vi PREFACE

V. Thiyagarajan of Oblix Inc., and Pirasenna V. Thiyagarajan, Sun Microsystems,
Inc., supplied information on the security aspects of technology and ERP. Pro-
fessor Arun Pennathur helped in identifying the software available for question-
naire design, data collection, and data analyses. The help of all these individuals
is very much appreciated. My sincere thanks also go to Tom Moellering of SPSS,
Inc., who responded promptly to my request for the latest 11.0 version of SPSS
software programs for data analysis.
My thanks are due to several other individuals as well. Professor Elizabeth Bar-
clay of Oakland University, Rochester, Michigan, reviewed the third edition and
suggested some changes for the revision. Professor Metin Cakici of Isik Univer-
sity, Istanbul, pointed out some inaccuracies in the formulas in the chapter on
sampling in the third edition. Thanks to him, these have now been rectified.
Mr. Narayanan Pennathur patiently read the draft versions of the chapters and
significantly improved the language and style of writing. Mr. A.R.C. Sekaran
helped in getting the manuscript ready for publication. My appreciation to both
these individuals. My heartfelt thanks to Sudha Pennathur, President of the House
of Pennathur, for an update on the case study in the last chapter and for pro-
viding another case for the book. Her help is deeply appreciated.
I expect that students and instructors alike will enjoy this edition. Students
should become effective managers, helped by the requisite knowledge and skills
acquired by the study of this book. The Instructor’s Manual that accompanies
this text will be a good additional teaching aid for teachers. I hope both the
instructors and the students will find this book useful.
