A Brief Insight into the Quality Control process

Quality control (QC) is a modern-day process that businesses utilize to ensure that a service or product adheres to a predetermined set of quality standards. Also, companies use this procedure to ensure their offerings meet the needs of their customers perfectly. Quality control usually involves building an environment where the management and employees are constantly striving for perfection and improvement. It needs extensive training, developing benchmarks for assessing service or product quality, and evaluations to check for any variations in quality.

4 Steps In The Quality Control Process

Setting Testing Standards

To incorporate a quality control program, first determine what standard you wish to meet. After this, decide the extent of actions you want to take. For instance, the quality control team must determine the number of samples to be taken for testing, how their selection will happen, and what the testing process will be.

Inspecting Raw Materials And Different Stages

Quality control involves examining every step of an organization’s production process. The team members may start by assessing the raw materials that are utilized to develop a product and then testing at numerous phases within the production process. The experts aim to recognize where any issues are occurring.

Resolving Problems

The quality control specialists fix the issues and prevent them from recurring in the future. The exact methods that a firm uses depend on the products and industry. For instance, in food production, the quality control team carries out microbiological testing to ensure that the finished items do not make customers sick. Also, they perform quality control in the packaging stage to ensure that the food stays intact before the expiry date. However, in the automobile production industry, quality control may focus on skid and collision tests.

Data Collection And Decisions

After identifying the issues, the quality control experts collect real-world data and deliver the reports to the management. Eventually, corrective action is taken. For instance, the organization may repair the remaining faulty production units or remove them altogether to invest in different technology.

If a lot of products are found defective, the firm must devise a viable plan to improve the manufacturing procedure. If the issue lies with the supplies being used, the enterprise must buy better quality raw materials next time. The quality control process must be ongoing to look for new signs of problems.

The Different Quality Control Methods

X Bar Chart

To create this, select products randomly and understand the extent to which each item has varied from an ideal standard for a given trait. In an x bar chart, plot the degree of variance on the y-axis and the sample numbers on the x-axis. By examining the x bar chart graph, you can understand whether faulty pieces appear randomly or due to systemic errors.

For instance, test 10 randomly selected items, and you may find that one of them is faulty. On doing the same with 100 units, you may learn that 10 are defective. It shows there is something wrong with your manufacturing system and can produce a defective piece.

Six Sigma

It is a quality control technique that assures the biggest success rate. Quality control experts who practice this help firms locate and remove defects in their manufacturing mechanisms and business procedures. In this case, there will be no quality concerns or systematic errors afterward.

100% Assessment Mode

It is labor and time-intensive as it demands a firm to examine a single product thoroughly for quality. Experts in charge of luxury items like jewelry and super-cars usually employ this quality control method. It is very hard to implement in industries that produce goods in bulk.

Taguchi Method

This quality control technique prioritizes research, development, and design. Its philosophy is that any potential for variance in an item can be removed by incorporating some calculated changes in its design. In this case, you need to think about potential areas of defects or variance. Then, remove them at the design stage, so they do not cause problems later.

Quality Control Vs. Quality Assurance

Quality assurance provides confidence that the firm’s quality needs will be fulfilled. However, quality control is the testing aspect of quality management. It refers to the activities and techniques utilized to meet the quality requirements.

Quality control is a very effective process that will help you satisfy your customers to the fullest. Get in touch with the reputed names in this field, and they will support your business activities strongly.
