Neil Walker gets parachuted in when transformation stalls and escalations multiply. For 30 years, he's recovered enterprise programmes that standard approaches break — not by adding layers, but by building capability that survives leadership transitions. His first book contribution came in 2013 as a selected expert in Gower's Handbook of People in Project Management. Thriving in Turbulence (2025) is the culmination of that trajectory. CIRCA-CLEAR, its diagnostic framework, emerged from a pattern: most transformation failures aren't execution problems — they're misdiagnosis. The wrong intervention applied to correctly observed symptoms. He works where theory meets Monday morning reality. Based in the UK, working globally.
