Which basic tool of quality is used to analyze process flows and identify issues?

Process mapping is an essential tool in quality management that helps in visualizing and analyzing the flow of processes. By creating a detailed representation of the steps involved in a process, process mapping allows teams to see how each step connects to others and identify where inefficiencies, bottlenecks, or non-conformances may occur.

This technique not only highlights the sequence of activities but also provides insights into inputs, outputs, and interactions between different parts of the process. In doing so, it aids in pinpointing specific areas that require improvement or intervention, making it easier to address quality issues effectively.

While other tools mentioned, such as control charts and causal diagrams, are useful in their own right, they serve different purposes. Control charts are primarily used for monitoring process variability over time; causal diagrams are designed to show relationships between various factors affecting a process and identify root causes of problems; scatter charts are used to identify correlations between two variables. Each of these tools has its unique focus, whereas process mapping serves as a foundational tool for understanding and improving the overall flow of processes in a more comprehensive manner.
