Leave a Mark – Focus on the Problem

The primary goal of quality control monitoring systems, commonly used in product manufacturing, is to eliminate defects. Only by tracking defects in semi-finished products, identifying and correcting root causes, can perfect products be produced. If you analyze quality control data statistically, the system will show you where the problems lie. The Defect Concentration Diagram (DCD) is a simple visual tool that helps collect and analyze data for this purpose. By marking different types of defects with different colors on a captured image of the product from every angle, it allows for data collection and visual analysis of this data, enabling focus on the correct problem area during the troubleshooting phase.

When is it used?

The Failure Density Diagram is effectively used in the following situations: for problem definition, when collecting data to show the effect of corrective actions on a product, when investigating a product manufactured with numerous defects, and when identifying the location of problems.

How to do it?

First, a Fault Density Diagram is designed, and the areas to be checked are drawn/photographed. The sections or areas to be drawn are prepared.

+ The diagram will be designed to show the errors. If necessary, the diagram will be improved based on feedback.

+ Data is collected via virtual reality tools or touch screens using specialized software.

+ The samples must be representative of the production process.

Even if multiple people collect the data, all data is organized collaboratively. In the Error Density Diagram, the location of each error is marked.

+ The Error Density Diagram is analyzed, and solutions are immediately developed by focusing on the problems. (The more data accumulated on error density, the more accurate the conclusion can be.)
