Being considered effective and creating value for national economies for many yeras, public organizations have sought in recent years to restructure and perform better. A questioning seems to characterize them given ther dysfunction followed by their poor performance. Obviously, the basic assumptions of administive action as well as traditionnal instruments appear insufficient and obsolete. Faced with this situation, a new perception of public management, in this case NPM, there fore becomes essential to meet the needs at the hour.
The objective of this paper aims to explain the articulation of the New Public Management concept in public organizations. Although in Chad, the implementation of this new management style has been significantly delayed, organizations using this concept are campaining for performance. To the extent that they have managed to reduce organizational dysfuction, NPM becomes an absolute necessity for all organizations, in order to achieve the desired performance.
