SupplyChainBrain recently published an article outlining a four-step methodology for creating leaner and more effective supply chains. This methodology is composed of four steps: understanding the supply chain, identifying the areas of improvement, creating a plan of action, and implementing the plan. The article explains that understanding the supply chain is the first step, as it allows companies to identify areas of improvement and develop a plan of action. The second step is to identify the areas of improvement, which can be done through data analysis and customer feedback. The third step is to create a plan of action, which should include a timeline, budget, and resources. Finally, the fourth step is to implement the plan, which should be done in a timely and efficient manner.
