Didier Cossin
Boards are being asked to govern faster, on harder questions, with less institutional memory than at any point in recent corporate history. Cyber risk, geopolitical exposure, AI deployment, ESG scrutiny and shareholder activism now arrive at the same table, often in the same quarter. Most boards were not designed for this load, and the cost of getting it wrong has moved from reputational to existential.
Didier Cossin helps boards and senior leaders raise the quality of decision-making at the top of the organisation, drawing on the governance methodology he developed at IMD and applied with sovereign wealth funds, supranational bodies and global corporates.
Full Profile
Why organisations work with Didier Cossin
- He is the named author of the Four Pillars of Board Effectiveness, a governance methodology in active use at IMD’s Global Board Center and applied to over 3,000 board members worldwide.
- His advisory client list, which spans the UN, ECB, World Bank, IOC, PIF, ADQ and Temasek, gives him a reference set that very few governance voices can match.
- He treats stewardship as an operating discipline for senior leaders, not a values statement, and has built a body of work, including the book with Stewardship Asia, that codifies what that looks like in practice.
- The second edition of High Performance Boards extends the framework into cyber, ESG metrics, geopolitical risk and board activism, the live agenda for chairs and lead independent directors in 2026.

Biography
The hardest problems a board faces rarely arrive labelled as governance problems. They arrive as a cyber breach, a regulatory letter, an activist shareholder, a geopolitical exposure no one had modelled. The board’s job is to make a decision before the situation forces one. The capacity to do that is what Cossin has spent two decades studying, codifying and teaching.
At IMD, he founded the Global Board Center and developed the Four Pillars of Board Effectiveness, a methodology now used to evaluate and rebuild boards across corporates, sovereign wealth funds and supranational institutions. The framework treats board performance as a function of four interacting variables: the quality and diversity of the people in the room, the information they receive, the structures they operate within, and the dynamics that shape how they argue and decide.
The advisory work tests the framework in unusual settings. He is Senior Advisor in Governance to UNICEF and to the International Organization for Standardization, and has worked with the UN, ECB, World Bank, IFC and IOC alongside sovereign investors including PIF, ADQ and Temasek. The same questions surface across these institutions: how to keep oversight credible as scale and complexity rise, how to protect long-term stewardship when short-term pressure intensifies.
His two books, High Performance Boards (Wiley, second edition 2024) and Inspiring Stewardship (Wiley, 2016), turn that field experience into method. The newer edition adds cyber risk, ESG operating substance, board activism and geopolitical exposure to the original framework, which is now the live agenda for any chair preparing the board calendar for the year ahead.
