Although QI and QC are two different processes, they are very subtle differences. These processes do not only benefit the marketing sector but it also benefits other sectors.
At the end of the manufacturing process, quality inspection is performed. The basis for quality inspection include tools, testing, and standards of the most demanding customers. QI identifies issues with products which they report to the accountable managers so that they can advise them 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. A company with core value and goal of producing quality products, then there will be a great success with QC.
QI and QC are not simple processes. There is inspection of the finished product in QI. It is possible to do QI if you are an inspector, a manager, a third-party testing services, or even customers do this.
QI sets aside products that are of poor quality so it does not reach the market; this is an example in food processing facilities. Some recycle these rejected goods. In order to hasten the process of sorting out quality products, checklists, visual guides, chemical testing, and other tools are used.
In QC, if products are wrong during the process, then they are take out. Before inspection, QC makes sure that only good products reach QI. QC fixes sources of error, malfunction, or weakness.
Feeback is very important and so QI can be eliminated by correcting things at the point of failure. All process points are inspected by QC so that they can find problems and repair and reconfigure the process. Tools, talent, materials, machines, or even temperature and lighting at the work station are the sources of problems. In order for QC to perform well, there needs to be high-volume and high-quality feedback from QI.
Most business used to isolate the QC and QI functions. Today, however, there is more interaction and cooperation where QI feeds QC with the important data that will help make the business free of error.
QI is done before shipment. Shipment delays can be reduced if QI will only test a segment of the produced products. They say that this is a sample that is statistically-sound. This sample is checked for workmanship, safety, functionality, and performance before delivery. Buyers of these products also help in inspecting deliveries using their own set of standards. When there is customer feedback, there is an improvement of the supply chain. Business owners must weigh the cost of inspection against the value of the produced well. Take SafetyChain, this food quality management software will manage the costs as well as the process.
