What are the 7 qc tools used in quality management?

[Jake Able]

The following is a list of the seven quality control tools:
The American Society for Quality (ASQ) has established seven quality control instruments that are widely used in the quality engineering community:
Diagram of Cause and Effect
Fishbone Diagram (also known as Cause and Effect Diagram) is a type of cause and effect diagram. A diagram can assist in determining the possible causes of an effect or problem. It assists in understanding the areas of opportunity through good brainstorming in addition to organizing thoughts into appropriate categories. Fishbone training enables you to pinpoint the problem’s root cause.

Chart of Controls
Control charts are used to investigate how processes have evolved over time. Furthermore, by comparing current data to previous control limits, one can determine if process variation is consistent (under control) or unpredictable (out of control) as a result of being affected by special causes of variation.

Pareto Diagram
The Pareto Chart is based on the 80/20 rule, and it displays the major components that have the most impact on the problem at hand.

Sheet of Checks
A check sheet is a method for collecting and assessing data in an organized manner. It’s a versatile tool that may be used for a number of tasks.

Histogram
A histogram is a graph that displays data and its frequency of distribution to assist users in identifying each unique value in a batch of data.

Diagram of Scatter
The scatter diagram depicts the relationship between two essential components, such as numerical data pairs, with one variable on each axis to show the link.

Stratification
Stratification, often known as a flow chart or run chart, is a technique for separating data from several sources so that patterns, such as the path an object has traveled through a particular process, may be seen.
Using the seven quality control tools in the six sigma or quality management process allows for a systematic approach to identifying and understanding risk, assessing risk, controlling product quality fluctuations, and providing remedies to avoid future errors.

When should you use the 7 Quality Control Tools?
For improved quality management, 7 QC tools can be used throughout quality management, quality improvement procedures, six sigma implementation processes, or even the conventional PDCA cycle. Fishbone Diagram, also known as a cause and effect diagram, Pareto Chart, and Control Chart can be used in the first phase of measuring and identifying. Scatter Diagram, Histogram, and Checklist can be used in the next stages of assessment and analysis. The Control Chart can be used to maintain a high level of quality.

Quality Tools: What Are They?
The 7 basic tools of quality, sometimes also referred to as 7 QC tools – represent a fixed set of graphical tools used for troubleshooting issues that are related to quality.

They are called basic quality tools because they can be easily learned by anyone even without any formal training in statistics. Dr. Kaoru Ishikawa played the leading role in the development and advocacy of using the 7 quality tools in organizations for problem-solving and process improvement.

The 7 basic quality tools include;
Flowchart
Check sheet
Histogram
Pareto chart
Control chart
Scatter diagram
Cause-and-effect diagram
Quality tools are used to collect data, analyze data, identify root causes, and measure results in problem-solving and process improvement. The use of these tools helps people involved easily generate new ideas, solve problems, and do proper planning.

The 7 quality tools were first emphasized by Kaoru Ishikawa a professor of engineering at the University of Tokyo, who is also known as the father of “Quality Circles” for the role he played in launching Japan’s quality movement in the 1960s.

The 7 QC tools are thought to have been introduced by Kaoru Ishikawa in postwar Japan, and were inspired by the seven renowned Benkei weaponry. Benkei was a Japanese warrior monk who carried seven weapons and set out on a personal mission to steal 1,000 swords from samurai soldiers he considered haughty and dishonorable.

A series of lectures on statistical quality control given by Dr. W. Edwards Deming to a group of Japanese scientists and engineers in 1950 impacted Ishikawa. Unfortunately, most workers were overwhelmed by the subject’s intricacy, so Ishikawa concentrated on a smaller set of tools that would suffice for most quality-related difficulties.
