What is QA in Software Development?

If you are running a software development company, then you must know the importance of software testing and software quality assurance. QA (Quality Assurance) plays a significant role during software creation. QA in software cannot be compared with any other processes. 

Quality Assurance is all about focusing on determining and preserving defined requirements for developing trustworthy products and services. A well-equipped QA practice enhances organizations' goodwill and encourages customer satisfaction, makes workflow efficiency better, and gives a real-time competitive advantage.

The driving force behind the QA in software procedure and process is the ISO (International Organization for Standardization). QA is often conjoined with the ISO 9000 international standard. Various companies take advantage of ISO 9000 to make sure that their QA system is in its position and active.

Software Quality Assurance (SQA) has become more significant for developers as a form of keeping away from the errors before they happen, saving time and cost. Sometimes an update or upgrade of a software application can damage various other functions and trigger problems, even after the SQA process in its position.

What are QA Standards? And who Uses

Basically, testers and QA professionals employ these standards in their day-to-day work. Not only the testers and QA professionals who benefit from quality assurance but also others like software developers and other stakeholders also use to monitor the product quality trends to develop over time gradually.

And it is especially true for applications that develop and become progressively advanced - where the QA process also becomes complex. That is why it is crucial for teams to be reflexive regarding their QA process and discover tools that deal with their requirements completely.

The following professionals are engaged in the process of QA testing: 

  • Software tester.
  • Software developer.
  • Project manager.
  • Product owner.
  • End-user.

The Importance of Quality Assurance

The main objective of quality assurance is to deliver a product or service that invariably keeps up a superior quality. It is a dynamic approach where faults are figured out before the product launch. It is also called a pre-quality check.

Reasons for why Quality Assurance is So Important

No matter how big the product you manufactured or software you built, no use if you didn't maintain quality for the product. Quality is the thing that really matters. Quality assurance is an effective method that works as planned. Here are several reasons to know why QA is so important.

Saves Money

A defective and unsecured application costs a lot of money to users. For that, you have to pay for their loss, even most of the time lose their trust. With a systematic approach to QA testing, you can discover all the defects and bugs that may happen in the future. 

Enhances User Satisfaction

Ultimately, users want nothing more than a good experience. If your software application is sluggish or continuously revealing errors, this may lead to your users jumping to your competitors’ products. QA support to develop software applications that is user-friendly, secure, and reliable. 

Improves Customer Satisfaction

Quality assurance can also increase customer satisfaction, therefore, strengthen the goodwill of the organization through word of mouth, and satisfied customers will recommend the product, service, or software to their friends and relatives, and colleagues. This helps to bring more profits to the business.

Promotes Efficiency and Productivity

A glitch in software applications downsizes productivity. When the functioning of the software goes smoothly no doubt, everybody wants to work to bring higher results. An organized QA process from the initial stage of the project will allow the business to run efficiently and more productively.

How Quality Assurance Works

Quality Assurance is a method meant to present to business management and to the public that a service or product depends on requirements of high quality, established by the market or regulatory authorities. It's in some cases called quality control, although quality control has more to finish with the item after it is manufactured. Quality control ended up being prevalent in production in the 1920s as a method to specify and manage the high quality of products. In the 1950s, quality control ended up being essential in public health and public safety.

Quality assurance measures the principles that enter into a service or product previously it heads out to the general public. Quality control utilizes auditors, in some cases individual and in some cases in-house, to assess the techniques that move into product making and delivering services. When an organization has a high-quality assurance team that allows business administration, clients, regulatory and government authorities to understand that a product and services satisfy high-quality demands.

Quality Assurance Methods

Failure Testing: This constantly examines a product or a service to find out if it damages or flops (stops working). For physical products that have to endure stress, this might include testing the product under heat, pressure, or resonance. For software, failing testing may include putting the software application under high usage.

Statistical Process Control (SPC): A approach based upon target data and evaluation and designed by Walter Shewhart at Western Electrical Company and Bell Telephone Laboratories in the 1920s and 1930s. This approach utilizes analytical techniques to manage and control the manufacturing of products.

Total Quality Management (TQM): It is an organization-wide method of continuously improving the quality of all organizational processes. TQM underlying facts, data and analysis to encourage product planning and performance reviews.

Pros and Cons of QA


  • Improves product quality

It is performed after QA is done

The statistical approach applied on QA is known as SPC  or Statistical Process Control

The statistical approach applied to QC is known as  SQC or Statistical Quality Control

QA standards and approaches implemented in order to fulfill the customer requirements. 

QC ensures that the standards are pursued while working on the product.

Why QA Is a Good Career Choice

In this digital era, all the businesses are migrating online to deliver their services and to stand online.
