Difference Between Quality Assurance and Quality Control

Difference Between Quality Assurance and Quality Control

Two terms sometimes interchangeably used are quality assurance and quality control (QC). While similar, the distinctions between the two definitions are distinct. This page will clarify and present concepts and concrete illustrations of the distinctions between quality control and quality management.

Difference Between Quality Assurance and Quality Control

Two types of quality management are quality assurance and quality control. While some practices in quality assurance and quality control are interrelated, they are described in a different way. In general, QA activities and duties are almost the entire quality scheme, whilst QC is a subset of QA activities. Quality systems components may also not be explicitly protected by the work and duties of quality assurance vs quality control but may include quality assurance vs quality control.

A project that any project manager uses as a criterion to verify the integrity of the project is often subject to 4 major restrictions. The cost, time, extent, and consistency of these four constraints. Quality in six sigma plays a key role in these 4 constraints because an experienced project manager would have to work again on the project, even though the project is completing within a given time, scope, and budget if your project does not comply with the quality requirements.

This is why the majority of businesses today concentrate more on quality control. Let us know about the Quality Control definitions and principles in six sigma certification.

Quality Assurance

Quality assurance

The quality assurance of all goods and services or of any specific project during each project stage ensures a certain predefined standard of quality.

Quality Control

It is the method of evaluating whether the goods follow the standard and finding any flaws and remedying it. Quality management refers principally to products rather than services.

quality control

The quality management systems and quality assurance lead to creating a culture of continuous product quality enhancement that allows the company to cut unnecessary expenses.

Both quality assurance and quality management systems lead to efficient resource usage by helping you to make the most productive use of available resources and prevent budgetary loss.

Quality assurance and quality assurance helps minimize the inspection costs by ensuring that the method is more confident and aware of the processes and the data obtained to help ensure a smooth service.

In almost all industries and sectors, both quality assurance and quality control are used, all approaches to quality management have their own value.

The phrases quality guarantee and quality management are most frequently treated as the same and often referred to as alternatives. Yet quality management and quality assurance vary from one another.

Although there is no correlation between quality control and quality assurance, their roots vary.

Initially, the definition of quality management includes quality assurance as well as quality control.

So now we know the importance of quality management and quality assurance. And the benefits the companies benefit from by successfully adopting them. Let us try and understand and find answers to the most common quality assurance/quality management issue – which is better. Let us understand by different methods the main difference between quality management and quality assurance.

Approach – Quality Assurance vs Quality Control

Quality Assurance: quality assurance is a prevention strategy. The holistic approach to determining the factors that could influence the quality of the product is quality assurance. Quality assurance concentrates on the planning, analysis, and determination of standards and guidelines to ensure the maintenance of the project’s quality standards. The Quality Assurance Plan specifies the standards and processes for ensuring the quality specified. After a review of customer feedback, a QA plan is developed.

Quality Control: Quality control is a detection strategy that includes all activities in order to determine the quality level of the products and services provided. Quality management requires quality tracking and all other quality assurance strategies. Quality management is a reactive process that does not concentrate on the manufacturing process, it focuses on the quality of the products already made. When the product has passed the stage of development, the activity of quality control comes out. It is used if any quality correction steps are to be taken during the production process.

Regulation of quality involves tasks such as product inspection, process inspection, etc. Quality management helps to avoid and reduce material waste by avoidance of the bottlenecks in processes. Quality management is planned to ensure that the ready-for-sale product has no defects.

Objective – Quality Assurance vs Quality Control

Quality Assurance – It helps to differentiate between quality management and quality assurance. The quality evaluation aims at enhancing development and test procedures so that the production processes and the development of the product do not include any quality problems. Quality assurance involves quality control, unit testing, safety testing, integration checks, performance tests, etc. In the early stages, a conservative project manager will implement procedures for quality assurance. Quality assurance helps to recognize and correct the deficiencies that were detected in the samples. It concentrates on avoidance and reparation.

Quality Control – Identifying and assessing whether any product defects after the stage of production is the main goal of quality control. Until putting it on the market, the company should ensure that goods manufactured are perfect and adhere to the quality standards. The relationship between quality management and quality assurance is very critical for professionals.

Orientation – Quality Assurance vs Quality Control

Quality Assurance: The method and guidance of quality assurance and quality management as discussed above are different. Quality assurance is a process-oriented assurance that focuses primarily on the development through the implementation of quality policies and procedures during the manufacture or rendering of any service. The organizations aim to identify whether quality problems arise at each level of development. When any changes are detected, prompt action will be taken. This method, therefore, allows the company to identify defects in the earlier stages, which is called quality assurance precautionary.

Earlier reporting aims to save time and costs for the organization. As corrective steps may require more costs after the product is made than the original cost of the product. Small improvements in the quality of the products of the company would have to be rejected particularly for the products to be exported.

Quality Control: In order to preserve consistency, both quality assurance and quality control are equally essential for an organism. Quality check plays an important part in these goods and services only after the product is manufactured for certain products. The business seeks customers’ reviews in order to know the output and customer satisfaction. Based on this information, the business will take quality improvement steps. Quality management is therefore referred to as a commodity approach. Only after manufacturing of the commodity can the tasks of quality control take place after delivery of a service to customers. Although quality assurance and quality control are orientated differently, most businesses both use the methodology to ensure that goods are provided to consumers with the highest possible quality.

Responsibility – Quality Assurance vs Quality Control

Quality Assurance: Quality assurance includes everybody in the team who is involved in manufacturing or production. Since quality assurance detects and evaluates defects in quality at manufacturing stages themselves. Although there is a distinction between QA & QC, the overarching reason why quality assurance against quality control comes in is the preservation of the quality. The same quality management role is carried out by quality insurance and quality control.

In a quality assurance system, it is everyone on the team who is responsible for maintaining the quality system, who all are accountable to the inspection officer, whether the manufacturing process varies or changes, and if the quality requirements have been established beforehand. Quality is the responsibility of the manufacturing department, while quality management is the responsibility of the instrument, procedure, and consulting department.

Quality Control: With respect to quality control, virtually every company will be set up to handle quality management activities by a particular team. The quality management duty rests entirely with the quality control and maintenance staff. The outcome or product is tested by this team. The quality management team members perform numerous monitoring activities to ensure that the product is within the finished product specification.

In the studies on Quality Control, the quality of the finished product is tested for scalability, load checking, defect reporting, and many others. The quality management team is the quality manager responsible. When we compare the quality management and the assurance of quality with regard to the obligation the teams have equal liability, but the quality control team does not have a separate team. Quality assurance and quality management are equal, their roles are different.

Final Thoughts

Today, our consumers become responsive to quality and the need for quality control in every sector has been increased. Quality assurance and quality management are not only used to ensure their goods and services to the consumers at the highest possible quality in a particular sector like the manufacturing industry and are used in almost all industries. Quality assurance and quality control are two opposite sides of a coin known as quality management, as discussed in this article. The company can opt for internal or external quality management systems, depending on the goods produced by the company.
