In a highly competitive environment, cost reduction and optimization of the supply chain are more than ever a strategic issue for companies. In this work, we are going to propose and analyze a model of design and development of the Lean Supply Chain strategy. This model based on the results and the logic of the model proposed in the previous research work, and more precisely the way of the determination of Supply Chain strategies, whose aspect is operational excellence. This model serves as a decision support tool for business managers to design or develop Supply Chain strategies based on the Lean supply chain.

In a highly competitive environment, cost reduction and optimization of the supply chain are more than ever a strategic issue for companies. In this sense, lean manufacturing is a lever that allows the company to continuously reduce the time required for the transformation of raw materials into finished products, eliminating waste and with the aim to meet the growing and diverse needs of these customers. In this paper, it based on the latest studies in this field in order to highlight the relationship between supply chain and lean manufacturing at reducing costs, eliminating waste and non-value added. Then it highlights the impact of lean manufacturing on the reactivity of the supply chain through inventory reduction, cycle time and flow acceleration. Finally, it presents the role and expectations of the supplier in the context of the merger Lean Manufacturing and Supply Chain. This research has enabled to understand the impact of lean manufacturing concepts on supply chain strategies.

In a highly competitive environment, cost reduction and optimization of the supply chain are more than ever a strategic issue for companies. In this context, the good alignment of the supply chain with the corporate strategy is essential to ensure a high level of performance. The design or the choice of a Supply Chain strategy is determined at the same time by the objectives of the company, but also by the taking into consideration of the environment where the supply chain is inserted. Then, according to the specifications and the request of the customers, the strategies converse between the operational excellence or the customer closeness. This research serves as a model or a theoretical framework supported by experiments through surveys in companies of the United States and Canada for the design of Supply Chain strategies aligned with the strategy of the company.
