Governance is all about decision-making and there may be no better metaphor for operational governance in action than a tennis umpire.
Umpires and line judges make decisions in real time about the rules of tennis, and actively work to mitigate the risk of these decisions impacting on play. Umpires also provide assurance to players, spectators, sponsors, and the public that the game will be played within the rules.
Anyone watching the 2019 Australian Open tennis would have noticed some great split second decision making by umpires and line judges in high pressure situations involving balls travelling at hundreds of kilometres per hour.
