The Bank does not claim more accurate foresight than other analysts, but it can educate, inform, and explain its own decision-making approach, and thereby minimise one potential source of uncertainty. It can help make more predictable what would otherwise be less so. Doing so also provides important benefits for the Bank.
Another book on leadership emphasises that good leaders are those that teach others to lead themselves. At the end of it all, the team itself says that they did it themselves. I am a firm believer of this principle.
