Tools for Identifying Problems consists of Histogram and Statistical process control chart. Check Sheet is an organized method of recording data. Scatter Diagram is a graph of the value of one variable vs. another variable. Cause and Effect Diagram is a tool that identifies process elements (causes) that might effect an outcome. Pareto Charts is a graph to identify and plot problems or defects in descending order of frequency. Flow Charts (Process Diagrams) is a chart that describes the steps in a process.
Histogram is a distribution showing the frequency of occurrence of a variable. Statistical Process Control Chart is a chart with time on the horizontal axis to plot values of a statistic.
