This paper explains that quality control
procedures are particularly useful in business, when properly deployed, because they can help managers to transform incomprehensibly varied or difficult
data into more understandable
information. The author states that
histograms, which depict the number or
proportion of data points falling into any particular given class, can be easily understood by the naked eye of laypeople, but they also can be manipulated very easily to yield false impressions because of their seductively seamless appearance. The paper points out that the check sheet is a data-
gathering and interpretation tool used for distinguishing between fact and opinion, gathering data about how often a problem is
occurring and gathering data about the type of problem occurring. Table of Contents Issues and Organizational Examples Histograms Cause and Effect Diagrams Check Sheets Summary and Conclusion
