Cause-Effect (Ishikawa, Fishbone) Diagrams

Creates cause-effect diagrams, also referred to as Ishikawa or Fishbone charts. The cause-and-effect diagram provides an efficient summary of factors that impact a process, and hence can be used as a map to guide the overall quality improvement efforts. The cause-and-effect diagram plays a central role in Six Sigma quality programs.
