The document discusses the fish bone technique, also known as the cause and effect diagram or root cause analysis. It was invented in 1943 by Dr. Kauro Ishikawa to help identify potential causes for quality problems. The technique involves constructing a diagram that resembles a fish skeleton with main categories and sub-categories of causes. The steps include defining the problem, brainstorming potential causes, and identifying the root cause. An example case study on identifying the root cause for a drop in sales is provided. The fish bone technique is best for complicated problems with many potential causes and a large team, while it may not be suitable for simple problems or those with communication issues.
