Quality control is a set of processes and techniques used to ensure that products or services meet established quality standards and requirements. It is a systematic approach that seeks to identify and correct any deviations or defects in a product or service before it reaches customers or end users. It involves a series of activities that are carried out throughout the entire life cycle of a product or service, from conception and design, to production, distribution, and use of the product or service. These activities may include inspection, testing, sampling, audits, process monitoring, data analysis, customer feedback, among others.

The objective of these processes is to ensure that products or services are consistent in terms of quality, reliability, performance and compliance with requirements. This helps prevent defects or problems from appearing in products or services delivered to customers, which can have a negative impact on customer satisfaction, company reputation, and costs associated with repairing or returning products. defective.

Quality control can be carried out by internal company personnel, as well as by third parties, such as certification bodies or external clients. It may also be supported by internationally recognized quality standards or norms, such as ISO 9001, which provide a framework for establishing an effective quality management system.

Compliance with standards and requirements: Ensures that work is carried out in accordance with the standards, regulations and legal requirements established by local, regional or national authorities.

This helps prevent the appearance of defects or problems in the work, which can affect its durability, function and appearance.

This helps avoid costly corrections or repairs later, and ensures that work is done correctly from the beginning, minimizing the risk of errors or failures on the job.
