About the Author – Markus Sullivan


Grounded in practice. Shaped by failure. Proven in delivery.

I’ve spent my career helping organisations deliver change that actually lands. Not just projects that finish – but initiatives that transform how people work, how technology enables them, and how the business measures success.

Across financial services, telecoms, and regulated industries, I’ve led major change and IT programmes ranging from multi-million-pound regulatory implementations and system migrations to global cybersecurity transformations. Along the way, I’ve learned that successful delivery isn’t just about frameworks – it’s about clarity, culture, and accountability.

My background combines hands-on programme management with strategic portfolio leadership. I’ve built and coached delivery communities, rescued failing initiatives, and designed PMO frameworks that move organisations from reactive firefighting to proactive, data-driven control. Whether shaping FCA-compliance portfolios at Aviva, developing the APM Body of Knowledge, or guiding The Cumberland Building Society through proposition simplification ahead of a core banking migration – my focus has always been the same: turn complexity into confidence.

I’m a Chartered IT Professional and Fellow of the British Computer Society, holding a BSc in Business IT Project Management and a Diploma in Artificial Intelligence from the University of Oxford’s Saïd Business School. But more importantly, I bring perspective – having seen what good delivery looks like, and what happens when it goes wrong.

Today, I work independently with organisations seeking to raise their delivery maturity, strengthen PMO capability, and align projects with measurable business outcomes. I help senior leaders ask the right questions, PMOs design frameworks that fit, and teams rediscover the satisfaction of delivering work that truly matters.

Because in the end, project management isn’t bureaucracy – it’s how strategy becomes reality.
