This is a simple, easy-to-understand guide for anyone who wants to learn the Agility concept and the Scrum framework. It covers the underlying concepts and principles, along with Scrum roles and responsibilities, events, artifacts, and scaling approaches, as well as common practices and techniques. 1 Instead of praising Agility, the book focuses on understanding the real meaning of it in a straightforward and consistent way and reviews the types of projects where it may work and where it may not. This foundation will help you find your way in real world daily problems. 2 The book is a complete guide to the core Scrum framework, based on the Scrum Guide (Nov 2017 edition). It covers all roles and responsibilities, events, and artifacts, with a short section about scaling Scrum. 3 There's a chapter on eXtreme Programming, which has been used as an excuse to explore some of the most important Agile practices and techniques, such as Test-Driven Development and Pair-Programming, in an integrated way. 4 The fourth chapter is an overview of the DSDM(R) methodology, which is mainly focused on its approach to managing scope and fixed-price contracts in a structured way. 5 There's an overview of Kanban and ScrumBan in the last chapter. This book is aligned with the EXIN Agile Scrum Foundation certification program.
