Quality Assurance Vs Quality Control: What's the Difference?

Before we learn Quality Assurance, let's understand- What is Quality? Quality is extremely hard to define, and it is simply stated: "Fit for use or purpose. What is Assurance? Assurance is nothing but a positive declaration on a product or service, which gives confidence. It is certainty of a product or a service, which it will work well. It provides a guarantee that the product will work without any problems as per the expectations or requirements.

Quality is a relative concept. It is related to certain predetermined characteristics such as shape, dimensions, composition, finish, colour, weight, etc. In simple words, quality is the performance of the product as per the commitment made by the producer to the consumer. There are two main elements in this definition of quality. First, the commitment may be explicit such as a written contract or it may be implied in terms of the expectations of the average consumer of the product.

Quality Assurance is popularly known as QA Testing, is defined as an activity to ensure that an organization is providing the best possible product or service to customers. Quality Control in Software Testing Quality Control in Software Testing is a systematic set of processes used to ensure the quality of software products or services. The main purpose of the quality control process is ensuring that the software product meets the actual requirements by testing and reviewing its functional and non-functional requirements. Quality control is popularly abbreviated as QC. QA aims to prevent the defect QC aims to identify and fix defects It is a method to manage the quality- Verification It is a method to verify the quality-Validation It does not involve executing the program It always involves executing a program It's a Preventive technique It's a Corrective technique It's a Proactive measure It's a Reactive measure It is the procedure to create the deliverables It is the procedure to verify that deliverables QA involves in full software development life cycle QC involves in full software testing life cycle In order to meet the customer requirements, QA defines standards and methodologies QC confirms that the standards are followed while working on the product It is performed before Quality Control It is performed only after QA activity is done It is a Low-Level Activity, it can identify an error and mistakes which QC cannot It is a High-Level Activity, it can identify an error that QA cannot Its main motive is to prevent defects in the system. It is a less time-consuming activity Its main motive is to identify defects or bugs in the system. Quality Assurance provides assurance that quality requested will be achieved whereas Quality Control is a procedure that focuses on fulfilling the quality requested.

Quality ASSURANCE & Quality control

Quality assurance QA is a way of preventing mistakes and defects in manufactured products and avoiding problems when delivering products or services to customers; which ISO defines as "part of quality management focused on providing confidence that quality requirements will be fulfilled". The terms "quality assurance" and "quality control" are often used interchangeably to refer to ways of ensuring the quality of a service or product. DMAIC is a data-driven quality strategy used to improve processes. Quality assurance comprises administrative and procedural activities implemented in a quality system so that requirements and goals for a product, service or activity will be fulfilled. Quality assurance includes two principles: "Fit for purpose" the product should be suitable for the intended purpose ; and "right first time" mistakes should be eliminated. QA includes management of the quality of raw materials, assemblies, products and components, services related to production, and management , production and inspection processes. Historically, defining what suitable product or service quality means has been a more difficult process, determined in many ways, from the subjective user-based approach that contains "the different weights that individuals normally attach to quality characteristics," to the value-based approach which finds consumers linking quality to price and making overall conclusions of quality based on such a relationship.

Quality Assurance is process oriented and focuses on defect prevention , while quality control is product oriented and focuses on defect identification. Share this comparison:.

Every project has a quality control section to take care of these functions. The quality assurance function usually stays with the organization and the quality control section has to communicate with the organization to coordinate between these two processes. Since these processes are connected and work in coordination, many professionals, especially those working in small and medium sized organizations, do not understand their differences. This reminds me of one interaction when I was in my ISO training course a few years back. I met with many professionals involved in quality management.

Здесь, в командном центре, Джабба выше самого Господа Бога, а компьютерные проблемы не считаются со служебной иерархией. - Это не вирус? - с надеждой в голосе воскликнул Бринкерхофф. Джабба презрительно хмыкнул.

 - Она бросила пачку компьютерных распечаток ему на стол. - Я что, бухгалтер. - Нет, милый, ты директорский автопилот.

Ей хотелось поскорее оказаться в Третьем узле, и она достаточно хорошо изучила своего шефа, чтобы знать: Стратмор никуда не уйдет, пока она не разыщет ключ, спрятанный где-то в компьютере Хейла. Ей почти удалось проскользнуть внутрь, и теперь она изо всех сил пыталась удержать стремившиеся захлопнуться створки, но на мгновение выпустила их из рук. Створки стали стремительно сближаться. Стратмор попытался их удержать, но не сумел. За мгновение до того, как они сомкнулись, Сьюзан, потеряв равновесие, упала на пол за дверью. Коммандер, пытаясь приоткрыть дверь, прижал лицо вплотную к узенькой щелке. - Господи Боже мой, Сьюзан, с тобой все в порядке.

Неужели Хейл никогда не слышал о принципе Бергофского. - Вот что нам надо сделать.  - Стратмор начал спокойно излагать свой план.  - Мы сотрем всю переписку Хейла с Танкадо, уничтожим записи о том, что я обошел систему фильтров, все диагнозы Чатрукьяна относительно ТРАНСТЕКСТА, все данные о работе компьютера над Цифровой крепостью, одним словом -. Цифровая крепость исчезнет бесследно.

Он закрыл глаза, и воспоминания хлынули бурным потоком. Он вспомнил факультетские заседания, лекции - все то, что заполняло девяносто процентов его жизни. Вспомнил о Сьюзан.

 Это может быть не вашим делом! - раздался зычный голос у них за спиной. Мидж от неожиданности стукнулась головой о стекло. Бринкерхофф опрокинул директорский стул и бросился к двери. Он сразу же узнал этот голос. - Директор! - воскликнул он и, подойдя к Фонтейну, протянул руку.

Смит потянулся к объективу камеры, чтобы направить его в глубь кузова.
