Top 15 Quality Management Tools For 2025

Quality management tools (QMT) provide an organization's employees with support to discover recurring errors, their root causes and sub-causes, and their impact. Quality control tools play an important role in eliminating problems and finding opportunities for improvement. Additionally, Quality Management helps companies find solutions that improve the productivity and efficiency of goods, services, and processes in various sectors (manufacturing, services, healthcare, etc.)  in order to meet customer and customer expectations.

 

15 Quality Management Tools and Techniques

 

1. TQM (Total Quality Management)

TQM is elaborated as total quality management and was first introduced by W. Edwards Deming. It is an integrated, comprehensive system that plans and coordinates all operations within a company to produce processes and products that meet customer expectations. TQM is a collection of business behavior philosophies (such as employee participation and continuous improvement of standards) and related techniques for improving quality (such as clear goals and performance evaluation). 

 

2. Checklist

In 1935, Checklists were first invented by Boeing. A checklist is a list of items, information, and important considerations related to quality assurance activities. This list helps users search and plan their quality control activities. This helps quality control and quality assurance keep his to-do list in mind and tailor it to individual needs. The checklist covers product requirements, packaging requirements, on-site product testing and inspection, defect classification, and collaboration between parties and members involved in the system, such as suppliers, manufacturers, line assemblers, and quality assurance inspectors which provides insight. 

 

3. Master Control

 

Master Control is one of the best quality control tools that is not listed on a stock exchange. MasterControl Document Tools increases the efficiency and effectiveness of your quality department by automating the routing or task assignment, tracking, follow-up, escalation and evaluation, and approval of all your organization's document-based work, processes, and systems. It will help you. These tools simplify workflows and make overall operations easier, so companies no longer face quality degradation due to regulatory or cost innovations. 

 

4. Failure Mode and Effects Analysis

In the late 1940s, the U.S. military developed Failure Modes and Effects Analysis (FMEA). It refers to a step-by-step approach to estimating and discovering all possible defects in a process, function, system, product, or service. FMEA is broadly divided into two forms: design (DFMEA) and process (PFMEA). DFMEA helps detect malfunctions and alleviate product life, safety, and regulatory concerns. In contrast, PFMEA uncovers defects that impact product quality, reduced process reliability, environmental hazards, safety concerns, and customer dissatisfaction. 

 

5. Kaizen

Kaizen was introduced to Japan by Masaaki Imai in 1986. In Japanese, Kai refers to "change" and Zen refers to "good", meaning change or improvement for the better. This quality management approach is defined as a continuous effort by every member of the organization, from the CEO to the field staff, to improve all of the organization's systems and processes to deliver rapid results. Kaizen usually has important elements such as teamwork, personal discipline, improving work ethics, quality circles, and suggestions for improvement. 

 

6. Gap Analysis

Michael Scott devised the gap analysis process in his 1980s. Gap analysis is one of the most useful quality management processes that helps companies understand the process of achieving business goals. The current state is compared to a standard or ideal state to determine deficiencies and areas for improvement in an organization's processes or systems. This process includes assessing the current state, identifying the ideal future state, assessing gaps and identifying solutions, and creating and incorporating plans to fill the gaps to effectively improve the system.  

 

7. Pareto Principle

The Pareto Principle, also known as the 80/20 rule, was made by economist and Italian philosopher Vilfredo Pareto in 1896. This rule specifies that 80% of the outcome or outcome is controlled by 20% of the factors or activities. For example, a company derives 80% of its profits from 20% of its product types. This rule is widely accepted in a variety of fields, including healthcare, manufacturing, finance, project planning, and inventory management.

 

8. Flow chart

In the year 1921, Flowcharts were created by industrial engineers Frank Gilbreth and Lillian Gilbreth. This is a graphical representation that systematically separates the steps of a process. Flowcharts are one of the basic quality control tools for documenting process flows and organizational structures. This approach makes flowcharts an ideal quality control tool for finding bottlenecks and unnecessary steps within a system or process. 

Additionally, mapping processes allows you to effectively identify activities, such as who performed tasks within the process and when. Flowcharts also determine the mechanism for process flow from one task or department to another, and the steps that are removed from a process or system. These diagrams are commonly used in many fields such as manufacturing, management, service processes, healthcare, research and development, and academic projects. 

 

9. Pareto Chart

The Pareto chart or Pareto distribution chart was introduced by the Italian economist and sociologist Vilfredo Pareto in the early 20th century. This chart consists of a bar chart and a line chart that identifies the most common issues and the most common errors. The bars represent individual values in descending order, while the line shows the cumulative total in the shopping cart. In a Pareto chart, the values are plotted vertically. This chart allows users to spot and prioritize issues and describe their frequency in the system.  

