Valle, Matthew creator text xu| 2001 continuing ng p.45-58 This paper argues that the changing nature of public service requires new leadership and that the Primary goal of leaders in public organisations today should be the development of, as the organisation's primary core competence, an adaptive organisational culture. The changing nature of public service will be discussed in terms of the external and internal environmental forces impacting public organisations, the expanded and diverse missions that make up the work of the members of these organisations,s and the style of leadership appropriate in order to take steps to create the organisational energy necessary for action. The model presented emphasizes the interaction of the environment, the followers, and the leader and describes this interaction as a combination of crisis, culture, and charisma. - Reproduced Public administration Culture Leadership Management in Government 180718
