Verifying And Monitoring Characteristics In Your Products And Services
Quality control is a process used to make certain that a high quality
standard exists in merchandise or goods. Quality control might involve
actions and procedures as seen fit by the company in validating and
monitoring certain characteristics in a service or product.
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 products and services in a company. It also analyzes the level of competence in employees. When an employee is inadequately trained to handle the responsibility he is charged with, quality or work will be low and affect output. Quality control should not be confused with Quality assurance, although the two are similar. Quality control is product based, while Quality assurance is Process oriented.
When it comes to managing the Quality of products and services in a business, a variety of tools are applied. There are seven basic instruments used in quality control. These tools are graphical techniques utilized to review and analyze statistical data and measure variance. The standard Quality Control instruments are;
The cause and effect diagram or the Ishikawa or Fish bone chart identifies the causes of a quality problem and tries to find a solution by categorizing causes with the aim of finding 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 - behavior charts are statistical instruments utilized 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 successful, the customer has to be satisfied with the quality of service that is rendered. Quality control measures and teams have to be set in place by the company's management. When a company has a poor quality control record on a contract, the chance of renewing that contract is slim and clients will be hesitant in working with the company on future projects.
