6M Method for Cause and Effect Analysis

> Business Diagram Knowledge > 6M Method for Cause and Effect Analysis
Posted by Allison Lynch | 10/10/2020
The 6M method is widely used in cause and effect analysis and proved to be effective. It can help us identify the root cause of the defects that are causing variation in our process.

6M Method and Cause and Effect Analysis

It is recommended to categorize factors in cause and effect analysis so that readers can understand them better. During the discussion and draft phases of cause and effect analysis, the 6M method can be applied. The 6M stands for manpower, machinery, materials, methods, measurement, and mother-nature. Below is the detailed illustration of the method.

1. Manpower. Whether the personnel's technical proficiency and experience are up to standard? Does the staff have quality consciousness, sense of responsibility, and discipline?

2. Machinery. Check the facilities' stability, functionality, such as the GPS device's precision and the cooling and lubrication state of equipment. If the machinery is rusting or eroding, the production efficiency may decrease. Find out solutions to regularly maintain and repair equipment.

3. Materials. Think about the materials' components, physical and chemical properties. Examine whether different parts match well. Are our material suppliers stable or not?

4. Method. To be more specific, the methodology, methods, or techniques will affect the action's result. Other factors concerned are workflow, choice of technical parameters, technical guidance, and the preciseness and execution of a workflow.

5. Mother-nature. In plain English, the environment in the production field, including temperature, humidity, noise disturbance, vibrancy, lightening, and indoor pollution will all influence the products or services.

6. Measurement. When it comes to measurement, the following factors need to be considered for correct results: measurement gauge, measurement method, calibration, measurer's fatigue, and readability of the results.
