As with any project of this size, there are a number of people who helped support this book. First of all, we would like to thank Anthony Deighton and Donald Farmer for their vision of Qlik^® Sense and their executive support for this project. Additionally, we would like to thank Arthur Lee and the Product Management team at Qlik who supported the technical review of this book.

We would also like to thank all the Qlik employees that joined us over the last 3 years at customer sites to help solicit feedback on Qlik Sense. These people include Jodi Antoni, Pierce Barber, Adrian Bereanu, Chris Brennan, Sean Donovan, Jeff DeAngelis, Dan English, Vinay Kapoor, Terry Kavouras, Mark Latessa, Arthur Lee, Erik Lövquist, Kevin Schulz, and Elif Tutuk. Thank you for sharing your time, knowledge of Qlik products, and customers. This book could not have been written without the hundreds of hours of conversations with customers and partners.

The last four chapters of this book are based on the hard work of the Qlik Demo team. These applications and new approaches to solve these business problems were created by Michael Anthony, Chuck Bannon, Alexander Karlsson, Jennell McIntire, Apeksha Patak, and Arturo Muñoz. Thank you for allowing us to bring life to your applications in this book.

Additionally, we wish to thank the Qlik legal team of Deborah Lofton, Alice Hume, and Heather Rossman for creating the legal framework that allowed us to explore Qlik Sense concepts with customers and partners. Also, we wish to thank the Social Influence and Reputation Management team of Maria Scurry and Toni Iafrate for their support and helping get the word out both internally and externally on the value of this project.

Finally and most importantly, we would also like to thank the companies who have contributed their time, resources, feedback, and passion for Qlik products for more than 3 years, which helped uncover the value of Qlik Sense in their organizations.
