Relire les lois du service public, c’est (re)mettre en question le socle des trois principes — égalité, continuité, adaptation constante — solidement établis et largement connus, depuis environ un siècle, comme structurant le régime juridique spécifique de l’ensemble des services publics ; c’est interroger l’actualité de ces principes généraux dans un contexte profondément renouvelé et, à travers elle, la pérennité du service public lui-même, en tant qu’objet juridique. Afin de dresser pareil bilan de santé, deux niveaux de relecture sont retenus. Il s’agit, en premier lieu, de revenir sur l’ensemble théorique que constituent aujourd’hui les lois d’égalité, de continuité et d’adaptation constante : ces dernières, devenues subsidiaires par rapport aux impératifs économique et gestionnaire, ne semblent plus être des données de premier ordre dans le système de pensée juridique des services publics ; elles continuent toutefois d’assurer l’unité de la notion de service public, notion réduite à la portion congrue. Il s’agit, en deuxième lieu, de reconsidérer chacune des lois séparément, dans son contenu : la signification respective des trois principes classiques a évolué et de « nouveaux principes » sont recherchés, ceux-ci n’étant pour l’essentiel que des déclinaisons plus ou moins nouvelles de ceux-là ; une tendance à leur subjectivisation est observable sans devoir être exagérée, les lois du service public continuant d’exprimer l’esprit objectiviste du service public. / Reviewing the laws of public service means questioning the foundation of the three principles — equality, continuity, mutability — that have been firmly rooted and widely known, for about a century, as structuring the specific legal regime of all public services. It also means questioning the developments of these general principles in a profoundly renewed context and, through it, the durability of the public service itself, as a legal object. To do so, two review levels are employed. On the one hand, we have to go back over the theoretical set of the laws of equality, continuity and mutability, which have become subsidiary to economic and managerial imperatives and as such no longer seem to be the most important considerations in the legal thought system of public services. However, they continue to ensure the unity of the notion of public service, a notion reduced to its bare bones. On the other hand, we have to reconsider each of the laws separately, in their content. The respective meanings of the three principles have changed and « new principles » are being sought, these being essentially newer variations of those. A tendency to give more consideration to the individuals involved when applying the laws can be observed but must not be exaggerated, as the laws of public service are continuing to express the objectivist spirit of the public service.

Business process reengineering (BPR) was analyzed as one of the approaches to considerably improve the performance of the enterprise. The actuality of BPR in times of economic downturn was evaluated. The historic evolution of the concept was examined and findings about the economic nature of BPR emergence were made. The dependence of BPR actuality and simplicity of BPR usage on the level of enterprise business process maturity was shown. A conclusion about optimal point was made via depicting the interrelations graphically. Advantages of BPR usage for enterprises of different sizes were proved and specified. Benefits of BPR were compared with benefits of other related methods like ERP, JIT, TQM and Continuous Improvement. The future possible development of the BPR was analyzed. There offered possible further directions of research in the area of BPR based on current limitations of the concept. Results of the research may be used in companies of maturity level one to three, taking into account size of the company and current state of business process maturity.
