DESCRIPTION BOOK : ServiceNow is a powerful ITSM (IT Service Management) software solution with a massively configurable back-end. One of the greatest benefits of
ServiceNow is that it lets you do just about anything you could want to do, to suit the needs of your business. On that same note, one of the most dangerous things about
ServiceNow, is that it lets you do just about anything! With such freedom and capacity for customization, comes risk, but that risk is not without great reward, which you can
realize with a strong understanding of best-practice.DescriptionThe goal of this book is to explore the pitfalls, standards, and best-practices that most ServiceNow ITSM
developers either learn the hard way, or never learn at all. These are the things that every developer wishes they knew from day one, and which - once learned - will make
you a more effective and efficient developer. This book will teach you how to avoid pitfalls, and empower you with knowledge that will allow you to build much more robust,
resilient, powerful, and efficient solutions within the platform. Having an understanding of why a given standard is what it is (and why it’s important), will not only make you
more likely to adhere to it, but will empower you to apply the logic and underlying concepts behind those standards to other areas of the platform and development. It'll
make you a more effective administrator, developer, or architect. That’s that spirit in which this compendium was written: Teaching and explaining, not simply listing out a
series of arcane edicts under the heading of “best-practice”. The ServiceNow Development handbook will serve to boost your knowledge, your confidence, and your career.

ITSM development career would find the information in this handbook useful. However, this is a condensed “developer guide”, and not a complete ServiceNow training
course. If you are just starting out your ServiceNow development career, consider reading the more beginner-friendly "Learning ServiceNow, Second Edition" (ISBN-13: 9781788837040) first. You can find Learning ServiceNow at http://lsn.snc.guru/ Note: This book's contents may be updated slightly over time, as new information becomes
available. This is to prevent you from having to buy a new edition of this book, every time ServiceNow changes something about how their platform works, or for every minor
addition to the contents. You can find details on the changes at http://changelog.snc.guru/. For this reason, we've made it so that if you buy the paperback version, you can
get the Kindle version at a drastically reduced price, and can update your Kindle version for free whenever new content is available, by going to http://update.snc.guru/. Read
