This book is for those who want to use Scrum throughout their enterprise for product development. Right now, you might have pockets within your enterprise that use Scrum, and they are more effective than elsewhere. You are at least partially convinced that using Scrum throughout the enterprise might be a way to make the whole enterprise more effective, but you could use some help in figuring out how to do so. This book is for you.
There are many reasons why your enterprise can't develop and deploy products and systems as rapidly, inexpensively, and with the quality that you would like. You and your staff probably can already list many of them. Scrum won't solve them. Scrum is simply a tool that will relentlessly and ruthlessly expose them. As you try to build product within the Scrum framework, every time one of these impediments is reached, it will be exposed in a somewhat painful way. You can then prioritize it and systematically eliminate it. When the impediments are mostly gone, Scrum is a framework that will enable the product development you desire. And it will continue to be your watchdog against any new impediment or old impediments returning home for a visit.
