Abstract

John A. Zachman at IBM Corporation has postulated an Information Systems Architecture composed of three parts: a series of models for data, a series of models for processes, and a series of models for communications. Zachman's models include a 'Business Model' or conceptual design for each of these information system areas. Conceptual design for data (Entity-Relationship diagrams, normalization, etc.) is well documented in the literature. Much research has also been done in the area of conceptual design for processes. Most of it on development methodologies and programming language design. Very little consideration has been given to the conceptual design of communication networks. This paper will examine why we need conceptual communications design and what should be included in a conceptual model for communication networks.

In any business communications channels and needs exist which may or may not be met by present communications hardware and software. In order to determine accurately what new networks or additions to existing networks will best meet the communications needs of the business, these needs must first be uncovered. The creation of a conceptual model of an organization's existing communicators and communications paths aids analysts in discovering the logical communication structure inherent in the business. Once this existing network is understood it can be used to make design and implementation decisions. In this way communications hardware and software can be acquired or developed which will support actual business needs.
