After a series of successful implementations of management styles in private organizations, the concept of "new public management" officially emerged in the 1980s. Its main objective is to modernize administrative behaviors and management styles and to change the key success factors for both the private and public sectors. On the other hand, the implementation of management styles in public institutions still raises many questions and doubts about their ability to improve public performance. Morocco has recently adopted a turnaround policy aimed at improving public sector performance and management, delivering performance and defining governance styles that meet the needs of Moroccan citizens. This is one of the countries where we are. Today, our administration is faced with a demanding and more critical user with regard to the functioning of public services, it must meet major challenges and cope with demands and complex situations that require discernment, transparency, versatility, communication skills, dialogue and leadership. In this context, it is imperative that the culture of the public administration evolve to fit into the logic of management by performance and by results. Therefore, the objective of this paper is to show the difficulties and challenges of the Moroccan public administration and to propose ways to improve the quality of public services.
