IMPLEMENTING BUSINESS-TO-BUSINESS ONLINE REVERSE AUCTIONS BY LOAY SEHWAIL Bachelor of Science University of Jordan Amman, Jordan 1999 Master of Science Oklahoma State University Stillwater, Oklahoma 2001 Submitted to the Faculty of the Graduate College of the Oklahoma State University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY July, 2006 COPYRIGHT BY LOAY SEHWAIL JULY, 2006 ii IMPLEMENTING BUSINESS-TO-BUSINESS ONLINE REVERSE AUCTIONS Dissertation Approved: Dr. Ricki G. Ingalls Dissertation Advisor Dr. David B. Pratt Dr. Camille DeYong Dr. William D. Warde Dr. Dan Tilley Dr. A. Gordon Emslie Dean of the Graduate College iii ACKNOWLEDGEMENTS With deep gratitude, I extend my sincere appreciation to the members of my dissertation committee: Drs. Ricki G. Ingalls, Camille DeYong, David Pratt, William D. Warde, and Dan Tilley, who provided me with knowledge and encouragement to help make my dream become a reality. I really thank my committee for all the meetings, endless intelligent conversations, and debates. You have taught me the meaning of research. I am particularly grateful to my chair, Dr. Ricki G. Ingalls, who has affected my life in many positive ways, for his friendship, guidance, and support from the first day we met. I would not have been writing this acknowledgement without his mentoring, support, and friendship. Thank you Dr. Ingalls. Special thanks must go to the Institute of Supply Management (ISM) for its support in providing the contact information for the survey sample. Additionally, I would like to recognize Dr. Rick Boyle for his help, cooperation, and fast response to any inquiry or question. During this journey of research, there are many people who, like lamp posts, stood beside the road at different angles, appeared at different moments, and guided me all the way to where I am now. Without their guidance and encouragement, I would not have been able to make this journey. Thanks to all of you. iv Without the support of my family, none of this would have been possible. I dedicate this dissertation to my role model in life, my father, Munir, who taught me integrity, honesty, and the importance of higher education, and to my mother, Sabiha, whose spiritual support has been encouraging me since the day I was born. I also dedicate this dissertation to my sister, Lama, and my brothers, Feras and Tareq, for their unconditional love and support. My family contribution to my success cannot be quantified or described. Finally, I gratefully acknowledge my wife, Yen-Ping Leow-Sehwail, who provided ongoing support and encouragement. To my wife Yen-Ping: without your support, in every possible form, I would not have been able to do this. Please know that I am truly grateful to you, and that this achievement would have been a lot more difficult without you. I love you. v TABLE OF CONTENTS CHAPTER 1: INTRODUCTION 1 1.1 Overview 1 1.2 Problem Statement 3 1.3 Research Purpose 7 1.4 Contribution of the Research 8 1.5 Outline of Dissertation 10 CHAPTER 2:
