The paper is aimed at presenting main contemporary trends in changing management and the extent of their realization in the practice of Polish public administration. First, an attempt was made to systematize changes in public management (PM) reflected in PM models. The conducted analysis allowed to distinguish a new model, namely the model of innovative public management. It is characterised by high multi-faceted and multilevel capability to solve problems related to management of public affairs. Next, considering basic regularities of contingency approach in management and in implementing organisational changes, and also the necessity of observance of the efficiency principle, it was assumed that innovative management was most useful to the Polish public administration. However, according to quoted empirical research, its implementation is possible in the future because of limited and uneven utilization of the assumptions of this model in practice.
