Architecture, in the form of systems architecture, technical architecture, data and information architecture, have received a good deal of attention within the information systems (IS) function over the past decade. These architectures have all been considered vital to the success of the systems delivery effort. (Brancheau & Wetherbe, 1986 & 1987; Brancheau et al., 1989; Niederman et al, 1991 ; Janz et al., 1995 ; Zachman, 1987; Sowa & Zachman, 1992; Good & Manley, 1991; Vitalari, 1995; and many others)
The challenge for the decade ahead is to integrate them, along with business architecture, into a comprehensive framework which represents a holistic model of the entire organisation - Enterprise Architecture.
Research along these line has been recommended:
“Rigorous examination of information architecture, can (1) categorize and describe techniques for creating firm-wide information architectures; (2) clarify organizational circumstances in which an information architecture is of greatest value; and (3) link initiation, development, and evaluation of information architecture to technology infrastructure requirements and to theoretical bases for predicting successful enterprise-wide application of IT. Similar research efforts might be directed at solving problems related to strategic planning and organizational alignment.” (Niederman, Brancheau & Wetherbe, 1991 )
This paper attempts to address point (2) above.
One way of assessing the importance of architecture to the IS function is to study “key IS issues ” research.
