Ensuring High Quality Standard Is Present In Products And Goods
Quality control is a procedure used to ensure that a top notch standard exists in merchandise or goods. Quality control may include actions and processes as seen fit by the company in verifying and overseeing certain qualities in a product or service.
A product or service needs to be evaluated by the quality control officers for flaws with the objective of detecting those that fail to fulfill the company standards. In the case a defect is found, the quality control officer or team may need to halt production in a bid to trace the source of the malfunction. Quality control officers or teams aren't served with the liability of resolving issues with services or products quality. Technical personnel or consultants are charged with solving quality difficulties.
Quality control is not limited to services and products in a business. Additionally, it evaluates the level of knowledge in staff. When an employee is inadequately trained to handle the responsibility he's charged with, quality or work will be low and affect output. Quality control should not be mistaken for Quality assurance, although the two are comparable. Quality control is product based, while Quality assurance is Process oriented.
When it comes to controlling the Quality of goods and services in a company, various tools are employed. There are seven basic tools used in quality control. These tools are graphical techniques used to evaluate and analyze statistical data and measure variance. The basic Quality Control tools are;
The cause and effect diagram or the Ishikawa or Fish bone chart- identifies the cause of a quality issue and attempts to find a solution by categorizing causes with the aim of discovering variation.
The Check Sheet is a straightforward document utilized in the range of data in real time at the location the data is being produced. The document is a bare form used to record either qualitative or quantitative data.
Control Charts, Shewhart or process - behaviour charts are statistical tools used to determine variance using graphs. Histograms are common graphs that are easy to understand, they show frequency distribution.
The Scatter Diagram shows pairs of numerical data, one variable on each axis in order to establish a relationship.
The Pareto Chart exhibits the key components on a bar chart.
Stratification is a tool that separates data collected from different sources and shows them as patterns.
For any company to be a success, the customer needs to be satisfied with the quality of service which is rendered. Quality control measures and teams must be set in place by the company's management. When a company has a bad quality control record on a contract, the chance of renewing that contract is small and clients will likely be hesitant in working with the company on future projects.
