The Problem

• The The X Paradigm project is meant to provide guidance in is meant to provide guidance in creating deployments where many systems, new and creating deployments where many systems, new and legacy, speaking different standard protocols, must legacy, speaking different standard protocols, must interoperate to satisfy one healthcare domain. interoperate to satisfy one healthcare domain.

• The immunizations domain was chosen due to its relative The immunizations domain was chosen due to its relative simplicity, existing infrastructure, and the background of simplicity, existing infrastructure, and the background of some authors. The HL7 Service-Aware Interoperability some authors. The HL7 Service-Aware Interoperability Framework (SAIF) provides the theoretical and standards Framework (SAIF) provides the theoretical and standards framework for approaching the project.framework for approaching the project.

Storyboards/Use Cases/Services

• X Paradigm Use Case Analysis Overview• X Paradigm concluded that the X Paradigm concluded that the

Immunization Domain Analysis Model ( (IZ DAM) contained ) contained the most inclusive and recent collection of Storyboards and the most inclusive and recent collection of Storyboards and Use Cases. Use Cases.

• Storyboard narrative Interactions were Storyboard narrative Interactions were cross-referenced with Use Cases. with Use Cases.

• Use Cases were analyzed and Use Cases were analyzed and mapped to existing HSSP to existing HSSP Service Specifications. Gaps were identified for Manage Service Specifications. Gaps were identified for Manage Vaccine Inventory and Manage Reports.Vaccine Inventory and Manage Reports.
