Learn about quality management, tools, and other techniques to determine the root cause of a problem. Ensure the delivery of quality products to meet customer satisfaction.
Published 16 Sep 2021
Quality management provides an agile framework to implement effective quality and productivity initiatives in every aspect of business operations. It focuses on improving the standards of organizational deliverables to meet customer needs and expectations such as performance, availability, reliability, and value for their money. Quality management guides the organization in maintaining the production of high-quality products and aims to eliminate substandard or waste products to consistently achieve customer satisfaction and promote an overall good business.
Being unable to meet customer expectations can lead to customer attrition, profit loss, and damaged business reputation. Quality management oversees all the activities and creates an efficient process to allow the teams to focus on high-impact activities to ensure continuous improvement on products or services and deliver with high quality.
To provide customers with quality products and services, the management team utilizes quality management tools that can empower them to efficiently manage and perform audits to evaluate activities based on observation and analysis. It was originally developed by Kaoru Ishikawa, a Japanese professor of engineering at Tokyo University, to show simple graphical and statistical techniques to solve quality-related issues. There are seven basic quality management tools identified as follows:
These tools are used to identify possible causes of a problem based on observation and collected data including frequency, area, defects, and similar issues.
The cause and effect diagram, also known as the fishbone diagram, helps identify possible causes of an issue using a template with a resemblance to a fishbone. Quality management teams can identify a quality-related problem on the right-hand side of the diagram, with individual root causes and sub-causes branching off to its left. Mostly, categories such as methods, equipment, people, environment, and materials are used to identify the possible cause of the problem.
A check sheet is a structured presentation of gathered data that are collected repeatedly by the same person from the production process. It helps identify defects based on type, location, or cause. It records preliminary data distribution and its frequency when measuring out processes indicating the number of times a particular value has occurred. It allows quality management teams to eliminate defects or errors within the processes, products, or services.
A control chart is also known as the Shewhart chart and is used to study the changes in the process over time. It shows whether the process variation is in control or is affected by different causes of variation, which is based on a comparison of historical control limits and current data. A control chart makes it easy for quality managers to identify factors that may lead to variations or defects considering whether a process is stable or predictable.
A Pareto chart is used to identify the most significant issue in the production processes that needs immediate rectification. It uses a combination of line and bar graphs to present the frequency of issues in the production process. It highlights the relative importance of a variety of parameters to analyze and determine the most impactful factor on a specific process or system. Quality managers can sort the number of defects from the largest to the smallest occurrences in order to identify which to prioritize in terms of improvement efforts.
The stratification analysis helps quality managers divide different factors such as objects, data, and people into distinct groups to determine the revealing patterns that are not visible when those factors are lumped together. It is used when data comes from different sources and analysis may require sorting out from these sources. It can be presented in combination with other data analysis tools to identify the circumstances that could affect the quality of delivery.
A histogram is utilized to show frequency distribution using numerical data. It is somehow similar to a bar graph as it shows patterns that fall within common process conditions. It helps quality management teams analyze the output from the processes of suppliers and check whether a process has changed from one period to another. It can be presented in different shapes as follows:
A scatter diagram is the most useful tool in describing the cause and effect relationship between two variables. It uses the X and Y axis to look for relationships between quality defects and possible causes including activity, personnel, environment, and other variables. It helps determine whether two effects that appear to be related occur with the same source.
Quality managers are responsible for maintaining the high value of products or services and ensure they consistently achieve customer satisfaction. It is vital to spot quality or product-related issues and defects early on before they reach end-production to avoid business damage. To efficiently perform their duties, they use quality management tools to identify issues and apply immediate corrective actions. Some of their tasks include the following:
Task #1: Data gathering
Data gathering is a crucial part to identify the cause and effect of an issue or defect. It is the starting point in creating hypotheses to identify the root cause of a problem. Collected data should be accurate and reliable to formulate appropriate insights and analysis.
Task #2: Identify the problem
The different quality management tools used to identify the problem depend on the needs of the company. It is vital to identify the cause of the problem in order to ensure the quality of products or services.
Task #3: Perform quality checks
Traditionally, the pen and paper method was used to perform quality checks. This method has allowed quality management teams to complete their task, but it can be difficult to track over time as critical data can get lost in the process. With iAuditor by SafetyCulture, a web and mobile quality inspection app, quality managers can achieve the following.
Yes. As technology progresses, there are other tools and philosophies quality managers can utilize to ensure customer satisfaction. It has been developed to focus on quality control to eliminate waste. To get you started we have prepared ready-to-use templates that are highly customizable according to your business needs.
ISO 9001 is a global industry standard that provides a framework and specifies best practices and requirements to help organizations identify and discover potential improvements. It helps address issues and ensures that process best practices are in place. An ISO 9001 internal audit checklist is used to identify and analyze gaps that can help the organization to prepare for ISO 9001:2015 certification.
Total Quality Management (TQM) is a comprehensive system of planning and control of all business functions that aim to produce products or services that would meet customer expectations. The use of a manufacturing quality control checklist can help quality teams maintain standards across business operations.
Failure Mode and Effects Analysis (FMEA) is a standardized method of predicting potential failures in business processes and alleviating their impact on customers. An FMEA template is utilized to help quality management teams identify potential problems in a process,
product, or design to prevent negative effects on the business.
Kaizen is primarily implemented in manufacturing industries to eliminate the following 8 wastes:
It helps management teams to monitor and implement continuous improvement efforts in the workplace. A kaizen report template is a useful tool to present changes in tasks or processes after continuous improvement efforts and helps identify the root cause of the problem.
Six Sigma is an organizational cycle that aims to spot quality errors to achieve a low defect rate. It sets a benchmark for production and administration systems including operations, human resources, purchasing, and customer services to achieve efficiency and excellence in every process. It helps the organization to gain control of the quality of its processes by implementing a measurable approach to determine the causes of defects. Utilizing a DMAIC template, based on one of the most commonly used six sigma methodologies, can help quality management teams identify process improvements.
