B. Diane Blackwood has worked as a consultant implementing Business Intelligence and Corporate Performance Management (BI and CPM) solutions since 2005. She is currently employed by Strafford Technology Inc., a Business Intelligence consulting firm (http://www.strafford.com/Technology/). She has extensive experience in multiple industries (including micro-electronics, heavy equipment manufacturing, medical, legal, and various retail industries) implementing BI and CPM solutions. In 2010, she worked with El Camino Hospital by creating data warehouse/data marts to feed QlikView, a "social business discovery" software solution. Diane worked closely with Dr. Michael Gallagher, former Director of Informatics at El Camino Hospital, whose enthusiasm for the uses of QlikView in analyzing the hospital and medical data "infected" her.

In 2013, Diane Blackwood wrote Instant QlikView 11 Application Development, Packt Publishing. Diane has also written several biographic encyclopedia articles, including articles on Charles Babbage, Erving Goffman, and Isaac Asimov.

Steve Dark was a SQL Server/MS ASP developer, building web-based reporting solutions until he was shown a demo of QlikView. Soon after this epiphany, Steve left his previous employer to set up Quick Intelligence, a consultancy focusing entirely on QlikView and delivering Business Intelligence solutions. Preferring to stay at the coalface, Steve spends the majority of his time with clients by building QlikView applications, managing QlikView deployments, and running projects.

He will be never tired of showing QlikView to new users and seeing that "jaw drop moment". Steve is active on the Qlik Community and other social media sites by sharing his enthusiasm for QlikView and assisting other users. Through his blog he shares tutorials, examples, and insights about QlikView (you can read it at http://www.quickintelligence.co.uk/qlikview-blog/).

Steve has been on the technical review team for QlikView 11 For Developers, QlikView 11 For Developers Cookbook (also by Stephen Redmond), and QlikView Scripting. All of these titles are published by Packt Publishing.

Barry Harmsen is an independent Business Intelligence Consultant based in the Netherlands. Originally from a background of traditional Business Intelligence, data warehousing, and performance management, in 2008 he made the shift to QlikView and a more user-centric form of Business Intelligence.

After switching over to QlikView, Barry has completed many successful implementations in many different industries, ranging from financial services to telecoms, and from manufacturing to healthcare. Barry's QlikView experience covers a wide variety of roles and subjects, including requirements analysis, design, development, architecture, infrastructure, system administration, integration, project management, and training.

In 2012, Barry co-authored the book QlikView 11 for Developers, Packt Publishing. This book quickly established itself as one of the best ways to teach yourself QlikView. Barry is also one of the core speakers at the Masters Summit for QlikView. This three-day conference for QlikView developers covers advanced topics, and is designed to take your QlikView skills to the next level.
