In project selection, what method does Lean often use?

Value stream mapping is a pivotal tool used in Lean project selection because it visually represents the flow of materials and information in a process. This method helps identify value-added and non-value-added activities, enabling teams to pinpoint areas for improvement. By mapping out the current state of a process, organizations can better understand where waste occurs and how to streamline operations effectively.

This visual process not only aids in recognizing inefficiencies but also assists in prioritizing projects that can deliver the most significant impact on efficiency and effectiveness. It allows teams to make informed decisions based on concrete data about where interventions should occur to enhance performance and reduce waste.

While other methods like statistical process control or benchmarking are useful in their own rights, they do not focus on the identification and elimination of waste in the same way value stream mapping does. Random sampling, while a vital technique in data collection, does not facilitate the targeted project selection that Lean methodologies promote. Therefore, value stream mapping stands out as the most appropriate method in the context of Lean for selecting and prioritizing improvement projects.
