. Research shows that a wind turbine is around 30-45% efficient increasing to 50% during peak wind times. If wind turbines were to be 100% efficient, the wind would completely drop after going through the turbine. Assume that the efficiency of the Star of the South is 20%. . Please provide a reference also. (fishbone or Ishikawa diagram) to identify why this maybe the case. b) Explain how the diagram can be used to identify possible relevant issues and how this might be used as part of a project to improve the efficiency of wind turbines. c) What are the areas of inquiry that the leadership team needs to evaluate to develop a deeper understanding of problem-solving?
