What is Quality Assurance(QA)? Process, Methods, Examples

The terms quality assurance, quality control and quality management are usually used interchangeably. As a test manager or project manager, it is important to understand the differences between these terminologies so that you know what exactly are you talking about with your client and team members.

Quality Assurance is the set of activities that determine the procedures and standards to develop a product. Quality Control refers to the activities and techniques to verify that the developed product is in conformance with the requirements. The ultimate output of both processes is to deliver a quality product.

Are you also confused with quality assurance vs quality control in software testing? No problem! Keep reading to know the difference. Quality Management is a much broader field that ensures the required level of quality is achieved in software product. You can create a standard quality management approach for your organization.

It has four main sub processes: quality assurance, quality planning, quality control and quality improvement. Software Quality Assurance , QA , is a planned and systematic way of creating an environment to assure that the software product being developed meets the quality requirements. QA refers to the implementation of well-defined standard practices and methods.

It is a pro-active quality process. This process is controlled and determined at managerial level. Quality assurance focuses on the process checklists, process standards, project audits, methodology and procedures for development. It is a preventive process that aims at establishing the correct methodology and standards to provide a quality conducive environment to the product being developed.

In this sub process, quality assurance plan is created for a particular project. In the quality assurance plan, organizational standards are selected which are applicable to a project. It should also involve the plan for quality control. Quality assurance planning details out what QC activities are performed, when the QC activities are performed and who will perform those.

It also contains details of resource required, tools and techniques to be used for performing quality control. Quality Control, QC, is the set of activities that control the quality of product being developed by identifying any bugs that might be present. Quality control process is a subset that falls under the quality assurance. It is a corrective process. The task of actual testing is performed to find out and identify the bugs present in the product.

The bugs are raised to the developers, who then try to fix them. After fixes, the product is verified again such that the functionalities and features are working as required.

QC process assures that that the product being developed is of the required quality. Examples of quality control activities include inspection, deliverable peer reviews and the software testing process. Quality improvement is a formal approach to analyse the feedback received from the quality control team. In this process efforts are put systematically to identify any room of improvements in the existing standards and procedures.

The target is to improve the process that establish the standards of quality in the organization. Quality control activities are performed after the software has been developed. We have listed down the differences between quality assurance and quality control to further clarify your concept:.

It is critical that the organizational standards are defined by experts as it will lay the foundation of quality assurance and assures development of reliable, quality products.

The standard is harmonized with the software life cycle process and contains requirements for initiating, planning, controlling and executing the Software Quality Assurance. Quality audit is a quality assurance technique that examines the work products and evaluate whether the software product has followed the standards, guidelines, regulations, plans and procedures.

It a systematic approach to examine all the required procedures and standards were considered at the time of product development and testing. The following tools are indispensable while you are setting up the quality assurance process for your organization:.

Cost benefit analysis is a systematic approach of evaluating an investment against its expected benefits.

It is used to determine whether the investment is feasible in terms of labour, time and cost savings. This technique uses brainstorming with mind mapping on a diagram and compels you to think of all the possible causes to a problem. Once you have identified the root cause, you will be able to find the right solution for it. Control charts are used to analyse performance trends of process over time. It is an important tool to determine if you need to make any fundamental changes to the process and avoid specific problems.

There can be two types of cost of quality. The cost of poor quality affects the internal and external costs resulting from failing to meet requirements. On the other hand, the cost of good quality includes the prevention costs for investing in services and appraisal of product. It is systematic approach carried under controlled conditions to determine the relationship between factors affecting a process and the output of the process.

It is used to manage process in order to analyse which input has the significant impact and what steps can be taken to optimize the output. A quality culture should be established where everyone feels responsible for maintaining the quality of product. One of the popular techniques for quality control is the Quality Reviews. According to Wikipedia, a software review can be defined as:. The product to be reviewed is an outcome of any software development activity.

Quality reviews are conducted to review the project plans, requirements documents, design documents, quality assurance plan, test documents and code. The people reviewing the software products give their feedback which is recorded and passed to the concerned person for incorporating the changes.

Management reviews are conducted by the upper management to see the amount of work done and take required decisions accordingly. Technical reviews are a less formal type of quality control review, which is led by trained moderators. Technical reviews are conducted to establish consistency in the use of technical concepts. It is conducted at an early stage to verify that the technical standards and practices are used correctly. Any alternatives options for the product are also evaluated in the technical quality control review.

A walk-through is a type of quality control review in which the author of product leads the review session and presents his thought process to the entire team. The product to be reviewed is thoroughly explained and the feedback is gathered from the audience. Walk-throughs are usually conducted for the high level documents such as specifications documents, design documents.

Walk-throughs are useful especially if the audience is people who do not understand the software easily. Inspection is a formal review practice found in software testing practices to identify defects and issues. It is a planned meeting in which roles are defined to each participant.

Inspection is a quality control process to check whether the software product is in compliance with the required specifications and standards. Defects are logged if any non-compliance is found. The main target of inspection is to find defects as early as possible. An estimate of re-work effort is also taken as the output of this QC process. Inspection is conducted for design documents, specification documents, test documents and the code.

Software testing techniques are a major tool of the quality control process. There are several software testing techniques such as functional testing, black box testing, usability testing, exploratory testing, compatibility testing, regression testing. Quality assurance is the implementation of standardized procedures whereas quality control is following those procedures and techniques to assure the deliverable is of required quality. The processes of quality assurance, quality planning, quality control and quality improvement make up the bigger process of Quality Management.

Software quality engineering SQE is the process of implementing quality checks throughout the entire development cycle. SQE plays a key role in ensuring fast-paced agile and DevOps teams produce high-quality software. When software quality engineering is integrated into workflows, it can improve agility, productivity, and ROI. Quality engineering QE is a process that applies rigorous quality checks to each stage of product development. It does this through analysis, development, management, and maintenance of quality assurance QA protocols. QA is often continued after a product has been delivered.

Software quality is defined as a field of study and practice that describes the desirable attributes of software products. There are two main approaches to software quality: defect management and quality attributes. A software defect can be regarded as any failure to address end-user requirements. Common defects include missed or misunderstood requirements and errors in design, functional logic, data relationships, process timing, validity checking, and coding errors. The software defect management approach is based on counting and managing defects.
