Who is quality assurance




















Likewise, if we only focus on QC then we are simply conducting tests without any clear vision for making our tests repeatable, for understanding and eliminating problems in testing, and for generally driving improvement into the means we use to deliver our ICT solutions.

In either case, the delivered solution is unlikely to meet the customer expectation or satisfy the business needs that gave rise to the project in the first place. A good point of reference for understanding the difference is the ISO family of standards.

These standards relate to quality management systems and are designed to help organisations meet the needs of customers and other stakeholders. In terms of this standard, a quality management system is comprised of quality planning and quality improvement activities, the establishment of a set of quality policies and objectives that will act as guidelines within an organisation, and QA and QC.

In the ISO standard, clause 3. NASA, one of the most rigorous software engineering firms in the world, provides the following definitions www. Software Quality Control: "The function of software quality that checks that the project follows its standards, processes, and procedures, and that the project produces the required internal and external deliverable products" Software Quality Assurance: "The function of software quality that assures that the standards, processes, and procedures are appropriate for the project and are correctly implemented" Simply put, Quality Assurance focuses on the process of quality, while Quality Control focuses on the quality of output.

QA is focused on planning, documenting and agreeing on a set of guidelines that are necessary to assure quality. QA planning is undertaken at the beginning of a project, and draws on both software specifications and industry or company standards.

The typical outcomes of the QA planning activities are quality plans, inspection and test plans, the selection of defect tracking tools and the training of people in the selected methods and processes.

The purpose of QA is to prevent defects from entering into the solution in the first place. In other words, QA is a pro-active management practice that is used to assure a stated level of quality for an IT initiative.

Undertaking QA at the beginning of a project is a key tool to mitigate the risks that have been identified during the specification phases. Communication plays a pivotal role in managing project risk, and is crucial for realising effective QA. Part of any risk mitigation strategy is the clear communication of both the risks, and their associated remedies to the team or teams involved in the project.

Quality Control, on the other hand, includes all activities that are designed to determine the level of quality of the delivered ICT solutions. QC is a reactive means by which quality is gauged and monitored , and QC includes all operational techniques and activities used to fulfil requirements for quality. QC involves verification of output conformance to desired quality levels.

This means that the ICT solution is checked against customer requirements, with various checks being conducted at planned points in the development lifecycle.

Inspection is the process of measuring, examining, and testing to gauge one or more characteristics of a product or service and the comparison of these with specified requirements to determine conformity. Products, processes, and various other results can be inspected to make sure that the object coming off a production line, or the service being provided, is correct and meets specifications. Auditing is part of the quality assurance function. It is important to ensure quality because it is used to compare actual conditions with requirements and to report those results to management.

An audit should be involved with the evaluation of the process and controls covering the production and verification activities. Formal management systems have evolved to direct and control organizations.

There are quality management systems QMSs as well as environmental or other management systems, and each of these systems may be audited. Quality has been defined as fitness for use, conformance to requirements, and the pursuit of excellence. Even though the concept of quality has existed from early times, the study and definition of quality have been given prominence only in the last century.

Following the Industrial Revolution and the rise of mass production, it became important to better define and control the quality of products. Originally, the goal of quality was to ensure that engineering requirements were met in final products. Later, as manufacturing processes became more complex, quality developed into a discipline for controlling process variation as a means of producing quality products. The quality profession expanded to include the quality assurance and quality audit functions.

The drivers of independent verification of quality were primarily industries in which public health and safety were paramount. You can also search articles , case studies , and publications for quality assurance and quality control resources. It is based on the process maturity framework and used as a general aid in business processes in the Software Industry.

This model is highly regarded and widely used in Software Development Organizations. CMMI has 5 levels. This model assesses the maturity of processes in a Testing Environment. Even this model has 5 levels, defined below-. Quality Assurance is to check whether the product developed is fit for use.

For that, Organization should have processes and standards to be followed which need to be improved on a periodic basis. Skip to content. Quality Assurance in Software Testing Quality Assurance in Software Testing is defined as a procedure to ensure the quality of software products or services provided to the customers by an organization.
