Basic tools of quality

1. Control Chart

   • The control charts are used to analyze the behavior of different processes and to be able to predict possible production failures using statistical methods. They are used in most industrial processes.

2. Ishikawa diagram

   • It is a diagram that due to its structure has also come to be called: Fishbone diagram. It consists of a simple graphic representation that has the shape of the spines of a fish horizontally, representing the problem to be analyzed, which is written to its right and to its left the causes that originate it.

3. Pareto Chart

   • It is a graph to organize data so that they are in descending order, from left to right and separated by bars. Allows you to assign an order of priorities. The diagram allows to show graphically the Pareto principle, that is, that there are many unimportant problems compared to a few very important ones.

4. Histograms

   • It is a graphical representation of a variable in the form of bars, where the surface of each bar is proportional to the frequency of the values represented. They serve to obtain a general "first view", or panorama, of the distribution of the population, or of the sample, with respect to a characteristic, quantitative and continuous (such as length or weight).

5. Scatter Diagram

   • A scatter plot or scatter plot or bubble chart ball chart is a type of mathematical diagram that uses Cartesian coordinates to display the values of two variables for a data set.

6. Flowchart

   • It is the graphical representation of an algorithm or process. It is used in disciplines such as programming, economics, industrial processes and cognitive psychology.

7. Check Sheet

   • It is used to gather data based on the observation of the behavior of a process in order to detect trends, through the capture, analysis and control of information related to the process. Basically, it is a format that makes it easier for a person to take data in an orderly manner and according to the standard required in the analysis being performed.
