Quality Management Tools: A Complete Guide

quality management tool

Quality management Tools help employees of an organization find the defects. They make it easy to understand to understand and interpret information. Not only that but also they play a major role in removing problems and helping to find solutions. As a result, it increases the productivity and efficiency of goods and services, and last but not least the processes in various sectors to meet client’s needs..

Let us discuss the quality management tools and techniques.

Quality Management Tools


A Scottish engineer William Playfair introduces different types of charts along with pie charts and bar charts. A chart is the representation of data using various types of graphs. This is one of the important quality management tools, the visual representation simplifies the complex data. This kind of chart makes people easy to understand and identify each component of data and reveals the structure, pattern, trends, and relationship in data. The chart is generally linked with a worksheet. It automatically gets updated from time to time with the change in data. In quality management charts are one of the common forms of representing complicated data more efficiently.


A histogram is one of the quality management tools in project management, structurally similar to bar graphs. In the histogram, we can see there is a collection of bars where each bar represents different groups. The heights of the bars show the frequency of the data within that group. Along with that, data on the frequency can be broken into different categories. For example, sample size, months of the year, age, physical measurement, and many more. All are presented in numerical or chronological order. It is up to users, they can use the different outliers of the histogram to represent the distributional features of the data set variables.

As far as quality management tools are concerned, the histogram generally uses graphs in different fields for data analysis to manage quality. Quality professionals use a histogram to represent clean and clear frequency distribution among different sample groups which helps in the speedy identification of improvement areas within the system or process.

Scatter Diagram

A scatter diagram is one of the quality management tools, which uses dots to display the value of two different kinds of variables. The numeric data pairs from one variable on each axis. That is the X- axis, and Y- axis and if we have to find the relation. We need to join the dependent values on the Y-axis where every point shows a common interaction point. The dots or points generally fall along the curve or line if any correlation is found between the variables. If the correlation in the diagram is stronger, the relation between the two variables will be stronger. The dots come closer in the line if the correlation is strong enough. We can observe the correlation through a scatter diagram.

Control Chart

It is a graphical tool. The use of the tool is to study the process of change over time. Using this tool, the current data and historical data are compared to get a conclusion if an unpredictable variation comes into play. Consistent data signifies that the process is in control.  In quality management, professionals use this graph to save time as well as money for the organizations. This graph predicts and monitors the process performance with respect to the expectations of the clients or customers in the final product.

Check Sheet

The check sheet, in other words, is also called the tally sheet. It is a management tool for quality control. It is one of the most common quality management tools to control quality and every professional uses this tool for collecting quantitative and qualitative data. The check sheet becomes a tally sheet when used to collect quantitative data. The check sheet collects data in the form of tally marks or checks that represent specific values and enables users to quickly zero in on defects or errors within the system or process. It also helps to identify defect patterns to manage the quality.

Flow chart

The flow chart is also a graphical representation that divides the steps of a process systematically. Flow charts are basic quality-checking tools to document process flow and organizational structures. This is the reason that makes the flow chart an ideal quality management tool. In addition, it also determines the mechanism of process flow from one task to another. We can see the use of these diagrams in various fields like manufacturing, administration, service process, healthcare, research, and development, and they are widely used in academic projects.

Pareto chart

The chart consists of bars and a line graph in which the most basic problems, along with the repeatedly occurring defects are identified. The bar shows individual values in descending order. In the Pareto graph, the values are arranged vertically. Using the graph, users can find problems, solve them, and describe their frequency in the system.

Failure Mode and Effective Analysis 

Failure mode and effective analysis refer to the stepwise approach to calculate and find all the possible failures in a process, function, system, product, or service. FMEA is broadly bifurcating into two forms i.e. design (DFMEA) and process (PFMEA). DEMEA helps to identify faults and minimize product life, safety, and regulatory concerns. PFMEA reveals failure that affects the quality of products, reduces the reliability of the process, environmental problems, safety-related concerns, and customer dissatisfaction.

 Master Control

Master control is one of the best quality management tools, used in quality management. The tool Master Control documents enhance the efficiency of quality units and their effectiveness by automating routing assignments, tracking, scheduling follow-up, escalation, and evaluation along with the approval of all the document-based workings of the organization. The tools make easy the workflow and ease the overall operation. So that companies do not have to face quality degradation issues due to innovation costs

Affinity Diagram

The Affinity diagram is one of the best tools to manage quality. The use of the tool is to organize large amounts of data into related groups or themes based on their natural relationship. This process is particularly useful at the beginning of the problem-solving when information is very vast, scattered, or complex. The affinity diagram is helpful for the teams to categorize and understand information and helps them to identify patterns, themes, and solutions to a problem. 

quality management tools


Stratification is one of the important quality management tools. The use of the tool to sort data, people, or objects into various layers. The aim is to identify patterns or particular conditions that are not readily apparent when data is mixed. The process is specifically useful when data needs analysis to identify the source of variation or different types of information for more detailed analysis. This process involves dividing data into subcategories based on specific criteria such as time and location.
