3.5 State of the Practice, Market, and Art
Popular methodologies at present fall into the following broad categories:
l
Building new applications by using OO concepts [Booch 1994], and [Rumbaugh 1994]).
l
Building decision support systems such as data warehouses [Inmon 1994].
l
Platform specific methodologies such as for CORBA [Mowbray 1995], [Otte 1996] and OSF DCE [Rosenberry 1993].
l
Migration methodologies for transitioning of legacy applications to new platforms [Brodie 1995], [Sneed 1995], and [Desfrey 1996].
l
Business process reengineering (BPR) methodologies that tie BPR to IT architecture [Henderson 1990], [Keen 1993], and [Luftman 1993].
However, no methodology at present attempts to tie all these methodologies into an overall framework that can be used for building new applications and dealing with legacy applications in OCSI environments. We have attempted to accomplish this in this chapter. Naturally, the current state of the practice and market for such methodologies is sparse. However, this is an area of potential research. The key research question is: Can a systematic sequence of steps be defined that takes into account the wide range of new and existing application issues in the evolving IT infrastructure? There is some recognition of this work in the marketplace (see the sidebar "An Expert System for Generating Methodologies").
