2. IBM CEEMEA SOA SWAT Team Johannesburg, Aug. 21, 2008 2 How Do You Support a Business Process in a SOA? To Start with, you need Services……  Inventory Analysis -Business processes are made up of individual tasks -What services are needed to perform these individual tasks? -Where do these services come from? Start by Comparing What You Need to What You Already Have …….

3. IBM CEEMEA SOA SWAT Team Johannesburg, Aug. 21, 2008 3 Services Operational Systems People Business Process Connectivity (Enterprise Service Bus) Portals for People interacting with systems and processes Data Registry Application Content External Dashboards for People monitoring business KPIs and system performance SOA Solution Layering & Reuse Business View IT View Reuse of existing IT Assets Reuse of (existing) Services

4. IBM CEEMEA SOA SWAT Team Johannesburg, Aug. 21, 2008 4  Existing business logic is among the most valuable assets a company owns  It is 5X less expensive to reuse existing applications than to write new applications from scratch*  Reusing proven, time-tested applications results in significantly lower risks and faster time to market  Maintenance overhead shrinks with greater use of proven and tested code for common functions * Software Productivity Research (SPR) Business Value of Reuse – enabled by SOA

5. IBM CEEMEA SOA SWAT Team Johannesburg, Aug. 21, 2008 5 Service-enable existing assets Reuse high-value assets in more flexible ways Three sources of Services Consume external services support commodity tasks with externally provide services Create new services from scratch Fill in gaps in portfolio by creating new services

6. IBM CEEMEA SOA SWAT Team Johannesburg, Aug. 21, 2008 6 1)Reuse Existing Services Service enable existing IT assets and make better use of past IT Investments  Identify legacy assets to be delivered into reusable services  Lower risks and faster time to market reusing proven, time-tested applications  Eliminate expense, confusion, and risk associated with redundancy  Make services / systems accessible to a broader pool of users  Combine services that come from several sources and treat them as composite applications

IBM CEEMEA SOA SWAT Team Johannesburg, Aug. 21, 2008 8 2) Consume externally delivered services Outsource commodity services to others  Identify externally available services that can more efficiently be delivered by a third party  Focus your resources on your own core competencies  Use e.g. IBM’s SOA Business Catalog: www.ibm.com/soa/soabusinesscatalog www.ibm.com/soa/soabusinesscatalog

9. IBM CEEMEA SOA SWAT Team Johannesburg, Aug. 21, 2008 9  Service Design  An iterative design and incremental development employing modeling, design and integration patterns  Using visual tools to simplify the design and construction of services orientation  Ensure interoperability with other environments to prevent vendor lock-in  Service Creation  Create services from any code base (J2EE,.net) on any platform  Seamlessly incorporate external services into overall business process  The service provider provides secure, hands-off services delivery 3)Create new Services from Scratch: Fill portfolio gaps with new services

10. IBM CEEMEA SOA SWAT Team Johannesburg, Aug. 21, 2008 10 Methods for Service Design Component Business Modeling (CBM) A methodology to identify and address a range of business and technology needs by translating each component to its business value (e.g. contribution to business performance) by assessing the return on investment/cost for each component by defining transformation priorities Service Oriented Modeling and Architecture (SOMA) A method to transform a Business Architecture to an IT Solution Architecture through 3 phases: identification, specification and realization of services SOA Governance and Management Method (SGMM) A method to establish an SOA that delivers sustainable business value (covered in governance section) PlanDefineEnableMeasure

12. IBM CEEMEA SOA SWAT Team Johannesburg, Aug. 21, 2008 12 Summary  Adopting reuse requires a cultural change, no more silos.  It costs more to develop a reusable asset, but the return will be greater for the customer, including increased quality and an increase in long-term productivity.  Enforcing governance, management support, and pushing down reuse costs are success factors for companies adopting a reuse strategy.  There are three sources of reuse, each with their own benefits; -Service-enabling existing IT assets – allows a customer to reduce redundancy -Consuming external services - focus on core competencies -Creating new services from scratch - leverages open standards  Rational Asset Manager is used to manage and govern development assets, including services.  WSRR is used to govern runtime service assets.  Rational Method Composer allows a customer to define their reuse process and governance controls.
