Using Lean thinking, we should be managingthe value stream. Lean thinking focuses on optimizing the entire flow of value from the initial customer request to the delivery of the final product or service. Managing the value stream involves identifying and eliminating waste, reducing delays, and ensuring smooth flow across all steps in the process to deliver maximum value to the customer. Lean emphasizes managing the process flow rather than micromanaging individual steps or people, allowing for continuous improvement and more efficient operations.
