Study on a Determination of Measures Needed to Improve the Quality of Analyzes Performed in a Chemical Laboratory

In this paper the authors present a study on the use of the tree diagram to solve a quality problem in a chemical laboratory. The study aims to identify actions/measures that ensure elimination of sources of errors that cause non-quality problems in analyzes performed in a chemical laboratory. Several measures have been identified that have been grouped into four categories corresponding to four specific objectives. There was a relatively complex 4-level tree diagram. The specified tree chart is useful for organization management and staff in the chemical laboratory to prevent and eliminate nonconformities and generally to improve the quality of the deployed activities.
