راهنمای توسعه ServiceNow: مجموعه‌ای از دستورالعمل‌ها و بهترین شیوه‌ها برای توسعه‌دهندگان ServiceNow جلد اول

Whether you're still suffering from "impostor syndrome", or you feel like the top dog on your development team, I hope that you'll find this book helpful for your ServiceNow career. I've written this book not just to be a guide for individual developers, but to be the sort of development guide that an entire team can reference and standardize around, in order to keep their environments consistent. While it doesn't contain strict rules about how to do everything (some things are up to the developer's preference or a team's internal standards), it does outline the best-practice guidelines that everyone should follow, and it points out those standards that should be agreed upon by a team.
