How can you design a value stream for lean production from scratch?

3 Design your future state

A future state map is a visual representation of how you want your value stream to operate in the future. It shows the improvements and changes you plan to implement to eliminate waste and increase value for customers. To design your future state, you need to apply the lean principles and tools, such as pull systems, kanban, kaizen, 5S, or cellular manufacturing, to your current state map. You can use tools such as value stream design symbols, takt time calculations, or flow diagrams to help you draw your future state map. The goal is to create a smooth and continuous flow of value from supplier to customer.

4 Implement your action plan

An action plan is a detailed list of tasks, responsibilities, resources, and timelines that you need to execute to achieve your future state. To implement your action plan, you need to prioritize your improvement projects, assign roles and responsibilities, allocate resources and budget, and monitor and measure your progress and results. You can use tools such as Gantt charts, PDCA cycles, or A3 reports to help you manage your action plan. The goal is to sustain and improve your value stream performance and customer satisfaction.

5 Review and revise your value stream

A value stream is not a static entity, but a dynamic and evolving system that responds to changes in customer demand, market conditions, and production capabilities. To review and revise your value stream, you need to continuously collect feedback, data, and insights from your customers, suppliers, and employees. You can use tools such as gemba walks, customer surveys, or performance dashboards to help you evaluate your value stream performance and identify new opportunities for improvement. The goal is to keep your value stream aligned with your customer needs and your business goals.
