HOW ARE NASA ENGINEERS MOTIVATED? AN ANALYSIS OF FACTORS THAT INFLUENCE NASA GODDARD ENGINEERS’ LEVEL OF MOTIVATION HOWARD ERIC KEA A DISSERTATION Submitted to the Ph.D. in Leadership & Change Program of Antioch University in partial fulfillment of the requirements for the degree of Doctor of Philosophy July, 2008 This is to certify that the dissertation entitled: HOW ARE NASA ENGINEERS MOTIVATED? AN ANALYSIS OF FACTORS THAT INFLUENCE NASA GODDARD ENGINEERS’ LEVEL OF MOTIVATION prepared by Howard Eric Kea is approved in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Leadership & Change. Approved by: Jon Wergin, Ph.D. Chair date Elizabeth Holloway, Ph.D. Faculty Reader date Carol Baron, Ph.D. Faculty Reader date Charles Seashore, Ph.D. External Reader date Copyright 2008 Howard E. Kea All rights reserved This work is dedicated to the memory of my father Andrew Millard Kea, Capt. USAF Who let nothing deter him from pursuing his life’s dream: “To fly airplanes…” Acknowledgments There are many people I would like to thank for supporting me throughout this journey. I had the gifts of listening ears, coaching, cheerleading, shoulders to cry on, and laughter from family members, friends, fellow cohort members, and faculty. I am truly grateful to each of them for encouraging and challenging me to dig deeper, and to slow down when I needed to. Thank you to Dr. Laurien Alexandra, for conceiving and birthing this fabulous program, and for inviting me on this journey and encouraging me along the way. Thank you to Dr. Elizabeth Holloway, my advisor and committee member, for guiding me along the journey, encouraging me along the way, and helping me to get clarity on my dissertation. Thank you to Dr. Jon Wergin, my committee chair, for guiding me to a manageable dissertation topic and allowing me to put it in my voice-- you also make a damn good martini as well! Thank you to Dr. Carol Baron, committee member, ILA mentor, and my statistics instructor, for the many hours on the phone and at your house in helping me to understand my data and introducing me to the “art” of quantitative analysis. Thank you to Dr. Charles Seashore, external reader, for your insightful feedback on my dissertation. Special thanks to Dr. Michael Broom, my coach and ILA mentor, for stretching me well beyond what I thought possible which led me to finding my own voice. Thank you to Cohort 1: Scott, Karen, Mia, Beth, Bruce, Peggy, Miriam, and Bill, we were the nine pioneers who stuck it out to the end. Thank you for the love, support, and life- long friendship. Thank you to my NASA family and particularly to Denise Davis, my boss, for advocating on my behalf for the NASA Study Fellowship that enabled me to complete my dissertation and to directors, Ron Brade and Orlando Figueroa for granting me permission to conduct my i research at NASA Goddard. Thank you to all the engineers who participated in the study and made this work possible. Thank you to my mother for planting seeds when I was a child that education is the key to success in life and to my sister, Dr. Karen Kea for her quiet inspiration. Thank you to my children Chase and Mallory, for giving Dad time to study and for your bright smiles that bring me joy each day. And finally, thank you to my wife Nikki, for sticking by my side through my personal struggles. You are my best friend. This PhD program brought us together and without your unconditional love and support I could not have completed this journey. ii Abstract NASA is an organization known for pushing the envelope of engineering and scientific achievement. It can be argued that engineers working for NASA are intrinsically highly motivated due to the nature of the work and the mission of NASA. This study explores how supervisor behaviors, both intrinsic and extrinsic and demographic factors influence motivation of NASA Goddard engineers in their current environment. Recent Congressional and Office of Management and Budget (OMB) policies, such as full cost accounting, levy strict oversight of project spending. As a result of these policies, NASA engineers must now focus their attention on getting assigned work on funded projects in addition to pursuing technical innovation and creativity. The literature is replete with previous studies on motivation of engineers and scientists. These studies investigated Maslow (1970), Vroom (1964), Herzberg (1971), and Deci’s (1975) theories of motivation. Today, the workplace is much more diverse with regard to race, gender, and age. A web-based survey was used to collect data from a sample of engineers at NASA Goddard Space Flight Center. 