Nowadays, we generally expect products and services to function without giving much thought to it. However, in the early part of the 1900s, it was not always easy and guaranteed to expect products to be good. Over time, specialists came up with ways to test and enhance the quality of products. Now, businesses can implement these best practices to have their products good and consistent.
Key Components of Quality Control
• Inspection: Continuous inspection of goods to detect mistakes or issues.
• Testing: Testing to ensure products work correctly.
• Statistical Process Control (SPC): Using numbers and graphs to monitor where the process is at and remain on track.
• Records: Maintaining records of inspections and repairs to monitor progress.
• Resolving Issues: Taking action to resolve issues and not allow them to occur again.
• Training: Demonstrating staff how to provide high quality.
• Continuous Improvement: Always looking for how to improve.
Quality Control and Quality Assurance
Quality control (QC) seeks and fixes errors. Quality assurance (QA) attempts to prevent errors by creating sound processes. Both assist firms in making sure that products are suitable for customer requirements and meet regulations.
How Quality Control Operates
Quality inspections are conducted at every stage—during the production of the product, with the end product, and with the raw material. Testing identifies issues early so they can be repaired promptly.
In other companies, quality checking may involve customer reviews, feedback, and inspection to ensure services are satisfactory.
Quality Control in Various Industries
Quality control is important in every area but seems various depending on the profession:
In production, it is examining materials and products carefully to avoid issues.
• In food, it refers to verifying safety and health regulations.
• In medicine, it means making drugs safe and effective.
• In computer programming, it means to test software to catch bugs before release.
Methods of Quality Verification
Various industries employ various methods of managing quality. For example, medicine and food employ very strict testing because safety is of top priority. Other industries such as education may employ broad methods of ensuring quality.
Some common methods of ensuring quality are:
• Control Charts: Charts that indicate how processes vary over time.
• Process Control: Adjusting and monitoring steps to ensure consistent quality.
• Acceptance Sampling: Sampling test of items to see whether the whole batch is good.
• Process Protocol: Mapping each step to see how well it works.
Who Performs Quality Control?
Some have their own quality control staff. Others outsource groups to inspect products, particularly in the case of foods where safety is so critical.
Why do we require quality control? What are the advantages?
Quality control (QC) is highly significant for numerous reasons. QC benefits both customers and businesses in numerous ways:
• Customer Satisfaction: QC makes sure that products and services are compliant with customers' requirements, thus making them satisfied and loyal.
• Preventing Defects: QC identifies and corrects issues in advance to have less error later on.
• Cost Savings: QC minimizes waste and lowers production costs, thus making operations more efficient.
• Adherence to Rules: QC ensures products comply with laws and regulations to avoid lawsuits.
• Good Reputation: Quality products build a good brand that customers trust.
Quality Control Work and Responsibilities
Quality control includes numerous crucial activities. It is different from quality assurance (QA). QA tries to prevent issues from arising in the first place, while QC tries to inspect products to see if there are any flaws.
Quality Control and Quality Assurance
Quality control and quality assurance are two concepts that sound alike but are not. QC questions whether a product is good. QA ensures the whole process is in place to be high quality.
Individuals working in these positions are able to switch between QC and QA as they proceed in their career. QA departments ensure products comply with all the regulations and safety standards. QC is a subset of QA.
