In order to get the most out of this book, it's preferable that you have some experience developing products or services, besides knowing the basics of UX. It might be good as well if you have some knowledge in using designing tools. Although this book will show you a few great tools to be used, this is not a book focused on tool or software tutorials. Be prepared to use not only online tools, but papers, sticky notes, pens, paper templates, canvas, whiteboards, and drawable walls. Last but not least, be open for a more business approach of getting the best results of fixing bad UX centered on your user.
