Apports de la gestion industrielle au management des périmètres irrigués : comment mieux piloter la production ?

Abstract : Improving the performance of irrigation systems by promoting better management is a fashionable subject. Unfortunately, the definitions of "performance" and "management" are among the most controversial in the irrigation community. This failure to grasp the true meaning of such crucial terms has often led to misunderstandings and confusion. This thesis intends to bring the debates to a more neutral and raisonably well understood territory : the field of industrial production systems. The underlying hypothesis of this approach is that the terms of an analogy between the "production process" of water in an irrigation system and a standard industrial process can be made more precise and this should allow irrigation managers to derive lessons from the methods used in industry. Moreover, the specific objective of this thesis is to define the basics of a method of intervention for analysis and improvement of water management performance in irrigation systems inspired by the experiences and concepts of industrial management.
The main terms of the analogy are initially discussed : boundaries of production systems, product, production process and management methods. While recognizing that production processes in irrigation present some strong specificities, it is then proposed to adopt the perspective of most interventions in industry and to work on a representation of the management system supporting the production of water. The principal features of this representation are discussed at some length ; one distinguishes clearly three levels of management : (1) Seasonal allocation of ressources, (2) Water issues scheduling, (3) Operation of hydraulic structures, and two main types of coordination between the managers of these different levels : (1) Hierarchical coordination from the first level downwards and (2) Nonhierarchical coordination between managers of a same level looking after a particular production process. It is then mentioned that classical methods used for analysing and designing information systems can be mobilized for clarifying the activities of the different managers within the framework provided by the representation.
The use of the previous representation of the management system is finally put into perspective within the three stages of a method of intervention. Since the performance of a production system can only be judged by relating objectives and outputs of its production processes, it is considered as natural to use a representation emphisizing and clarifying these processes to perform a diagnosis. It is argued that the weaknesses of the management system detected through the analysis of the represention are in fact, explicit symptoms of the dysfonctionality of the production system with regard to the objectives. This assertion can greatly facilitate the diagnostic phase of an intervention and permits to focus thereafter the involvement of experts (mainly technical, managerial and institutional fields) whose role will be to find out the true causes underlying these weaknesses and to propose actions for curing them.
The experience accumulated through consulting in industry tends to validate the three stages proposed as an approach for intervening on a production system : representation, symptoms of dysfonctionality, cause of dysfonctionality. This approach can only be put in practice if the different managers of the system considered are involved from the beginning in the process of defining, understanding and criticizing a global and shared representation of their management system ; in that sense, this approach is indeed very close to the concept of reengineering recently popularized by management consultants in industry.
