What element is NOT part of a value stream map?

The element that is not part of a value stream map is the profit margin. A value stream map is a visual tool used in Lean methodology to analyze and design the flow of materials and information required to bring a product or service to the customer. It typically includes elements such as Kaizen bursts, which indicate opportunities for improvement, push arrows that represent the flow of materials or information, and inventory levels at different points in the process.

Profit margin, however, is a financial metric that focuses on the profitability of a product or service. While it is important for overall business performance and decision-making, it does not directly depict the operational aspects involved in the process flow and value creation, which are the primary focus of a value stream map. Thus, including profit margin would not align with the purpose of mapping value streams and identifying areas for waste reduction and efficiency improvement.
