Data about specific activities is entered into sheet to allow the study of product or process. Information about the frequency of occurrence of the events and its the place is important to further sheet analysis.

With the help of an analysis it is possible to collect specific data that can help find answers to questions such as:

  • How did analyzed the problem occurred?
  • How many times a specific problem happened?
  • Where the problem is located?
  • What is the cost of the errors?

The data can be placed into the sheet in the form of simple graphic characters. The control sheet should be constructed to be clearly seen for what purpose serves. This is a very effective and simple utility that primarily serves to collect and organize data from the performed measurements and observations.


Very often the tool is used to monitor the process or changes that were introduced to the process by the corrective or preventive actions. The quality managers use several types of control sheets, that help analyze:

  • specific features of the numerical distribution of the product or process,
  • frequency of occurrence of defects,
  • location of defects,
  • the cost of the occurrence of faults and defects,
  • the causes of defects and faults.
