Different quality control processes eliminate the possibility of releasing defective products in the marketplace.
All the goods and materials that we buy everywhere have undergone specific production processes. These products that are available in the market have passed every manufacturing procedures quality control process. Companies hire analysts and use quality control tools to ensure top-notch quality.
From a business perspective, creating quality products that meets your customers wants and needs helps you obtain loyal customers. More so, being able to produce first-rate products helps you generate more sales.
What is quality control?
Quality control is a critical part of a production process. It involves examining and testing products to ensure they are within the overall quality standards. Through this process, it helps create a type of work culture wherein part of the objectives for both the management and staff is to strive for excellence.
Importance of quality control
Different quality control processes eliminate the possibility of releasing defective products in the marketplace. In addition, it promotes quality consciousness in the workforce, and it also helps reduce production costs.
Being able to produce high quality products strengthens every organization’s brand. Having a positive reputation can easily elevate market revenue. Consumers benefit from the quality products, which will result in them becoming repeat customers. This then boosts the company’s profits.
List of quality control tools
Of course this process will not be successful without the use of quality control tools. These tools help companies monitor and manage their quality control initiatives.
Quality control analysts use the following quality control tools in a variety of ways, such as data analysis and problem solving:
Pareto chart
Pareto chart is a bar graph providing data from the largest number of frequencies to the smallest. One example of this is a bar graph that shows the highest number of categories of products with deficiencies. From these, quality control analysts will know which categories need to be prioritized in terms of improvement processes.
Flow chart
Flow chart is commonly used in reporting, specifically in organizational structures. However, QC analysts use flow charts to document workflow processes. In terms of quality control, they utilize flow charts to identify where the bottlenecks or breakdowns are in the work process. Recording the steps in each process via flow chart shows a depiction of what the process looks like. This helps determine certain issues within the process.
QC analysts also use flow charts to show certain changes in the overall processes.
Scatter diagram
Scatter diagram showcases the relationships between specific variables. These variables represent cause and effect relationships, with results illustrated in a cartesian plane.
Histogram
Histogram involves patterns of data that are categorized in different process conditions. It should have a minimum of 50-75 gathered data points to make sure that all gathered data points are enough. From there, QC analysts will detect and evaluate patterns that can help them have a better understanding of certain production variations.
Check sheet
A check sheet is used to collect different types of data, like the number of times a specific incident has already occurred. Check sheets help certain departments to implement solutions wherein these incidents will be avoided.
