The manual is divided into three parts, which take into consideration in the first part the theories and concepts of the world of organisations, in the second part the policies and tools, and at last, in the third part two paradigmatic case studies, in which we examine, on the one hand, the role of public policies tested in Italy and in various OECD and European Union countries, according to the various attempts to reform and modernise public administration. On the other hand, in the era of globalisation and flexible capitalism, a strategic reflection on the evolution of entrepreneurial culture and the transformation of corporate organisational models is proposed. A challenge connected with the recognition by management of a growing corporate responsibility not only towards shareholders but towards all stakeholders correlated with a significant diffusion of a particular type of company, called integral company.
