It takes a lot of people with many different sets of knowledge and skills to create a book such as this one. Thanks first and foremost to our wonderful contributors. They are experts and leaders in the use of simulation in healthcare education and practice, and we very much appreciate their willingness to share their knowledge and expertise. Thanks to Carla Hall, Managing Editor extraordinaire, and the fantastic Sigma staff, who inspire, plan, nag (when needed), organize, encourage, create, facilitate, and so much more—all to turn an idea into a book that benefits nurses and ultimately their patients.
