Using a process map to identify waste or non-value-added activities is highly effective because it visually represents the workflow of a process. By mapping out each step, stakeholders can clearly see how tasks are interconnected and where inefficiencies may lie. Process maps often highlight stages that do not add value to the end product or service, making it easier to identify bottlenecks, redundancies, and areas for improvement.

In contrast, force field analysis, while useful for understanding the dynamics of change, does not primarily focus on mapping processes or identifying specific waste. Pareto analysis identifies the most significant factors contributing to a problem, often directing attention to the "vital few," but it doesn’t provide insights specifically related to the workflow itself. The scatter diagram is beneficial for examining relationships between two variables, but it doesn’t visualize processes or activities directly. Therefore, the process map stands out as the most effective tool for pinpointing areas of waste.
