Histograms are used to present the data is in order to make it easier to understand the the data for subsequent analysis. Then the identification of the types of defects are dominant using pareto diagram. The next step is to look for factors that cause damage to the product using a causal diagram can then be prepared for a recommendation or a proposal of quality improvement.
