Pia Andrews has long been a powerful voice and a practical exponent of doing government better, not least doing government better in ways which confront and address the difficulties caused by the structures of governments themselves.
This article is a great summary of some of that thinking. Much of its power comes from the recognition that government is fundamentally about people and their relationships with each other, and that that is true as much of people within government as it is of the people that governments serve. Vertical organisational structures can easily be and often are barriers to collaboration and dampeners of motivation, reinforced by a concept of leadership derived from functional management. But none of those is immutable, and a combination of fresh approaches to teams and leadership internally with a readiness to look at the needs of the people governments serve more holistically has real power and potential (greater than either one considered in isolation).
