Modélisation et Réorganisation des Processus dans le Cadre de l'Externalisation

Abstract : The industry environment has changed in the past decades becoming more complex and unforeseeable than ever. New information and communication technologies and new relationships within and between organisations favoured cultural and socio-economic changes so that interdependency of company services and functions has become evident.
The company today faces multiple issues such as faster product cycle times and new industrial and environmental constraints.
Those issues result in the redefinition of performance structures of the company. On one hand, on an organizational level, this redefinition consists in the process redesign (Business Process Reengineering, BPR) that helps taking into account the integration of the company activities, which were strongly compartmentalized before their reorganization. On the other hand, it consists in the refocusing of the company on its core competencies by transferring company activities or functions, which are considered as not strategic, to external partners.

Our research work is situated within this context. In this PhD, we study the problem of process modeling and redesign in the context of the logistics reorganization of the industrial Group Rhodia. Our objective is to examine how to attain an optimized transverse company management (internal aspects), to redefine the company processes in the context of outsourcing of certain process parts (focus on core competencies), and finally to integrate an interdependent and multi-actor process organization (partner relationships).
Within this perspective, our research aims at bringing about methodological tools and configuration practices for supply chain management by particularly concentrating on supply chain processes as well as the links between the activities and actors that conduct those processes.
Our will concerning this research work on an industrial ground is to demonstrate the importance of process organization within the supply chain as well as to present the concepts and approaches, which evolve around process modeling in order to propose, in fine, an outsourcing methodology that is supported by process modeling and reorganization.

Thus, the first chapter of our PhD lays the framework of our research: the supply chain organization and the importance of processes within this one.
The growing global complexity of the company's industrial environment has changed the mechanisms and organization principles. The company engages in an improvement of its way of working, internally within its organization and externally with its direct partners.
The concept of supply chain management is clearly associated to this evolution because it is greatly based on process reorganization of the company for which the major stakes consist in a transverse organization in order to attain global supply chain improvement and not locally optimized silos.
The first chapter also allows us to present the problematic we address in our research work: the supply chain organization in the context of outsourcing. Therefore, we introduce the industrial background of our work (restructuring of the organization we consider) as well as the industry sector and the related issues (outsourcing objectives in the sector of specialty chemicals). The Group Rhodia faces major stakes of cost reduction and wants to refocus on its core competencies, the specialty chemicals, through the outsourcing of those parts of its logistics, which the Group considers as not being part of its core organization. Rhodia thus aims, through activity reorganization and process outsourcing, at simplifying and lightening its organization in order to be more productive and to keep and attain new competitive advantage in its four main industries: pharmaceuticals and agricultural chemistry, food and consumer goods, industry and services, automotive, and electronics, and fibers.
This chapter allows us to lay and present the basis for our reflection of defining and carrying out the outsourcing process.

In order to reach this objective, we concentrate in the second chapter on the concepts and approaches, which are associated to process modeling and reorganization. First we determine the general articulation of the approach we propose and we present a certain number of models, methods, tools, etc. enabling internal process reorganization and accompanying the outsourcing of activities to external service providers.
We notice that process reorganization is a relatively new concept, which is particularly being considered in industry during the last decade. The research work around this subject and the methodologies, techniques, etc., used in the industry, points out that in comparison to the “organizational” aspects, there is a predominance for the “technical” point of view in that matter.
It is the organizational aspects we consider in our research work in order to extend the application of BPR in the context of outsourcing and the sharing of logistics activities of the partners. We use for our work an international process standard of the supply chain, the SCOR-model, which was chosen by the Group Rhodia for the management of its main management processes.
This chapter allows us to develop a structuring methodology including three steps (“as is” – “to be” – “go live”) and to employ this one in the case of outsourcing.

The third chapter allows us to apply our research work on an industrial level. Through different case studies, led within the Group Rhodia, we illustrate the importance of an integrated and standardized vision and the activity interdependency for the process reorganization applied to logistics outsourcing.
We propose a three stage development: the process modeling, analysis and reorganization, helping to make evolve the company on an internal level, allowing the activity outsourcing (in our case a part of the logistics process), and finally improving multi actor functioning of the supply chain.
In order to define a consistent process that is under control, it is necessary, before outsourcing whatever company activity, to have a global vision of the tasks that are to be executed in order to identify those, which are likely to be outsourced, and those, which need to be hold internally. Moreover, for a successful outsourcing process, it is essential to integrate in this one the external service provider as a strategic partner of this reorganization effort. Hence, one also needs to consider the interdependency between all activities so as to respect the global process and thus the supply chain.
The third chapter thus allows us to propose a process modeling approach in the context of outsourcing in the following way:
¬ “Why to outsource” – decision making for outsourcing
¬ “What to outsource” – activity identification for the outsourcing effort
¬ “How to outsource” – BPR with the help of the SCOR-model and “traditional” BPR methodology for the processes, which are not in the scope of the SCOR-model
Thus based on the results of our industrial case studies, we establish in this chapter an approach for process reorganization and outsourcing within the context of Rhodia's supply chain and define an outsourcing plan through process reorganization.

Finally, we conclude this PhD by turning back on the academic and industrial contributions of this manuscript concerning process reorganization of the company in the context of outsourcing. We present at last a certain number of research perspectives in this area
