What is Root Cause Analysis (RCA)?

RCA is a process to help you identify causes and preventive actions. For example, if a chemical spill occurs, you would attempt to identify the root cause of the spill occurring so that you could address the cause and therefore prevent a spill from occurring in the future.

RCA can be used to describe a formal analysis process, however, it also can mean something simpler, looking past the obvious or immediate reason for a nonconformance and therefore being able to determine why the nonconformance occurred. This analysis can be done by either an individual or a group, with one person in charge of recording the ideas produced.

The root cause diagram will help you organize your thoughts when you analyze your facility’s potential for environmental impact. This analysis can be done by one person or by a group, with one person writing down the ideas produced. Each diagonal line represents a main component of the production process. Each horizontal line stemming from the diagonal represents an important element contributing to the labor component. This diagram is a device to help organize the analysis of the cause of potential environmental impacts. Use it if it helps, but don’t get hung up on trying to make it work.
