5. CIMS Why SOA “Today’s IT architectures, arcane as they may be, are the biggest roadblocks most companies face when making strategic moves.” –McKinsey “Flexible IT, Better Strategy” “Today’s IT architectures, arcane as they may be, are the biggest roadblocks most companies face when making strategic moves.” –McKinsey “Flexible IT, Better Strategy”

6. CIMS Why SOA  Today many IT infrastructures are rife with hard-wired connections that enable applications both in and outside of the enterprise to communicate. N * (N-1) connections  However, this hard wiring makes it difficult for companies to adapt business processes to changing needs and market conditions.

7. CIMS Why SOA  A recent survey of top Global 400 companies revealed  CEOs recognize that in order to quickly respond to increased globalization, economic volatility and drive growth they need a more responsive IT organization that can quickly adapt to changing business priorities;  an IT organization that is tightly aligned with business strategies in a cost effective manner;  and an integration environment that is secure and well managed.  Gartner expects that by 2007 in order to address these business challenges, most enterprises will have started down the path of enterprise-wide SOA.

8. CIMS Why SOA N connections  SOA leverages an organization’s existing investment by taking advantage of current resources, including developers, software languages, hardware platforms, databases and applications.  Organizations that properly used SOA achieved a 40- percent gain in development resource use, reduction in cost, reduction in risk and eased technical support management and monitoring.  The reduction in cost is exponential as the library of enterprise components grows.

11. CIMS System construction  The construction of SOA-based enterprise collaborative management system mainly can be divided into three stages:  Collaborative modelling Multi-views business modelling describes enterprise business MDA technology is used Business model is transformed into platform-independent business collaborative model Platform-independent business collaborative model is mapped into platform-specific business collaborative model

12. CIMS System construction  Service oriented information system construction Software modules in multi-enterprises information system are identified, encapsulated and published into services Build service components libraries The services in these libraries can be composed and choreographed  Collaborative operation and evaluation In the process of system operation, the performance of enterprises business process is monitored, analyzed and optimized by workflow management system.

17. CIMS Collaboration modes  Collaboration refers to four elements  Process  Role  Service  Data  Collaboration can be classified into collaboration between any pair of process, role, service, data:

18. CIMS Collaborative meta-model  Meta-model helps to establish an environment in which business knowledge can be captured and business rules can be traced from their origin be traced from their origin  It forms the foundation of collaborative modeling  Based on MOF, existing workflow meta-model

19. CIMS Collaborative modeling  Collaborative business model need to support complex collaboration relationships  Reflect enterprise business requirement  Keep the consistency between collaborative business model and business requirement  Model mapping method is used

22. CIMS Workflow in Service-Oriented Environments  Workflow in service-oriented paradigm presents some new characteristics:  Services are implemented by workflow  Workflow is just another kind of services  There are multiple processes running at the same time They communicate with event/messages and share the common resource or data  The processes change dynamically along with the change of services
