Feedback: (1)A control chart is a graph of a series of successive observations of a particular step,procedure,or operation taken at regular intervals of time.A control chart contains upper and lower control limits.When such limits are determined statistically,the tool is referred to as a statistical control chart.When successive observations over time are depicted in the chart,it is referred to as a run chart.(2)A Pareto diagram indicates how frequently each type of failure (defect)occurs.The chart is based on the 80-20 rule and as such can be used to identify the most important reasons for a specified quality problem.(3)A cause-and-effect (Ishikawa)diagram also can be used to identify potential causes of failures or defects.These diagrams consist of a spine,ribs,and bones.In general,cause-and-effect diagrams focus on problems related to the following areas: machines,materials,methods,and manpower.For this reason,some refer to the four main categories as 4M.Ultimately,cause-and-effect diagrams attempt to isolate root causes of indicated quality problems.
