An Abstract of a Dissertation Submitted to Nova Southeastern University in Fulfillment of the Requirements for the Degree of Doctor of Philosophy Enterprise Integration Modeling: Linking Enterprise Integration Architecture with Business Strategy Planning By Easton B. Rhodd 2002 The goals for this study were twofold. The first goal was to identify planning variables for linking both organizational and architectural objectives for developing enterprise integration architecture. The second goal was to validate enterprise integration modeling methodology as a viable planning tool for the design, development, and maintenance of the enterprise integration architecture. This lack of linkage at the intellectual dimension level can be characterized as having a dysfunctional effect on enterprise integration strategy formulation and infrastructure development. There is a disjoint between adoption of appropriate information technology in relation to organizational objectives. This includes misapplication of investments in information technology selection and business systems development portfolio, failed information systems projects, architectures that do not support the strategic direction, and the organization's inability to manage change associated with environmental imperatives that impact the firm’s ability to define information technology and systems requirements for competitive positioning. In order to achieve the objectives the author in this research, developed a conceptual Enterprise Integration Architecture Planning Model and Methodology (ELAPM/M) model as the basis for linking enterprise integration architecture objectives and organizational objectives. Research data confirmed the need to effect linkages between organizational objectives and architectural objectives to achieve enterprise integration and validated enterprise integration modeling as the means by which enterprise integration architecture is developed. iii Reproduced with permission of the copyright owner.

Completion of this project would not be possible without my dissertation chair, Dr. John Scigliano. Starting with the idea paper, he provided valuable insights, diligently reviewed all my writings, and freely shared his wisdom, technical guidance, and insistence on quality. It is his drive for un-compromised quality that I found most appealing since this virtue heightened my sense of achieving technical competence. Dr. Levin and Dr. Dringus who served on the committee and patiently read each draft, and did not compromise on the technical and qualitative aspects of this dissertation. To these fine people, I extend my thinks. Ideas grow from interactions with many fine individuals we meet during our daily travels. One individual to whom I am grateful is Dr. Peter Aikin, professor at the Virginia Commonwealth University and friend for seeding the idea for my dissertation project. My thanks go out to associates Emery Hite, John Fmacisconi and Vivian Brown who was kind enough to read many chapter revisions and provided valuable feedback that enhanced this research. Without this resource, the results of this project would not have met the objectives outlined in the dissertation. My wife Dorothy along with my three daughters Colleen, Simone and Lesley-Ann are truly wonderful individuals. Throughout this journey, they collectively and individually, shared in some of my most challenging moments and in their own way, lifted my confidence and spirits thus keeping me on track. Their understanding, kindness, and continual support is unparallel; providing humor when needed, offering perspectives not considered, and dispelling any notion of quitting still resound even after reaching this final place. To them I say you earned this prize. I must also express my sincere gratitude to my Dad, who many times over the course of this project counseled me on the virtue of patience. It is not uncommon to want to rush when your environment is ever changing at a rate you cannot comprehend. His perspectives having forged over time and have seen many changes, helped me to understand that there will be some events I cannot control and time must have its role in the outcome. I am also honored to have had my brothers, Keith and Victor, read, critique, and challenge me along the way. Their comments and suggestions were invaluable.
