“Jack is an innovation consultant who walks the talk. He is constantly innovating his own business activity, its design and aims.
He is ‘the person’ to talk to for large group interventions, for whole system change and innovation. I attended a four-day Open Space conference that Jack facilitated. It set me on a new path in life.
Jack is highly committed and skilled, challenging and truly creative. He thinks deeply about innovation and transformation. He has developed a range of propositions about innovation that can lead to new insights on the topic. He understands creativity and innovation and has developed practical ways to develop innovativeness in organisations.
Jack’s views tap into the wild and the wonderful as well as the rational. He likes to shake things up, and to help that shaking to happen quickly. He doesn’t mess about!
You won’t always find it easy working with Jack because he is one of that rare breed — an authentic agent of change and innovation who is prepared for things to get harder before they get easier.”

“For three decades Jack has been the go-to walking encyclopaedia of the very best and most innovative management and organization theory. He is second to none in comparing, contrasting, and critiquing models, explaining complex management thinking simply and memorably, and turning ideas into effective practice. A sophisticated thinker of this calibre and breadth of knowledge who is also a skilled practitioner, is these days something of a rarity.”

“Jack is a practical sorcerer. He is always gathering new substances, forces and ingredients to cast ever more effective spells that create innovation magic.
Jack is a person I am proud to know for his willingness to regularly recast himself and the world around him, always aimed at the authentic new. Newness often involves the painful process of shedding old skins, but Jack walks his talk and redrafts himself with the passion and artistry of the great painters and sculptors.
Jack is an exemplar of collaboration, taking us from now to new, on expeditions that can take a day, and yet can have all the richness and excitement, learning and challenge of a safari through personal and organisational jungles.
Jack’s a world pioneer of Open Space 2.0 and beyond, a man who lives for a living, there’s nothing facile about his facilitation, a prolific maker-upper of ideas and approaches, processes and methods that help create futures in the now.
I’ve worked with and dialogued with Jack for many centuries; he’s inspiring, a sharer and, most of all, an innovation Samurai.”