260 out of 583 engineers responded to the survey. 238 cases provided useable data for analysis. A hierarchical regression analysis revealed the demographic categories of females and non-whites did not significantly predict the level of motivation of engineers. Age was a significant factor influencing motivation. The age group of 39 and under had less of an influence on motivation and the age group of 40 and over had more of an influence. The over 60 age group had a very significant positive influence on motivation. Other significant factors influencing motivation were: supervisor behaviors, intrinsic factors such as feedback and competence, and extrinsic factors such as benefits, rewards and promotions. The results support the argument that NASA engineers are motivated by getting feedback from their immediate project supervisor, that they feel competent in their jobs, and that the benefits, rewards, and promotions fairly reflect their contribution and loyalty to the mission of NASA. iii TABLE OF CONTENTS Acknowledgments i Table of Contents iv Abstract iii List of Tables vi List of Figures vi Chapter I: Introduction 1 Problem Statement 1 History and Culture of NASA 1 Purpose of and Justification for this Study 10 Personal Connection to the Study 11 Research Questions 13 Description of Terms--Matrixed Employees 14 Organization to be Studied 15 Summary of Chapters 17 What is Motivation? 19 Motivation in the Workplace 22 Leadership and Motivation 24 The Engineering Profession 30 Motivation of Engineers as a Professional Group 34 Supervisor Impacts on Engineer Motivation 39 Previous Empirical Studies on Engineer Motivation 47 Summary 58 Chapter III: Method 61 Design of the Study 62 Study Population and Sample 64 Reliability and Validity 65 Data Collection 66 Data Analysis 67 Summary 70 Chapter V: Results 74 Overall Response Rate 74 Descriptive Statistics 75 Reliability 76 Factor Analysis 77 Regression Analysis 84 Summary 88 Chapter VI: Discussion 90 Summary of the Study 90 Study Limitations 97 Implications for NASA Management 98 Further Study 99 Concluding Remarks 100 iv Appendices 101 APPENDIX A--SURVEY INSTRUMENT 102 APPENDIX B--NASA LETTERS OF APPROVAL 110 APPENDIX C--IRB APPROVAL FORM 113 APPENDIX D--DATA SET 116 APPENDIX E--OPEN ENDED RESPONSES AND COMMENTS 117 APPENDIX F--DESCRIPTIVE STATISTICS 138 References 146 v List of Tables Table 1.1 Demographic Breakdown of Total U.S. Federal Government Employed Engineers 3 Table 1.2 NASA 2007 Engineering Workforce 5 Table 1.3 GSFC 2007 Engineering Workforce 5 Table 2.1 Differences in Vocational Interests between Scientists and Engineers 33 Table 2.2 A Framework for Work Motivation 37 Table 3.1 Variables Predicting Motivation Levels of NASA Goddard Engineers 69 Table 5.1 Sample Size Compared to Response Rate and Weights 75 Table 5.2 Variables with Significant Kurtosis 76 Table 5.3 Reliability of Each Scale 76 Table 5.4 OCQ Scale Factor Analysis Variables 78 Table 5.5 Proj_Supr Scale Factor Variables 79 Table 5.6 Admin_Supr2 Scale Items 80 Table 5.7 JCI_Autonomy Scale Variables 80 Table 5.8 JCI_Feedback Scale Variables 81 Table 5.9 EWS_Competence Scale Items 81 Table 5.10 Pay and Promotion Scale Items 82 Table 5.11 Benefits and Rewards Scale 82 Table 5.12 Policy Scale 83 Table 5.13 Descriptive Statistics for New Variables 83 Table 5.14 Regression Analysis for Motivation Scale of 1 to 7 Using Weighted Data 86 Table 5.15 Regression Analysis for OCQ_Motivation using weighted Using Weighted Data 87 vi
