Report
Chris Henderson has designed a brilliant introduction specifically for busy leaders who need to quickly get to grips with their team. His introduction gives a convincing diagnosis of the problem of modern leadership and offers a framework that is both simple to adopt but also rich in potential. The Jump! Methodology centres around six key conversations that leaders need to have with their teams. The book gives accompanying narrative and practical tools for each of these six conversations: Ambition, Relationships, Priority, Accountability, Delivery and Learning.
Although this book rewards the quick dip approach (with superb diagrams, well laid out boxed highlights and a comprehensive toolkit annex) Im deeply impressed with the quality and clarity of thinking in this book, and convinced that it merits more careful detailed reading.
Id recommend this book for busy leaders who want a simple framework to help them get to grips with their teams but also for those who are interested in a deeper read to support group coaching within organisations. I expect Jump! will stay near the top of my working pile of books, becoming increasingly marked up with highlighters & post-it notes a really useful working text!

Its not often that I pick up a book and literally dont want to put it down until Ive savoured every word. This book was one of those, and will undoubtedly appeal to anyone who is interested in the dynamics of Leadership Team performance. The book provides a superb balance between leadership theory and common sense, as well as easily digestible, practical advice on how to facilitate these [Six Game Changing] conversations.
I found the tools and case studies particularly useful. The book even contains fascinating insights from the authors experience of the Kenyan Maasai people and how their collective approach to success has much to teach us in the Boardroom.
JUMP! acts as an important reminder to constantly think about how leadership teams can improve. Its essential reading for even the busiest executive.
