The check sheet is a form (document) used to collect data in real time at the location where the data is generated. The data it captures can be quantitative or qualitative. When the information is quantitative, the check sheet is sometimes called a tally sheet. The check sheet is one of the so-called Seven Basic Tools of Quality Control.
Run chart will indicate special cause existence by way of Trend , osciallation, mixture and cluster (indicated by p value) in the data.Once run chart confirms process stability ,control charts may be leveraged to spot random cause variations and take necessary control measures.
The Pareto diagram is then used to determine the major reason for delivery problems. Then, the process of tunneling down into the process begins. This is done by taking the highest bar on the Pareto diagram and collecting data on what causes that problem to occur - again both in Pareto and control chart form.
The scatter diagram is known by many names, such as scatter plot, scatter graph, and correlation chart. This diagram is drawn with two variables, usually the first variable is independent and the second variable is dependent on the first variable.