In quality control, the Pareto chart functions as the 80/20 rule. This rule predicts that 80% of system or process failures can be attributed to 20% of the key factors, often referred to as "critical views." On the other hand, 20% of errors and problems are caused by 80% of secondary factors.  

 

10. Check Sheet

 

The Check Sheet, also called the tally sheet, is a management tool for quality control . It is one of the most common tools for collecting qualitative and quantitative data. Control sheets are especially called tally sheets when they are used to collect quantitative data. 

Check sheets collect data in the form of lines or checks that represent specific values that occur repeatedly, allowing users to quickly identify deficiencies or errors in a system or process. It also helps you control quality by identifying patterns of errors and identifying the causes of specific errors in your processes and systems. 

 

11. Ishikawa Diagram

 

The Ishikawa Diagram, commonly referred to as the fishbone diagram or cause-effect diagram, is one of his world-class quality control tools developed by Dr. Kaoru Ishikawa in 1945. Kaoru Ishikawa was introduced. The term fishbone is derived from its resemblance to the skeleton of a fish. However, cause and effect names are based on the diagram's ability to record the cause of a particular error.

This diagram is very important in quality control to identify the cause of specific defects and potential factors contributing to general problems in a process or system. This diagram helps you break down complex problems and systematically focus on a particular problem from different perspectives. The diagram is structured so that quality issues are shown on the right side of the diagram, and their root causes or root causes and sub-causes are shown separately on the left side of the diagram. 

There are six elements (6M) of causes and sub-causes in manufacturing. Measurement, materials, labor (people/staff), environment, methods (process), machinery (equipment). As the industry changes, these factors change accordingly.

For example, 6M is replaced by 8P in product marketing and 4S in the service department.

 

12. Pie / Bar  Charts 

In 1786, Scottish engineer William Playfair introduced several types of charts, including pie charts and bar charts. A chart is defined as a graphical representation of data. In quality control, visual representations simplify complex data. It helps you identify and understand each component of your data and uncover structures, patterns, trends, and relationships within your data. 

Charts are usually linked to worksheets. Automatically updates in real time as data changes. In quality control, diagrams are one of the most common formats for representing complex data more efficiently. 

 

13. Histogram

Karl Pearson introduced the histogram in 1891. Histogram is one of his quality control tools in project management, its structure is similar to a bar graph. There is a smart collection of bars, each bar representing a different group. The height of the bar indicates the frequency of data within this group. Additionally, frequency data can be easily categorized into categories such as sample size, month, age, and body measurements, and can be viewed numerically or chronologically. Users can (optionally) use different outliers in the histogram to represent distributional characteristics of data set variables. 

 

In quality control, histogram is one of the most commonly used graphs in various fields for data analysis and operation interpretation of various quality control groups. Quality professionals use histograms to represent clear and concise frequency distributions among different sample groups. This helps quickly identify areas for improvement within a system or process.

 

14. Scatter Plot

A Scatter Plot, also known as a scatter diagram, scatter chart, or scatter graph, was invented in 1833 by John F.W. Herschel. The graph is utilized for points to display the values of two different numerical variables. The numerical data consists of one variable for each axis. Combine the x and y axes and determine their relationship. Dependent values on the Y-axis and independent values on the X-axis must be connected at each point with a common intersection. If a correlation is found between variables, points or dots are displayed along the curve or line.

The stronger the correlation in the diagram, the stronger the connection between the two variables. The stronger the correlation, the closer the points are to the line. Correlations can be observed through scatterplots. Positive correlation, negative correlation, and no correlation (none) are indicated. 

In quality control, scatter plots are used to identify relationships between two variables to understand quality defects, their possible causes (personnel, activities, environment, or other variables), and their impact on a system or process. Helpful. Recognizing and understanding the relationships between variables makes it easier to implement desired solutions to solve problems and achieve desired results. 

 

15. Control Card

A control chart also known as Stewart control chart is a QM tool developed by Walter A. Stewart in 1924 and is a graphical tool for examining processes of change over time. It compares current and historical data to determine whether process variations are consistent or unpredictable. Consistent data indicates the process is in control. In contrast to it, unpredictable data is data that is out of control due to certain variables. 

In quality control, this chart is often used by professionals to save companies time and money by predicting and monitoring the performance of processes in relation to customer expectations for the final product.
