IIIRM - The Basic Concepts


Traditionally, an application was limited to a single platform on the premises of the enterprise. The interaction with outside world (if any) was too little to be organized. Now, things have changed. Any application is spread across the world. It has a lot of information passing around the world. An important aspect for such an architecture is the "boundaryless information flow". The IIIRM (Integrated Information Infrastructure Reference Model) deals with these aspects of the Technical Reference Model. In that sense, the scope of IIIRM is a subset of the TRM. But, now, it is too huge to be just a part of the TRM.

The IIIRM (Integrated Information Infrastructure Reference Model) deals with these aspects of the Technical Reference Model. In that sense, the scope of IIIRM is a subset of the TRM. But, now, it is too huge to be just a part of the TRM.

The IIIRM has two main components:

  • Taxonomy - This defines the terminology. It describes the components; and a provides conceptual structure of an integrated information infrastructure.
  • IIIRM Graphic - A visual representation of the taxonomy. It details the relationship among the various components described by the taxonomy.

The ADM does not directly depend upon the IIIRM - there is no phase of the ADM that directly refers to the IIIRM. But, the IIIRM makes a valuable contribution to the TRM.

Boundaryless Information Flow


Repeated again and again by the open group, Boundaryless Organization does not mean there are no boundaries - but the boundaries are permeable.

Traditionally, an enterprise had different departments - of specialists - that worked sequentially on any given task. A given task moved from one department to another, where each department added value as per its capability. This finally led to the completion.

But, such a model is slow and cannot be effective any more. Today, speed, flexibility and responsiveness of an organization are important. Over the years, the industry has identified an effective way of handling such a problem. Instead of the task passing along the que of departments; we build a team of individuals from each speciality, that works on the task at a time. This reuses most of the existing IT infrastructure. But, to enable this, the individuals should have simultaneous access to the information.

The operational efficiency of the enterprise could improve significantly with this. This can improve the enterprise processes (internal as well as external). But such a solution is possible only if

  • Information is integrated - different and potentially conflicting pieces of information are not distributed throughout different systems
  • Access is to that information is integrated - so that staff can access all the information they need and have a right to, through one convenient interface

The infrastructure that enables this vision is termed the "integrated information infrastructure"

A simple approach to such an integrated information infrastructure is an "enterprise portal" that gives integrated access to the right information to the right person - via a simple web interface.

This describes the Interoperable Enterprise Business Scenario.

The III-RM depicts the major components required to address the Boundaryless Information Flow problem. It can help the architect in task of identifying newer disruptive technologies and their impacts. It provides insights related to the needs for Boundaryless Information Flow in enterprise environments. The provides rules and standards that can assist in leveraging solutions and products within the value chain.
