5 4 Management & Technology Consultants © 2006 BearingPoint The Reach Agency Established by Irish Government legislation in 1999 and 2000 to: Develop a strategy for the integration of public services Develop and implement the framework for electronic government To radically improve the quality of service to personal and business customers of Government and to develop and deploy the Public Services Broker to help agencies achieve that improvement In particular Reach is to develop and implement an integrated set of processes, systems and procedures to provide a standard means of access to public services, to be known as the Public Services Broker (PSB)." To radically improve the quality of service to personal and business customers of Government and to develop and deploy the Public Services Broker to help agencies achieve that improvement In particular Reach is to develop and implement an integrated set of processes, systems and procedures to provide a standard means of access to public services, to be known as the Public Services Broker (PSB)." The Reach Mission:

26 Management & Technology Consultants Service-Oriented Architectures for E-Government What Weve Learned So Far

27 26 Management & Technology Consultants © 2006 BearingPoint When to Use Standards If they are sufficiently mature Can be based on individual assessment or vendor implementations You understand the parts that are missing or broken The fundamental aspects are not under revision Just because a specification is published doesnt make it a standard Just because a specification is published doesnt make it a standard If they fit the problem youre trying to solve Pay attention to the 80/20 rule Does the benefit justify the cost? are not Technology and specifications are not in the drivers seat Everything should be made as simple as possible, but no simpler – Albert Einstein

28 27 Management & Technology Consultants © 2006 BearingPoint Technology Operational Costs Allow incremental adoption based on ROI for the participants No more big bang deployments SOA means as long as you do the what the how isnt as important Pay attention to licensing and upgrade costs Understand your platform and deployment constraints Be prepared for unexpected adoption rates that could affect TCO Minimize assumptions and dependencies Service implementations should be black boxes Just because a service is deployed here today doesnt mean it wont be deployed in another environment tomorrow Monitoring, diagnosis and manual intervention is critical Operations needs consistent, accurate views of the running system Dont forget about priority manual intervention and build in the mechanisms

29 28 Management & Technology Consultants © 2006 BearingPoint Interoperability Its about the messages Identify the fundamental information used by a business process The data will be around a lot longer than the systems that process it Specify the essentials, let the rest vary Core data elements and their meanings Reliability constraints Invocation interface Think the Internet Embrace loose coupling Tools, technologies and techniques are generally transient Isolate the moving partshide them behind standardized interfaces Minimize centralized controllet the participants own their processes

30 29 Management & Technology Consultants © 2006 BearingPoint Engagement with Government Agencies Dont underestimate organizational dynamics Each agency has a unique personality and way of doing things Encourage collaboration, not mandatory adoption of one true way You can lead a horse to water… Set realistic expectations Early adopters will likely bear the brunt of the costs ROI will be incremental, and generally not immediate Spell out data and process ownership, reconciliation and failure recovery scenarios Offer added value Federated identity management provides access to registered user base Auditing, logging and non-repudiation of message exchanges Offer incremental adoption Agency capabilities are not all equal Essential to deliver capabilities to the SOA quickly and cost-effectively

31 30 Management & Technology Consultants © 2006 BearingPoint Service Implementation Build the right levels of abstractions Easy to make services too fine-grained Dont worry about details not relevant to what the service does Strive for portability Design and build for change Well-defined interfaces between business logic and message transfer Strive for cost-effective scaling Scale out, not up Minimize statefulness Dont accidentally depend on tools and capabilities you dont really need Build a service, not an application The service should be generally useful, not tied to a given requestor
