Cristina Nicolas Lorente has been working with Dynamics NAV since 2005. She started in the ERP world as a developer but soon evolved into a complete Dynamics NAV professional, performing all the tasks involved in a Dynamics NAV implementation, such as consultancy, analysis, development, implementation, training, and support to end users. When Cristina started developing solutions for Dynamics NAV, she had no idea about accounting or about any kind of business workflows. They don't teach that kind of thing in a technical university career. Soon, Cristina discovered that it is important to know the set of tools used but even more important to understand the meaning of whatever you develop. Without knowing the accounting rules, practices, and legal requirements, it is impossible to develop useful accounting functionalities even if you are the best developer. Only when you fully understand a company's process will you be able to do the appropriate developments. With this in mind, Cristina has taken courses on accounting, warehouse management, and operations management. She is also willing to take courses on any other company-related topics. Cristina thinks the best way to learn is to teach what you are learning to someone else. She has actually learned almost everything she knows about Dynamics NAV by responding to user questions on Internet forums, writing a blog about Dynamics NAV, and of course, writing the book you have in your hands. When you have to write about something, you have to experiment, try, investigate, and read. It definitely is a great way to learn.
