“Big Data” is discussed with increasing importance and urgency every day in boardrooms and in other strategic and operational meetings at organizations across the globe. This book starts where the many excellent books and articles on Big Data end—we accept that Big Data will materially change the way businesses and organizations make decisions. Our purpose is to help executives, managers, and counsel to better understand the interrelationships between Big Data and the laws, regulations, and contracting practices that may have an impact on the use of Big Data. In each chapter of the book, we discuss an area of law that will affect the way your business or organization uses Big Data. We also provide recommendations regarding steps your organization can take to maximize its ability to take advantage of the many opportunities presented by Big Data without creating unforeseen risks and liability to your organization. This book is not a warning against the use of Big Data. To the contrary, we view Big Data as having the most significant impact on how decisions are made in organizations since the advent of the spreadsheet. Instead, this book is designed to (1) help you think more broadly about the implications of the use of Big Data and (2) assist organizations in establishing procedures to ensure or validate that legal considerations are part of their efforts to harness the power of Big Data.
