As the name implies, software quality assurance is a procedure or a role played by a software engineer to ensure that the software program meets the customer’s requirements without making any concessions or slippages. The four steps of Software Quality Assurance are Plan, Do, Check, and Act.

The procedures necessary to preserve the application standard’s high quality are referred to as “with Plan.” Do not forget to mention the development process, including the build and testing phases. Check refers to the observation and assessment of the implementation routes, while Act relates to the activities required to keep the application in good working order.

Components of SQA system:

There are six different types of SQA components:

Components of the Pre-Project

It ensures that the project’s commitment has been properly defined in terms of time estimation, clarity of client needs, total project budget, risk appraisal, and total workforce required for that specific project. It also ensures that quality and development plans have been clearly stated.

Components of the Software Project Life Cycle

The review, expert opinions, software testing, and software maintenance components are all included in this component. It contains elements like reviews, expert opinions, and finding software design and programming defects in the project development life cycle. In contrast, it specializes in maintenance components and development life cycle components to enhance maintenance tasks in the software maintenance life cycle.

Components of Infrastructure for Error Prevention and Improvement

Based on the organization’s cumulative SQA experience, this component includes staff training, certification, configuration management, preventive and corrective procedures, and preventive and corrective actions to reduce the rate of software faults.

SQA Components in Management

This lesson covers software quality measures, software quality expenses, maintenance, and development activity control, and the introduction of managerial engagement to lower the project’s risk of quality, schedule, and budget.

Standardization, Certification, and SQA System Assessment Components

The primary goal is to apply worldwide professional knowledge to aid in coordinating various organization quality systems on a professional level.

Getting Ready for SQA Human Components

Managers, testers, and other SQA practitioners interested in SQA make up this group. The major goal is to assist launch SQA operations, identify gaps and deviations, and offer changes.

SQA Techniques:

There are numerous methods for SQA. The following are a few of them:


Both internal and external stakeholders are conducted to assess the entire project. The reviewer analyses the whole software and determines if it is a testing, development, requirement, or design issue if an issue is discovered. The main goal is to assess software quality and decide whether or not it meets or exceeds customer expectations.

Performing an audit:

Stakeholders inspect the entire work product and all data during auditing to see if it follows the established processes or not.

Testing of Functionality:

The functionality of the entire software is tested in functional testing to see if it is working as planned. It examines “how the system functions” without knowing “what the system functions.” It’s similar to black-box testing, in which the user knows what the desired outcome is but not how it’s generated.


It ensures that everything in the program is standardized, i.e., it adheres to all standards in documentation, development, and quality assurance. It decreases uncertainty and thereby enhances program quality.

Inspection of the Code:

Code Inspection is one of the formal types of review to identify errors in the code and highlight any concerns. It is guided by a professional Moderator rather than the code’s author. There are suitable entry and exit criteria in place for the meeting. Users must prepare thoroughly before the meeting to understand all papers and issues before addressing their concerns.


A software walkthrough is an informal process where the author reads the document or code and the peer members write down their recommendations or errors and submit them. It is not documented like inspection, and the meeting does not require a moderator. Instead, its major goal is to find out how far the code has progressed and solicit feedback from peers to improve software quality.

Stress Analysis:

Stress testing is used to see how well a system performs under high load. This testing is vital for software quality since stress and load testing are done adequately in e-commerce apps to test the software’s capabilities (how many maximum numbers of users can access an application at a time).

Inspection of the Design:

The purpose of design inspection is to check different aspects of software using a checklist, such as functional and interface design, conventions, general requirements and design, requirement traceability, logic, coupling, and cohesion.

Elements of Software Quality Assurance:

  • Standards for software engineering
  • Technical audits and reviews
  • Testing software for quality assurance
  • Error analysis and collecting
  • Change management is used to describe the process.
  • Programs for education
  • Management of vendors
  • Management of security
  • Safety
  • Management of risks

SQA Tools:

A variety of QA tools can aid software quality assurance. For different goals, different QA tools are necessary. The following category of QA tools, commonly known as QA software, is required for thorough software quality assurance.

  • Infrastructure

 Management of Releases

 Controlling the source

  • Review of the Code

Automated Code Inspection

             Code Review by Peers

  • Examining (QA software)

Management of Tests

Tracking of Bugs and Issues

Browser, device, and operating system testing

Testing for Usability

Testing Under Load

Continuous Integration and Automated Testing

  • Analytics & Monitoring

Monitoring of Availability

Business Intelligence

Handling Exceptions

Monitoring of Logs

Monitoring of Results

Monitoring and testing for security

  • Customer Service

Advantages of SQA:

Client Confidence Is Boosted:

Proper quality control at various levels of software, such as review, inspection, and auditing, increases client confidence in the submission of weekly defects. In addition, requirement metrics help to assure the client that the work is being completed on time, with the participation of both internal and external stakeholders.

SQA helps save money:

Defects discovered early in the process, whether in requirement gathering, code, or testing, are simple and cost-effective to fix. Proper SQA performed at several levels helps reduce those risks by identifying and resolving the majority of defects early on, saving money on setting faulty software after it has been presented to the client, which can cost the company’s reputation, users, and clients.

Customer Satisfaction increased is a must-do for any business:

In addition, it ensures that high-quality software is built by the requirements, and it also provides that recommendations are taken into account.

Productivity and efficiency are boosted:

When development and testing are done concurrently, problems detected soon after a single module are completed and fixed by developers quickly allow everyone to work in peace and be more productive rather than being plagued with multiple issues once the software is finished.

Prevents Unexpected Emergencies:

The stakes are likewise very high when designing enterprise software. Because the software handles many sensitive data from customers, it must function as intended with no outages, corruption, or communication breakdowns. Therefore, SQA should thoroughly test the software to ensure it performs as planned.


SQA is an umbrella activity that encompasses the entire project from requirement collecting to project maintenance throughout the software lifecycle. It includes all activities and processes carried out at various stages of software development to ensure that the software provided is of high quality and low risk, allowing it to prosper in the market and needs of customers and clients.


What are quality assurance techniques?

Quality assurance (QA) is a method of preventing errors and faults in manufactured items and problems when delivering services or products to clients, defined by ISO 9000 as “a component of quality management aimed at ensuring that quality criteria are met.”

What are software engineering SQA techniques?

Software Quality Assurance (SQA) monitors software engineering methods and processes to ensure published software quality. SQA encompasses the software development lifecycle’s requirements management, software design, coding, testing, and release management phases.

What are SQA and SQA activities?

Software Quality Assurance (SQA) is a set of actions that ensures software engineering processes are of high quality. In addition, it ensures that generated software satisfies and adheres to quality requirements that have been set or standardized.
