Posted by Allison Lynch | 01/14/2021

When it comes to problem-solving or decision-making, the Cause and Effect Analysis certainly proves extremely beneficial. Ideally, you can come up with a detailed Cause and Effect diagram to explore or dissect any problem. Also known as a fishbone diagram, the Cause and Effect analysis is mostly done via a 6M model. In this post, I will let you know about the 6M model to create Cause and Effect diagrams like a pro.

Part 1: What is the 6M Method for Cause and Effect Analysis?

The Cause and Effect Analysis is a popular problem-solving technique that identifies the likely causes for an issue and undertakes its effect to fix it. For any problem, there can be different causes that are represented in a Cause and Effect Diagram.

To identify and explore these causes and effects, the 6M model is incorporated. It is mostly implemented in production and other industries where it is easier to examine the causes of a problem. The 6M method of Cause and Effect Analysis is based on the following parameters:

  • Manpower
  • Machine
  • Material
  • Method
  • Mother-nature
  • Measurement

Part 2: How to Apply the 6M Method in Cause and Effect Analysis?

Also known as a fishbone or an Ishikawa model, the Cause and Effect diagram is centered on a problem and its prospective causes. If you want to perform the 6M method on the Cause and Effect analysis, then you can go through the following steps. We will try to understand it via the following example in which we will identify what causes a delay in lab results.

Identify the problem: At first, you know to define the problem that we wish to solve. In this case, it is the delay in the processing of lab results. While making a fishbone diagram, you can depict it at the center.

Manpower: In the first analysis, you can look into different manual causes (like manpower or labor) for the problem. In this case, it can be the absence of the patient or the delay in collecting the specimens.

Material: The next stage of Cause and Effect analysis would identify causes related to materials and raw components. Shortage or faulty materials can be some major causes in this case.

Measurement: As the name suggests, this would analyze the error or fault in the measurement of the lab specimen. Calibration errors can also be a major cause included in this category.

Machine: Apart from the measurements, chances are that the machines for calculating results could be faulty. The lack of appropriate machines can also be included in this.

Methods: Next is the overall analysis of the production or evaluation process. In this, we can identify the overall method that could have tampered with the lab results.

Mother-nature: Lastly, you can have a look at other environmental and uncontrollable circumstances (like a sudden change in temperature) that could have caused the problem.

Part 3: Some Cause and Effect Diagram Examples to Learn From

Now when you know how to perform the Cause and Effect Analysis with the 6M method, let’s consider a few examples. This will help you understand the applications of the Cause and Effect diagram in the real world.

Example 1: Reasons for Employee Resignation

In this first Cause and Effect diagram example, we have tried to diagnose the various reasons for an employee’s resignation.

Apart from the 6 major factors, we have considered other scenarios like salary, work environment, health, residence, management, workload, and other factors. All these factors have been further explored, considering the possible causes for employee resignation and their effects.

Example 2: Results of an Academic Record

In next Cause and Effect diagram, you can explore the numerous possibilities for one’s academic results. In this, we have considered things like one’s learning abilities, teaching, learning strategies as well as intelligent and non-intelligent factors that can affect their result.

Example 3: Low Customer Satisfaction

Lastly, you can check the Cause and Effect diagram for low customer satisfaction. Ideally, things like high price, low-quality product, poor customer support, and management are some of the major causes of the lack of customer satisfaction. All these causes are further explored in this Low Customer Satisfaction fishbone diagram.
