Quality control (QC) is a process through which a business seeks to ensure that product quality is maintained or improved.
Quality control involves testing units and determining if they are within the specifications for the final product.
The quality control used in a business is highly dependent on the product or industry, and several techniques exist for measuring quality.
The food industry uses quality control methods to ensure customers do not get sick from their products.
Quality control creates safe measures that can be implemented to make sure deficient or damaged products do not end up with customers.
Quality control involves testing units and determining if they are within the specifications for the final product. The purpose of the testing is to determine any needs for corrective actions in the manufacturing process. Good quality control helps companies meet consumer demands for better products.
The quality control used in a business is highly dependent on the product or industry. For example, in food and drug manufacturing, quality control includes ensuring the product does not make a consumer sick, so the company performs chemical and microbiological testing of samples from the production line.
Quality control and quality assurance are terms often used to define the same thing, but there are distinct differences. Quality control focuses on quality requirements, such as ensuring a part meets specifications. Quality assurance refers to the sum of all actions and processes needed to demonstrate that quality requirements are fulfilled.
What this difference means for quality professionals is that as you move through a quality control career, you might transition from quality control to quality assurance. Quality control is part of quality assurance, which are programs and departments that assure upper-level management, customers, and government inspectors that products meet all quality requirements and safety standards.
Quality control (QC) is a procedure or set of procedures intended to ensure that a manufactured product or performed service adheres to a defined set of quality criteria or meets the requirements of the client or customer. QC is similar to, but not identical with, quality assurance (QA). While QA refers to the confirmation that specified requirements have been met by a product or service, QC refers to the actual inspection of these elements.
A quality plan is a document, or several documents, that together specify quality standards, practices, resources, specifications, and the sequence of activities relevant to a particular product, service, project, or contract. Quality plans should define:
Objectives to be attained (for example, characteristics or specifications, uniformity, effectiveness, aesthetics, cycle time, cost, natural resources, utilization, yield, dependability, and so on)
Steps in the processes that constitute the operating practice or procedures of the organization
Allocation of responsibilities, authority, and resources during the different phases of the process or project
Specific documented standards, practices, procedures, and instructions to be applied
Suitable testing, inspection, examination, and audit programs at appropriate stages
A documented procedure for changes and modifications to a quality plan as a process is improved
A method for measuring the achievement of the quality objectives
Other actions necessary to meet the objectives.
