Percy Mansfield

Enterprise transformation and change leader who takes ambiguous, high-stakes initiatives from concept to durable adoption. I lead the strategic change that carries a sponsor's vision to the front line and makes it stick, bring the execution and process improvement discipline of a Master Black Belt with $500M+ in enterprise impact, and put AI to work where it earns its place. An owner-minded orchestrator who aligns People, Process, and Technology and has coached 1,000+ employees.

Associate Director, Business Process Optimization at Markel Corporation (2022-01 – Present)

Own high-priority, often ambiguous transformation initiatives, taking each from leadership concept through execution and adoption across a 400-person Global Finance organization.

• Finance of the Future Transformation — led execution on cross-functional initiatives within a CFO-sponsored, five-pillar transformation, driving them from idea to completion and aligning People, Process, and Technology at each step.
• Led cross-functional project teams implementing new processes and technology, through to full adoption.
• Facilitated regular Hot-House and strategic-planning sessions to bring teams together, improve collaboration, and keep leadership focused on the long-term roadmap.
• Finance Talent Team — led a standing committee of 10-15 volunteers for 5+ years, with representation from every department and location, chartered to raise capability across the 400-person Global Finance organization — a leadership role taken on in addition to core responsibilities.
• Built and ran the full program: monthly 'Stop-Drop-and-Learn' sessions, newsletter articles on personal-development, curated learning resources, and major CPE events, with attendance tracking, needs surveys, and quarterly progress readouts to leadership.
• Partnered with HR to drive adoption of online learning ('Markel University' via Skillsoft & LinkedIn Learning) and presented learning opportunities to the full Finance org at quarterly all-hands meetings.
• AI Enablement & Adoption — served as a lead tester and early adopter in the company's Tech Champion Network, piloting Microsoft 365 and Copilot across the Finance org and coaching teams to adopt AI as a daily thought partner.
• Scoped AI use cases and led business requirements that feed the technical team's build of production agents — orchestrating the solution rather than writing the code.
• Compressed one leadership-development program's build time from weeks to under a day using Copilot, teaching both the concept and the underlying AI skills.
• Maintained hands-on fluency in Copilot Studio, Power Platform, and Alteryx — enough to prototype solutions and give technical teams precise direction.

Change Management Lead — Oracle Fusion, Guidewire BillingCenter, Project Phoenix at Markel Corporation (2017-01 – 2022-12)

Dedicated change leader across three enterprise transformation programs, owning change management and communications.

• Owned the full change lifecycle on major global software implementations — from project onset through go-live and into sustained adoption — ensuring program goals were realized through user proficiency, not just technical delivery.
• Led change and adoption for the Oracle Fusion implementation: the daily system for a 400-person Global Finance team, with invoice-approval and expense-reimbursement workflows reaching all 5,000+ employees and supplier base.
• Drove change for the Guidewire BillingCenter rollout across a 50+ person billing team, managing downstream impact to every internal group interfacing with policies and to thousands of customers.
• Established and led networks of Change Agents to carry end users through each transition, and managed consultant teams to build training curriculum and enterprise communications for both employees and leadership.
• Built repeatable change capability that let involvement ramp down across successive phases of Project Phoenix — enabling the move into the Associate Director role while change continued to land.

• Partnered with departmental leadership to identify and prioritize the highest-value project opportunities.

Emergency Storm Operations — Site Leader at Dominion Resources (2008-01 – 2013-12)

• Owned the full logistics chain under acute pressure — badging, mapping, lodging, feeding, materials staging, and dispatch — coordinating inbound crews with storm operations centers to get workers where power needed restoring.

Manager, Operational Excellence at Earth Tech Inc., A Tyco International Company (2006-01 – 2008-12)

• Built the Six Sigma talent pipeline within the shared-services center and stood up a Strategic Sourcing analyst team from the ground up, together delivering $11M+ in savings.
