EHR SD RM Supporting Requirements/ Architecture Development Cycle PROCESS INPUTS -Required Capabilities -Environments -Constraints EHR SD RM Capabilities - Functions, Information Model Information Exchanges Stakeholder Requirements Definition Functions – Dependencies Conformance Criteria Requirements Loop Function or Service Interface Design Specifications Requirements Analysis Design Loop Architecture Design Test Specifications Verification & Validation Loop Compliancemeans a system provides support for a given standard. Conformanceis a recognition of formal testing, that prove that a system provides 100% support for a given standard. PROCESS OUTPUTS -System Architecture, -System & Test Specifications -Configuration Management Baselines
EHR SD RM Supporting Requirements/ Architecture Development Cycle Stakeholder Requirements Whatis the system supposed to do? Where will the products of the system be used? Under what conditions will the products be used? How often? How long? Who will use the products of the system? Requirements Analysis (“HOW?” using “Action Verbs”) Analyze functions and Services Decompose higher level functions to lower level functions Allocate performance requirements to the functions Architecture Design (Whichhardware/ software elements) Define the physical architecture Each part must perform at least one function Some parts may perform more than one function Requirements Loop • Ensure all requirements are covered by at least one function • Ensure all functions are justified by a valid requirement (no unnecessary duplication) Design Loop • Ensure all functions are covered by at least one hardware or software element • Ensure all elements of physical architecture are justified by a valid functional requirement (no unnecessary duplication) Verification & Validation (V&V) Loop • Each requirement must be verifiable that the solution meets requirements and validated that it meets the user’s needs and expectations. • V&V can be accomplished by: Inspection, Analysis, Demonstration, Test

The HL7 Services-Aware Interoperability Framework (SAIF) SAIF Contains: Enterprise Conformance and Compliance Framework (ECCF) is based on RM-ODP Behavioral Framework (BF) Interoperability Scenarios supporting the RM-ODP Computational Viewpoint Governance Framework (GF) Governance is the overarching policy structure and set of related processes by which a group exercises its authority and demonstrates accountability for accepted responsibilities within a particular jurisdiction. SAIF Principles: Applicable within each of HL7’s three Interoperability Paradigms (IPs), (i.e., messages, documents, and services). Provide support for measurable conformance and compliance. Define appropriate governance structures and processes. Provide support for directly implementable solutions. Address the growing disparity between the various solution sets emerging from HL7. Utilize existing V3/RIM artifacts and expertise to the maximum degree possible.

Call for Participation – HL7 in Rio • We are inviting all interested to participate in the 11th International HL7 Interoperability Conference (IHIC-2010), to be held in Rio de Janeiro, Brazil on May 2010. This time will be the first for IHIC in South America. Following the success of previous IHIC venues in Kyoto(2009), Crete (2008), New Zealand (2007), Germany (2006), Taiwan (2005), Mexico (2004), IHIC2010 aims to serve as a meeting place for more than 30 HL7 affiliates around the world as well as individuals interested in interoperability and standards, to share their HL7 implementation experience and strengthen their shared vision. The paper submissions are invited to show to the international community successful experiences using HL7 V3 and CDA R2 interoperability between informatics applications using standards. Also, results and experiences from the collaborative use of standards are most welcome, especially if they are related to HL7 standards. • Topics of interest include but are not limited to the following: • HL7 implementation experience from regional, trans-regional, or national implementation: • • HL7 v2.x and 3.0 messages • • Clinical Document Architecture (CDA) • • Imaging Diagnostics and DICOM Standard • • Use of HL7 in IHE profiles • • Terminologies, Ontologies and Coding Systems: use of local and international • standards • • Use of other standards in combination with HL7 standards: ASTM, ISO, CEN, etc. • Business Models, regional & large scale deployment: • • Electronic Healthcare Record: from strategy to implementation • • Legal and regulatory issues. • • Epidemiology, disease surveillance and control • • Geographical information systems for population health • • Disaster medicine, emergency management and public health This year, along with the successful “Show me your CDA!” track, IHIC will also incorporate the "Send me your CDA!" HL7 CDA Interoperability Showcase to display basic interoperability of applications using a HL7 V3 and HL7 CDA R2 standards. All submitted papers will be reviewed based on their technical quality and merit by the technical committee and reviewers. Papers that describe research and experimentation are encouraged. All paper submissions will be handled electronically using IEEE format, and detailed instructions on submission procedure will be available on IHIC2010 web pages (http://www.ihic2010.hl7.org.ar/). Accepted papers will be published online. For other information, please contact IHIC2010, (fportila@gmail.com) Important Dates: • Call For papers : November 2, 2009 • Deadline for submissions extended to February 15, 2010 • Evaluation and notification, March 15, 2010 • Camera-papers ready due : April 15, 2010
