Explanation
A fishbone diagram (also called an Ishikawa or cause-and-effect diagram) is specifically designed to identify root causes of a problem by visually mapping categories of potential causes (people, process, equipment, materials, environment, etc.) leading to the observed effect. Since the analysis concluded there was a 'design error' - a root cause - the fishbone diagram is the most fitting tool. A histogram shows frequency distribution; a Pareto chart identifies the most significant problems by frequency; a scatter diagram shows correlations between two variables. Only the fishbone diagram is structured for root cause analysis.
