Quality Control Plan:
A quality control plan is a formal document with supporting information that shows a process owner and local work team the important variables, that impact a process workflow relative to its outputs. In this article I will discuss about quality control, quality assurance and quality control pan in garment industry.
Quality control and quality assurance are complex areas of the apparel industry. First off, quality assurance is not quality control, but quality control is an aspect of quality assurance. Quality assurance is the process of designing, producing, evaluating, and assessing products to determine that they meet the desired quality level for a company’s target market. Quality control is the day-to-day implementation of quality assurance, and to succeed you have to be very proactive at all levels.
Quality control, is different from quality assurance. The objective of quality control is to check if the products being produced are according to the given specifications. Their entire job is during the production process. Quality control department has quality inspectors / auditors who check the product specifications at different stages of production. In most of the industries, the quality control teams are divided into two parts. First team is responsible for inline quality inspection. Inline quality inspection means that the quality inspectors check the products at different machines randomly. The second team is responsible for final inspection. Final inspection means that the inspection of goods at the end of production line. The amount of inspection varies from industry to industry.
Quality assurance looks at a product from the first design concept until it is sold to the consumer. Quality control is generally understood as assessing for quality after products have already been manufactured and sorted into acceptable and unacceptable categories. It is costly for companies that do not take a quality assurance method, but only look at quality in terms of quality control. Quality is a multifaceted concept that describes how well a service, process, material, or product possesses desired intangible or physical attributes.
Garment manufacturing companies always strive to produce garments that meet their customer requirements. A wide range of quality processes, are used in the apparel industry to ensure that these quality standards are met. The examination and measurement of garments are common ways of ensuring that the garments produced meet customer specifications. Quality control consists of a 100% inspection process, to ensure that garments not satisfying customer requirements are removed. A strong quality control plan or QC plan helps to set quality targets for apparel manufacturing to ensure that the deliverables produced, meet the needs of customer requirements.
Quality Control Plan in Garment Industry:
A Quality Control Plan, or QC Plan, is a critically important document for apparel business. It is the basis for assessing and maintaining of the qualÂity of continuous emission monitoring data. In this article I have discussed a quality control plan or QC plan with template. In quality control plan template I have given a readymade garment factory as an example.
