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.
