Consider a healthcare facility with independent software systems for each department. A system engineer is tasked with developing a message exchange system between the departments based on the HL7 Version 2 standards. She begins by describing the interfaces and content exchanged between departments based on SysML interface blocks. The flow properties of these interface blocks are typed by HL7 message types as well as a direction. Next, a SysML internal block diagrams (IBD) of the system is developed. Proxy ports on the parts and the item flows between the ports are used to represent the HL7-based communication between the software systems of the departments, as illustrated in the top figure.

While developing and testing the message exchange system, the system engineer will need to keep track of issues and problems that arise. JIRA is an online tool widely used for this purpose.  The system engineer can view and track issues by message type, using Syndeia™ to create reference connections between the SysML model (left side of lower figure) and issues in the JIRA project (right side).
