Boards can’t solve today’s problems with yesterday’s principles, processes, and attitudes. Too many still rely on outdated governance models that undermine their efforts to create value at a time of accelerating change and proliferating demands. They need a new approach rooted in evidence and tailored to the challenges facing boards today. The engagement theory of governance points the way to a model that fosters insight, agility, and confidence in decision-making. Grounded in research and proven in practice around the world, this approach melds the art and science of governance to drive significant improvements in board performance, whether implemented separately or as part of a broader transformation program.
