Lisa Woodall
Lisa Woodall is a transformation strategist, enterprise architect, and experience designer who has spent three decades navigating the intersection of people, systems, and change. Her career began not in strategy suites, but on the shop floors of insurance firms and inside briefing rooms at IBM, where the green-and cream striped printouts ran as endlessly as the questions she kept asking: What is this really for? Who does it serve? What could it become?
She has since led large-scale change programmes across financial services, public sector, and creative industries, working with Top 4 consultancies, pioneering offshoring initiatives to India in the early 2000s, and shaping operating models for global transformation. Along the way, she has stayed grounded in one central belief: meaningful change starts when we ask better questions, not just deliver faster answers.
A long-time advocate of bridging strategy and lived experience, Lisa’s work blends theory and practice. She draws on organisational behaviour, systems thinking, service design, and enterprise frameworks like TOGAF, BIZBOK ® Guide, and EDGY, not as academic concepts, but as tools for making real work better.
In July 2020, she began writing blog posts to make sense of the complexity around her. What started as a personal rhythm of reflection during remote working grew into a body of thinking that resonated widely, becoming the foundation for Whatever Next?, a book that invites practitioners to pause, reflect, Reimagine, and rewire how change happens.
Lisa doesn’t just talk about transformation. She’s lived it, on the ground, in the boardroom, and through every tension between old systems and emerging intent. Her work continues to champion a more human, values led, and participative approach to enterprise change.
Gerben Wierda
Gerben Wierda is an accomplished practitioner, speaker and author in the world of Enterprise Architecture. In his own words:
“I am a passioned and experienced (and sometimes even trusted) advisor in the field of all things digital. I write and speak about IT in society, from IT itself, to IT in organisations (enterprise architecture, IT governance) to the way the information revolution affects society. As (occasionally trusted) advisor I try to make sure organisations are capable of making sound design decisions in their ever-changing, ever harder to change and control, IT-heavy business landscapes. Both aspects are executed based on a deep and broad technical insight in IT and the governance/management of IT. I can set up an effective and efficient IT Strategy/Enterprise Architecture/Design Governance setup and build/develop a team for that.
My experience has mostly been (and still is) at the forefront of complex IT landscapes of larger organisations and the use of new methods and technologies in a controlled fashion. I combine a relatively deep insight in technology with the understanding of strategic direction setting and execution. I am comfortable with modern technologies (e.g. Infrastructure as Code, Cloud, API-landscapes, AI) and methodologies (Agile, DevOps) and have a decent feel for IT Security.
As a person I am also interested in psychology, biology, physics, mathematics, history, philosophy & language, as well as in making sure the world is a fair and healthy place.”
Gerben’s books include Mastering ArchiMate and Chess and the Art of Enterprise Architecture.
