprise wide reference
architecture for re-use exists although
different elements are being developed in
different parts
Evidence for Maturity
• Some definition of terms locally
• Recognition that architecture is more than just IT
• Reference architecture defined in parts
• Canonical data models exist
• Have some automatic enforcement of architectural
rules
• Some policy definitions written
• Recognition of need for service contracts
Target
state
1 year outlook
Work is planned on taxonomy over
the next year
Target State (3-5 yrs)
See next slide
Evidence for Immaturity
• Lack of awareness of a reference architecture and doubts about its
usability expressed
• Confusion about terminology e.g. no unified definition of a service
• Architectures weren’t consistent across SOA domains
• No single semantic model in place
• Service contract definitions not written or implemented
• Policy definitions not written at business governance level or
consistently enforced
• Low visibility of links between business drivers and architectural
plans
Interview Quote: “Have 5 different capability managers who are doing their interfaces in 5 different ways!”

Integration
Target State Justification
A defined and stable state for the
architecture is considered be
optimal. The more mature state –
mandated – may be inflexible
given the enterprise’s disparate
businesses
Outcomes
Reference Architecture: consistent, layered architectures
across SOA domains enforced in a consistent manner and
widely adopted
Consistent approach enables reuse and drives
productivity through standard approach to solving
complex problems. Layered architecture reduces
dependency and increases adaptability
Taxonomy/Canonical Data Models: consistent use of
service-based terminology across areas. Architectural
classifications and Functional classifications in place. A single
semantic model, against which all services are mapped
Allows management of complexity; easier and
faster to construct compatible end-to-end
solutions
Service Contracts: Rich service specifications and contracts
implemented including SLAs. Procurement agreements
include architectural constraints and obligations
Reduced testing costs. Consumers have
guaranteed service levels.
Greater agility due to ability to modify, extend
and improve services independently if contracts
are unaffected
Modularity: Well-defined boundaries between products and
capabilities. Legacy applications reengineered and
componentised
Sample
Increased speed of change (due to reduced
horizon of change), easier to manage complexity
and better accountability

managed to reduce proliferation of
