7 QC Tools Training Material PPT Free Download
If you are looking for a simple and effective way to improve the quality of your products or processes, you may want to learn about the 7 QC Tools. These are seven basic quality management tools that can help you solve quality-related problems, reduce defects, increase customer satisfaction, and save costs. In this article, we will explain what the 7 QC Tools are, why they are important, how to use them, and where to find free PPT templates for them.
What are the 7 QC Tools and Why are They Important?
The 7 QC Tools are a set of visual exercises that were developed by Kaoru Ishikawa, a Japanese professor of engineering and a pioneer of quality management. He introduced these tools in the 1950s to help workers of various technical backgrounds implement effective quality control measures. The 7 QC Tools are also known as the 7 Basic Quality Tools or the 7 Old Quality Tools. They are:
Definition and examples of the 7 QC Tools
- Cause-and-effect diagram: Also called Ishikawa diagram or fishbone diagram, this tool helps identify and analyze the root causes of a problem or an effect. It sorts ideas into useful categories and shows the relationship between causes and effects.
- Check sheet: Also called tally sheet, this tool helps collect and organize data in a structured and prepared form. It can be adapted for a wide variety of purposes, such as counting defects, recording observations, or tracking events.
- Control chart: Also called Shewhart chart, this tool helps monitor and control the variation and stability of a process over time. It compares current data to historical control limits and indicates whether the process is in control or out of control.
- Histogram: This tool helps display the frequency distribution of a data set. It shows how often each different value in a set of data occurs and reveals the shape, spread, and central tendency of the data.
- Pareto chart: This tool helps prioritize the most significant causes of a problem based on the 80/20 rule. It shows which factors are more frequent or more important than others and helps focus on the vital few rather than the trivial many.
- Scatter diagram: This tool helps examine the relationship between two variables. It graphs pairs of numerical data, one variable on each axis, and looks for a correlation or a pattern.
- Stratification: Also called flow chart or run chart, this tool helps separate or classify data into different groups or categories. It helps reveal patterns or trends that might not be visible when the data is mixed together.
Benefits and applications of the 7 QC Tools
The major benefits of using the 7 QC Tools are:
- They help analyze and solve quality problems effectively.
- They improve product and process quality.
- They reduce defects and waste.
- They increase customer satisfaction and loyalty.
- They save time and money.
The 7 QC Tools can be applied to various industries and situations, such as manufacturing, service, healthcare, education, engineering, project management, etc. They can be used for different purposes, such as quality planning, quality assurance, quality control, and quality improvement.
How to Use the 7 QC Tools for Quality Improvement
The 7 QC Tools can be used in a systematic way to solve quality problems and improve quality performance. A common approach is to follow the Plan-Do-Check-Act (PDCA) cycle, which is a four-step method for continuous improvement. The PDCA cycle consists of the following steps:
Step 1: Identify the problem or opportunity
The first step is to define the problem or opportunity that needs to be addressed. This involves clarifying the scope, objectives, and expected outcomes of the improvement project. Some questions to ask are:
- What is the problem or opportunity?
- Why is it important?
- Who is affected by it?
- What are the current and desired states?
- How will success be measured?
Step 2: Collect and organize data using check sheets and stratification
The second step is to collect and organize relevant data that can help understand the problem or opportunity better. This involves gathering information from various sources, such as customers, suppliers, employees, documents, records, etc. Two tools that can help with this step are check sheets and stratification.
A check sheet is a simple form that can be used to record data in a structured way. It can help count the frequency of occurrences, events, defects, or errors. For example, a check sheet can be used to track the number and type of customer complaints, defects in a product, or errors in a process.
Stratification is a technique that can be used to separate or group data into different categories or layers. It can help reveal patterns or trends that might not be visible when the data is mixed together. For example, stratification can be used to analyze data by product type, customer segment, location, time period, etc.
Step 3: Analyze the data using histograms, Pareto charts, and scatter diagrams
The third step is to analyze the data that was collected and organized in the previous step. This involves using graphical tools that can help display and interpret the data visually. Three tools that can help with this step are histograms, Pareto charts, and scatter diagrams.
A histogram is a type of bar chart that can be used to show the frequency distribution of a data set. It can help show how often each different value in a set of data occurs and reveal the shape, spread, and central tendency of the data. For example, a histogram can be used to show the distribution of cycle times, defect sizes, or customer satisfaction ratings.
A Pareto chart is a type of bar chart that can be used to prioritize the most significant causes of a problem based on the 80/20 rule. It can help show which factors are more frequent or more important than others and focus on the vital few rather than the trivial many. For example, a Pareto chart can be used to show the most common types of defects, customer complaints, or process delays.
A scatter diagram is a type of plot that can be used to examine the relationship between two variables. It can help graph pairs of numerical data, one variable on each axis, and look for a correlation or a pattern. For example, a scatter diagram can be used to show the relationship between temperature and pressure, speed and fuel consumption, or customer satisfaction and loyalty.
Step 4: Identify the root causes using cause-and-effect diagrams
The fourth step is to identify the root causes of the problem or the factors that influence the opportunity. This involves using a tool that can help brainstorm and organize possible causes and effects. A tool that can help with this step is a cause-and-effect diagram.
A cause-and-effect diagram is a type of diagram that can be used to identify and analyze the root causes of a problem or an effect. It can help sort ideas into useful categories and show the relationship between causes and effects. It is also called Ishikawa diagram or fishbone diagram because of its shape. For example, a cause-and-effect diagram can be used to show the possible causes of low customer satisfaction, high defect rate, or poor process performance.
Step 5: Monitor and control the process using control charts
The fifth and final step is to monitor and control the process that was improved in the previous steps. This involves using a tool that can help measure and track the variation and stability of the process over time. A tool that can help with this step is a control chart.
A control chart is a type of chart that can be used to monitor and control the variation and stability of a process over time. It can help compare current data to historical control limits and indicate whether the process is in control or out of control. It is also called Shewhart chart because it was developed by Walter A. Shewhart, an American physicist and engineer. For example, a control chart can be used to monitor and control the cycle time, defect rate, or customer satisfaction of a process.
