We frequently take the dependability and quality of goods and services for granted in today’s society. However, quality control in manufacturing was not exactly a dependable procedure during the start of the 20th century.
It’s now easier than ever for a company to adopt and grow best practises, decades after early pioneers developed frameworks for analysis and problem-solving in the business world to identify and manage value and consistency.
What Is Quality Control (QC)?
There is no one definition of quality. Quality control, with different meanings of “value,” refers to the method by which goods and services are examined and evaluated to make sure they live up to expectations.
A company can assess, maintain, and enhance product quality with this method. Finding and fixing any deviations from the set quality standards is the main goal of quality control.
In order to make sure that goods and services match the required standard of quality, this procedure entails tracking and examining them at several points during manufacturing or delivery.
By putting policies in place to regulate and enhance the production or service delivery processes, quality control (QC) also aims to stop errors or faults before they start.
Key Components of Quality Control
- Inspection: Regularly examining products, materials, or services to identify defects, non-compliance, or deviations from quality standards.
- Testing: Conducting various tests and measurements to assess the performance, functionality, or characteristics of products or services.
- Statistical Process Control (SPC): Employing statistical techniques to monitor and control the production processes, ensuring that they remain within acceptable quality limits.
- Documentation and Records: Keeping detailed records of inspections, tests, and corrective actions taken to maintain traceability and accountability.
- Corrective Action: Implementing appropriate measures to address any identified quality issues and prevent their recurrence.
- Training and Education: Providing employees with the necessary skills and knowledge to maintain quality standards effectively.
- Continuous Improvement: Constantly analyzing data and feedback to identify areas for improvement and enhancing the overall quality management system.
Quality Control and Quality Assurance (QA), two other concepts in quality management, are closely related. Although quality control (QC) works on finding and fixing errors, quality assurance (QA) focuses on avoiding errors from happening in the first place by establishing reliable systems and procedures.
The foundation of a company’s quality management system is made up of QC and QA working together to guarantee that goods and services continuously meet or surpass consumer expectations and legal requirements.
Quality Control Process
Quality testing is frequent at each level of the production or commercial process. Workers often start testing with raw materials, completed goods, and samples taken from the production line. Testing at different stages of production can assist in determining the root cause of an issue and the steps that need to be taken to fix it so that it doesn’t occur again.
Inspections, audits, questionnaires, surveys, and customer service reviews are a few types of quality assessment methods that are applicable to non-manufacturing companies. Any process or method can be employed by a business to guarantee that the finished good or service satisfies customer needs, is safe, and complies with regulations.
Types of Quality Control
Similar to how quality is a relative term with multiple meanings, quality control lacks a standard operating procedure. Certain techniques are industry-specific. Consider food and drug items, for example, where mistakes might endanger public health and result in serious legal consequences. Certain industries (like coaching or education) might need a more comprehensive, qualitative approach, while others might rely more heavily on scientific measurements.
Fundamentally, research methods and attention to detail are necessary for quality control.
Describe quality control, then. Numerous techniques exist for quality control, such as:
Control Charts:
A graph or chart is used to study how processes are changing over time. Using statistics, the business and manufacturing processes are analyzed for being “in control.”
Process Control:
Processes are monitored and adjusted to ensure quality and improve performance. This is typically a technical process using feedback loops, industrial-level controls, and chemical processes to achieve consistency.
Acceptance Sampling:
A statistical measure is used to determine if a batch or sample of products meets the overall manufacturing standard.
Process Protocol:
A mapping methodology that improves the design and implementation processes by creating evaluative indicators for each step.
When choosing a technique, there are more quality control considerations than only process types.
To define quality control, several businesses create internal departments dedicated to the task. Some use this to keep an eye on goods and services, while others depend on other organisations to keep tabs on goods and output. The business’s industry may have a significant impact on these controls. For example, because food inspections are so stringent, it could be ideal for a business to sample its products internally and confirm the results in a third-party lab.
Why Is Quality Control Important? What Are the Benefits?
Quality Control (QC) is important for many reasons, and its value is derived from the many advantages it offers to customers and organisations alike. Here are a few main justifications for why QC matters:
- Customer Satisfaction: QC ensures that products and services meet or exceed customer expectations, leading to higher satisfaction levels and increased customer loyalty.
- Defect Prevention: By identifying and correcting issues early in the production or service delivery process, QC helps prevent defects, reducing the likelihood of expensive recalls or rework.
- Cost Reduction: Implementing QC measures can lead to reduced waste, lower production costs, and improved operational efficiency, contributing to overall cost savings.
- Compliance and Regulations: QC ensures that products and services adhere to industry standards and regulatory requirements, avoiding legal issues and penalties.
- Brand Reputation: Consistent high-quality products or services build a positive brand image, enhancing the company’s reputation and competitiveness in the market.
- Increased Efficiency: QC optimizes processes and identifies areas for improvement, leading to increased productivity and streamlined operations.
- Risk Mitigation: Through rigorous testing and inspections, QC helps identify potential risks and hazards, enabling businesses to address them proactively.
- Continuous Improvement: QC encourages a culture of continuous improvement, where organizations strive to enhance their products, services, and processes constantly.
- International Competitiveness: High-quality products can open doors to global markets, increasing a company’s competitiveness on an international scale.
- Customer Retention and Loyalty: Satisfied customers are more likely to remain loyal and recommend the brand to others, contributing to long-term business success.
In today’s challenging and dynamic corporate climate, quality control is essential for upholding high standards, reducing risks, and cultivating a competitive advantage. It provides the framework for offering top-notch goods and services and guaranteeing the loyalty and happiness of clients.
Quality Control Roles and Responsibilities
It’s important to recognise that quality control includes a variety of jobs and duties when attempting to define it. It also shouldn’t be confused with quality assurance. Quality control is particularly about the measurement and analytical procedures involved in assessing the quality of the product, whereas quality assurance examines the procedures employed to prevent flaws.
Quality control completes fact-finding procedures and performs analyses using specialised research instruments. The analysis of these measurements in relation to a standard set by the quality management department, business regulations, industry associations, and regulatory agencies is the responsibility of a quality control specialist. Change recommendations will be made by quality control based on this evidence collection.
This plan also makes the differences between quality assurance and quality control clear. A comprehensive approach is taken by quality assurance to stop a product from breaking down. Conversely, quality control makes the ultimate determination as to whether a product is truly defective or not. Both positions fall under the wide category of quality control.
As a result, a quality control employee is responsible for informing important parties and stakeholders of the results. A competent quality control professional may help with problem-solving and spread scientific and research-based thinking throughout the corporate community. These experts are crucial to the design process of a product since they assess whether a company’s development is genuinely suitable for the market.
Quality Control vs Quality Assurance
Although quality assurance and control are commonly used synonymously, there are several important distinctions between the two. Quality control focuses mostly on quality standards, such as making sure an item meets requirements. The culmination of all procedures and activities required to prove that the standards for quality are met is known as quality assurance.
Quality specialists may eventually switch from quality assurance to quality control as a result of this distinction as their careers advance. Quality assurance programmes and departments ensure that products meet all safety and quality laws for the benefit of higher management, consumers, and government inspectors. Quality control is a component of quality assurance.
