Practicing what he preaches, except he doesn't preach -- he doesn't sell, huh?
John help teams, managers, leaders, change agents, and execs. He can answer all sorts of up to date questions with ease. John coaches, teaches, consults for sustainable growth of agility in non-software as well as software. He created Broad and Deep agility (BaDa) on top of the shoulders of existing theory & practice. See https://www.youtube.com/watch?v=fUen2CeyTDk. John himself is broad & deep from the points of view of agility, people & change.
Standing on the shoulders of giants
John is a systems thinker who happens to be a huge fan of Cynefin and sees the benefits of both, erring on the side of Cynefin where they clash. Most importantly, John takes an independent view. John is also a people & change thinker; he uses Spiral Dynamics Integral (certified to level 2) and other models; even if they are criticized in some quarters as pseudoscience, John finds aspects of Spiral Dynamics helpful in structuring better conversations with people.
More proof he knows what he's talking about, and has done what he talks about
John is grateful to be part of Marshall Goldsmith's #payitforward campaign and, in so doing, offers free coaching/mentoring/co-training to a selection of potential agility chefs. John is a member of the #MarshallGoldsmithLead60 group, a cohort from the 16,000+ #MarshallGoldsmith100CoachesApplicants. It was a privilege for John to be one of a lucky group of 60 people; Marshall Goldsmith himself taught that group in Salt Lake City in February 2018. All of John's workshops #payitforward Marshall Goldsmith content, including Marshall's advice to John himself.
John typically practiced with many of his clients for 18+ months. He is switching to shorter-term engagements. John's client list (directly or indirectly) includes Shell, BP, Barclaycard, Lloyds Banking Group, Vocalink Mastercard, MBB consulting firms, Centrica / British Gas, the Musgrave Group, RR Donnelley, DELL, Nordic Aviation Services, 84.51, Intralinks, PaySafe, and Ericsson.
