TOPIC: Root cause analysis vs cause effect diagram

hello
what is the difference between root cause analysis and cause effect diagram ?? i'm little confused because the two have the same objective!!

Hamza:

Root cause analysis is a process. There are a number of RCA techniques, such as 5-Whys, Fault-tree analysis, failure modes and effects analysis. A cause-effect diagram is a way to map or display the results of a root cause analysis. Examples include a BowTie diagram, Fishbone (or Ishikawa diagram) or display called "causal mapping."

They both have the same end point in that they are trying to find the root cause for a failure. One is a process or technique, the other is a display of the process or the results of the process.

Hope that helps
