A cause-and-effect diagram (also known as a fishbone or Ishikawa diagram) is a useful tool to help identify the different factors that could be contributing to the quality issues with the taillight assemblies. It allows management to visualize the possible causes of the problem and to focus on specific areas for improvement. Histograms and scatterplots are tools used for analyzing data, and the given data does not provide enough information for their use. Plan-Do-Check-Act is a cycle for continuous improvement and does not directly address the issue of identifying the causes of the quality issue.
