What is the Justice Information Exchange Model (JIEM) Methodology and Tool?

The Justice Information Exchange Model (JIEM) Methodology is a structured, formally documented approach for defining and capturing information exchange requirements. The overarching goal of the JIEM Methodology is to build consensus about information exchanges among business partners. The JIEM Methodology provides the steps necessary to capture both the content of the exchange (the information being exchanged) and the context of the exchange (who is involved in the exchange, the factors determining when and where the exchange should occur, and what event will happen next).

The JIEM Methodology is premised on the notion that all information exchanges can be described by identifying five dimensions of requirements. These five dimensions are:

1.     Process: A series of logically related events and exchanges that achieve some business purpose or milestone.
2.     Event: Decisions or actions that trigger information exchange.
3.     Agency: Business partners who exchange information.
4.     Condition: Decision points or "gates" that define when information exchange happens.
5.     Information: The content of the information exchanged-the "payload."

JIEM documents additional important requirements, including the priority and frequency/urgency of each exchange. In the future, JIEM will capture critical policy requirements such as exchange privacy and security details.

The JIEM Methodology also supports the concept of reference models. A reference model is a set of information exchanges regarding business functions that are common to most jurisdictions based on the models developed by JIEM users. Reference models allow JIEM users to leverage key exchanges of relevance to their site, reducing the time it takes to develop requirements while producing results that are more consistent with those of other jurisdictions. The existing JIEM reference model is based on the Adult Felony judicial process. SEARCH is adding new reference models to define exchanges commonly found in other environments.

The JIEM Modeling Tool applies the JIEM Methodology and allows users to capture requirements using the five JIEM dimensions. The Tool also supports the definition of "as-is" and "to-be" models, aligning with basic enterprise architecture techniques and supporting the ability to identify information sharing capability gaps. This information can in turn feed into a jurisdiction's strategic planning efforts in order to determine specific projects, initiatives and investments necessary to achieve business goals outlined in a strategic plan.

Between 1998 and 2007, the JIEM Tool was a Web application hosted at SEARCH. SEARCH released JIEM 4.0, based on the Eclipse tools platform, in September 2007. This new platform improves usability and opportunity to integrate JIEM with other off-the-shelf modeling tools (such as UML and XML tools) that industry is actively developing on Eclipse.

JIEM plays a key role in the National Information Exchange Model (NIEM) Information Exchange Package Documentation (IEPD) Lifecycle. The second step in the NIEM IEPD Lifecycle is "Analyze Requirements." JIEM provides an effective way to gather the requirements necessary to construct an IEPD. The JIEM Tool is also integrated with NIEM through the use of component libraries. Component libraries allow JIEM users to use NIEM concepts when defining exchange content.

Access to JIEM, including training, is available at no cost from SEARCH through funding from the Bureau of Justice Assistance, U.S. Department of Justice. Use of JIEM is reserved for those who have completed JIEM training and certification. For more information about JIEM training opportunities, please email jiem@search.org.
