Root Cause Analysis (RCA) is a method to help identify what, how, and why an event occurred so that steps can be taken to prevent future occurrences. It involves the practices of data collection, root cause identification, and recommendation generation and implementation. In other words, RCA is an application of techniques that allows you to ...

This case study is to identify and evaluate the root cause for failure of a roller press mill. Cement plant has a heavy crushing operation the roller's top surface is eroded, which is replaced by hard metal deposition by welding. In manufacturing, most of the steel metals are failing by either fatigue or by hard deposition through welding.

Root cause analysis (RCA) is the quality management process by which an organization searches for the root of a problem, issue or incident after it occurs. Issues and mishaps are inevitable in any organization, even in the best of circumstances. While it could be tempting to simply address symptoms of the problem as they materialize, addressing ...

In the end, root cause analysis boils down to three goals. The first goal is just as the name implies: to discover the root cause of a problem or event. The second goal is to understand how to fix, compensate for or learn from issues derived from the root cause. The third and most important goal is to apply what you learn from the analysis to ...
