What Makes Quality Inspection Different from Quality Control?

There are many subtle differences between QI and QC. Although these terms are used mostly in the manufacturing sector, most other businesses also benefit from it.

When items are manufactured, there is a need for quality inspection when the items are completed. The basis for quality inspection include tools, testing, and standards of the most demanding customers. After inspection, QI informs the accountable manager if there is a problem and gives advice on how to solve the issue.

On the other hand, quality control creates products which are subject to QI. In QC, errors, and issues are identified and corrected during the development and manufacturing process. QC will be very successful if the company is focused on providing quality products as their core value and goal.

QI and QC are not simple processes. QI detects problems with the finished product. It is an inspector, a manager, a third-party testing service, or the customers who do QI.

For food processing facilities, for example, poor quality items are not allowed to reach the market so they are set aside by QI. If goods are rejected, then some of them are recycled. Checklists, visual guides, chemical testing, and other tools are used to sort poor quality products from good products quickly.

In QC, poor quality products are prevented from being produced. The work of QC is before inspection which helps to reduce the work of QI. The main focus of QC is to find and fix sources of error, malfunction, or weakness.

When things are corrected at the point of failure by QC, it reduces or eliminated QI and this shows that feedback is king. All process points are inspected by QC so that they can find problems and repair and reconfigure the process. Problems usually lie in the tools, talents, materials, machines, or even the temperature and lighting at the workstation. If there is feedback from QI which is high-volume and high-quality, then QC can perform well.

Before the functions of QC and QI are isolated by most businesses. In order to help make businesses free of error, there is already more interaction and cooperation where QI feed QC with important data.

Before shipment, QI is done. To avoid shipment delays, QI should only be testing a limited amount of products. They say that this is a sample that is statistically-sound. Before delivery they check the samples for workmanship, safety, functionality, and performance. Buyers of these products also help in inspecting deliveries using their own set of standards. This customer feedback helps to improve the management of the supply chain. It is important for business owner to weight the cost of inspection against the value of the goods produced. SafetyChain is a food quality management software that can help businesses manage the costs and the processes.
