Change Manager delivering ITIL-aligned change governance to protect critical services and enable transformation.
United KingdomWhat I'm looking for
I’m a results-driven Change Manager with 15+ years delivering end-to-end change governance across critical infrastructure, construction, and professional services environments. I’m certified in Digital Change Management (CDCMP) and ITIL 4, and I focus on consistently protecting service stability while enabling business and technology transformation.
Across multi-site operations, I own the full change lifecycle—from change risk assessment and impact analysis to post-implementation review (PIR). I chair Change Advisory Board (CAB) sessions, manage the Forward Schedule of Change, and enforce ITIL-aligned governance to prevent unplanned outages caused by poorly controlled changes.
I build change visibility and performance reporting for leadership, tracking change success rates, failed changes, and emergency change volumes to drive continuous improvement. In technology transition programmes, I also maintain CMDB accuracy so CAB decision-making is grounded in reliable configuration data.
I bring strong stakeholder engagement and multilingual, international experience (UK, Spain, Eastern Europe). I also lead and mentor teams, strengthening service desk and knowledge management practices through structured governance, SLA monitoring, and continuous service improvement.
