I want to recognize the continuous support I have received during my academic career at the Department of Industrial Engineering of the University of Chile. I have found a very good environment for my creative efforts in this academic unit, including the ideas of Business Engineering, theme of this book, and the Master in Business Engineering that I designed and implemented here.
I also wants to deeply thank the hundreds of students that have worked in my academic projects, several of them identified in the text when their work has been cited, in trying to put to test my ideas in the real world, which is what any engineering discipline should do. They have had a very positive disposition to test innovative proposals, providing the laboratory I needed to prove that they work. This testing would have been not possible without the collaboration of several private and public health care organizations that have been willing to act as research subjects; many thanks to all of them.
