    Maintaining quality is a critical aspect of every successful organization. Customers must be provided with products and services that are convenient for them and, as a result, worth the money they spend. In order to be successful in company, we must always keep in mind that the most important goal is client pleasure.
    Businesses should utilize the Seven Quality Control tools to ensure that the best possible products and services are offered to customers on a continuous basis (7 QC Tools). The efficient and successful application of these 7 quality control methods can aid in maintaining the consistency of the products and services offered. The use of these tools is dispersed throughout the DMAIC process’s many phases.

    Why should you employ the seven quality control tools?
    The 7 QC tools are a series of graphical techniques that have been found as being particularly useful in diagnosing quality concerns. The seven quality control tools are essential tools for improving process and product quality. They are used to inspect the manufacturing process, detect critical concerns, regulate product quality fluctuations, and provide remedies to prevent future defects.
    These are the instruments that make it easier for an organization to solve basic issues. When a company embarks on a quality improvement journey, there are always a lot of low-hanging fruit that can be dealt using these basic 7 QC tools. These seven quality control methods are simple to comprehend and use, and they do not necessitate advanced analytical or statistical skills.

    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.

    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, 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;
    Check sheet
    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.
