In order to succeed in today’s fast-moving business environment, we need to "build our organisations into engines of possibility". This relies on attaining high levels of alignment AND autonomy so that everybody in the organisation knows what they need to achieve and why, is free to decide how best to do it, and genuinely cares that it gets done. I call this "the agility challenge". Rising to this challenge requires a new type of leadership characterised by 4 Cs: Curiosity, Clarity, Courage and Care. In this talk, I explore leadership values and practices essential for the agile enterprise.
