Do you know the Seven Quality Tools?

The relentless pursuit of excellence in the production and delivery of products and services is a shared goal among organizations worldwide. To achieve this objective, quality management plays a crucial role, and an essential tool in this process is the famous "Seven Quality Tools." Are you familiar with them?

The Seven Quality Tools have a history dating back to the development of quality management and the evolution of statistical approaches to improve industrial processes. They were primarily developed in Japan and popularized by quality experts after World War II. Here`s a brief history of the Seven Quality Tools:


1.     Histogram: The idea of representing data in the form of a bar chart dates back to the early 20th century. The mathematician Karl Pearson developed the concept of histograms to visualize data distributions in statistics. However, the popularization of this technique in quality management was heavily influenced by Japanese quality experts after World War II.


2.     Pareto Chart: The Pareto Chart was developed by the Italian economist Vilfredo Pareto in the late 19th century. He observed that the majority of wealth was concentrated in the hands of a small percentage of the population. The same principle was applied to quality in Japan after the war, where experts realized that most problems were related to a small number of causes.


3.     Ishikawa Diagram: Also known as the Cause-and-Effect Diagram or Fishbone Diagram, this tool was developed by Dr. Kaoru Ishikawa, a Japanese engineer, in the 1960s. He refined the cause-and-effect diagram technique to help identify the root causes of quality issues.


4.     Check Sheet: The Check Sheet is a simple data collection tool with roots in the early days of scientific management, associated with Frederick Taylor and Frank Gilbreth. It was adapted for use in quality management over time.


5.     Scatter Plot: The Scatter Plot is a statistical tool that has been used to analyze the relationship between variables since the early 20th century. Its application in quality management was a natural extension of this technique.


6.     Flowchart: Flowcharts have a long history in engineering and process representation. They were adapted for quality management as an effective way to visualize and analyze processes.


7.     Control Chart: Control Charts were developed by Walter A. Shewhart in the 1920s as part of his work at Bell Telephone Laboratories. They became a fundamental part of the Statistical Process Control (SPC) methodology and were widely adopted in quality management.


In an increasingly quality-focused world, knowledge and application of these tools can be crucial differentiators. They empower teams to make informed decisions, improve processes, and deliver higher-quality products and services.
