Aetna - Enabling a Digital Strategy that Fits the Healthcare System Around the Consumer Using BPM SOA



Speakers: ...

Arup Datta, Prolifics
Joseph Arnold, AETNA

Aetna is making connected health care systems a reality and empowering consumers to live a healthier life. Key to the strategy is enabling new mobile technologies and partner integration. To enable this transformation, Aetna is implementing a BPM SOA center of excellence (COE) that will enable their business to rapidly orchestrate and integrate their systems & services in order to seamlessly provide users with data & IT resources with faster integration, lesser cost and higher return. We will showcase the BPM COE approach and the components being used to build it out. Aetna's Enterprise Architecture will ensure separation of business rules from data integrity rules and provide enterprise level decision services. This BPM architecture will also enable to integrate with Aetna's DataPower, Enterprise Bus and mainframe systems to communicate with the Data Access Services layer. The solution involves using IBM tools like ITCAM for monitoring, Service Registry and eXtreme Scale for caching needs.

  • 11. Aetna Inc.Enterprise Architecture Common Message Model (CMM) • One Enterprise Common Message Model • Every back-end source maps to CMM • Reconciles different names from back-end sources • All responses drawn from CMM • Consistent naming across responses • Designing to the CMM has advantages: • Map new data sources to CMM; available to current logic and responses • Orchestration and process logic uses CMM – enable reuse • There are implications to the CMM • Must be governed, managed for consistency • Consumers must break ties to back end structures 11

  • 14. Aetna Inc.Enterprise Architecture Impacts / Things To Do Different Programming to interface, not to implementation • Design early • Socialize the interface with consumers • Publish mock service/objects to speedup the process Externalize business rules from application logic • Business Rules as a Service Document & socialize • Standardized terminology, verbs, nouns, meaning • Common Message Model 14
  • 15. Aetna Inc.Enterprise Architecture Summary 15 • Rapid and continuous change is necessary to stay in business • IT must enable the delivery of data and services to consumers where and when needed and in a format they want • BPM technology provides a toolset to enable incremental movement towards your digital strategy • Broad capabilities for creating digital building blocks • Advance at your own speed • Supported by a solid roadmap

  • 19. Aetna Inc.Enterprise Architecture Technical Architecture – Highlights 1 Architecture Highlight # Comment 1 Process Server is a component of IBM's BPM suite. It provides the run- time environment for business processes and services developed using Process Designer and Integration Designer. 2 Process Center is the repository of business processes and business services. Process Center supports versioning of processes and services. 3 Integration Designer is the development/debug/unit test environment for developing business services. 4 Process Designer is the development/debug/unit test environment for developing business processes. 5 A Business Service is typically a short running process (micro-flow), mediating or orchestrating one or more services. Business services can use built-in adaptors and accelerators to speed up the development process. 6 Business Process is typically a long running (macro- flow) process involving one or more workflows, business process, business services and business users. It may typically include a user interface (Coach). Business Processes typically monitory business or workflow activity. 7 Process Server may support both SOAP (5) and REST(7) model. 8 WSRR - Websphere Service Registry and Repository provides * run-time WS-Addressing attributes * WSDLs 19
  • 20. Aetna Inc.Enterprise Architecture Technical Architecture – Highlights 2 Architecture Highlight # Comment 9 New services/processes developed using BPM 10 Application Services / Cobol APIs / Stored Procedures 11 The technology stack may include a rules engine such as IBM ODM. 12 The technology stack also includes a remote cache using IBM eXtream Scale. 13 Business Monitor can be used to monitor business events published by processes running at Process Server and at other servers. The monitor can also publish the events to PS to trigger additional processes. 14 SMTP - simple mail transfer protocol. BPM can use SMTP to email any notifications to email recipients. 15 Audit and Logging Services provide shared enterprise-wise audit and logging capabilities. 16 IBM Tivoli Composite Application Manager (IT CAM) may be used to monitor the health of BPM server components and diagnostics messages from EDB services. 17 Clearcase will be used for code asset management, version control and code promotion from dev to qa to production. 20
