Role of Quality Assurance in Software Development

 

 

Quality Assurance (QA) is the method of assessing a system by following specific procedures across the system to ensure that the desired level of quality is attained. Quality Assurance assists the software development team in identifying potential problems through extensive testing, ensuring a high-quality result for the end-user.

 

A software quality analyst is someone who is responsible for implementing quality assurance concepts and techniques across the project lifecycle.

 

QA is an important element of the software development process since it tests and evaluates the program's quality in order to decrease the chance of software failure while in use.

 

Quality Assurance and its importance in software development.

 What exactly is quality assurance? It's a method for establishing and managing a set of requirements for the development of trustworthy goods. A well-designed quality assurance system raises a company's reputation, increases consumer trust in goods, improves workforce productivity, and provides a significant competitive edge.

 

The International Organization for Standardization (ISO) is the motivating force behind QA in application development methods and processes around the world. As a result, quality assurance is frequently associated with the ISO 9000 international standard, which businesses employ to verify that their quality assurance system is adequate.

 

Quality assurance as a structured process has its origins in the manufacturing sector, but it has since extended to a variety of other sectors, including IT.

 

What is the difference between quality assurance and quality control?

 

These two tasks are widely misunderstood. They're not the same in reality. While quality assurance is concerned with preventative measures, quality control is concerned with remedial procedures. Everyone participating in the process is responsible for quality assurance, and quality control is the duty of a dedicated team (of testers).

Nonetheless, all of these tasks are intricately linked. The term "quality control" refers to a subset of the term "quality assurance." Similarly, software testing comes as a subset of quality control.

 

Why is it so critical to maintain software quality?

 

Every software development process must include quality assurance. In general, quality assurance in software development aids organizations in developing products and services that satisfy clients' expectations and needs. It promotes the implementation of better brand value, eventually increasing consumer loyalty and trust. Teams may avoid quality problems before they arise and become an issue by applying the standards and procedures specified by a QA program.

 

Based on the size of the company, Quality Assurance (QA) can be broken down into several subtasks. At its heart, the QA process produces a precise quality deliverable. Because software requirements are always evolving and development teams are adding new objectives, the QA team must ensure that the recently introduced objectives do not have a detrimental impact on software quality.

 

How do QA teams judge the quality of software?

 

The quality attributes approach (QAA) and the defect management approach (DMA) are two major approaches used in quality assurance.

 According to the QA standards, a defect is any aspect of software that does not meet the client's criteria. Sometimes developers do not completely comprehend such a need, resulting in design flaws. Poor data management, faulty programming, and incorrect functional logic are all potential drivers of errors.

 

The defect management approach is useful for monitoring faults and establishing categories to describe them according to their magnitude. Control charts can be created by QA specialists to assess the development team's capabilities.

 

On the other side, the quality attributes approach focuses on fulfilling the following six quality attributes:

 

Functionality: Have all the software's functionalities been developed appropriately? Checking  the software's interface with the rest of the system.  Is it capable of handling data with safety? Is it in accordance with all applicable rules and regulations?

 

Reliability: Is software reliable under particular situations (for example, when a component fails)? How frequently do things go south? And how quickly can the system be restored to full functionality following a failure?

 

Usability: Is it easy for users to comprehend how the programme works? How much time and effort does it take to learn how software works?

 

Efficiency: When building software, did the development team use appropriate coding practises? Is the structure built to be as efficient as possible?

 

Maintainability: How easy is it to find and fix a software bug? Is it viable to pinpoint the root of a failure? In the event of a failure, how much effort will it take to fix the code? How reliable is the system's functionality when modifications are made?

 

Adaptability – Can the system adjust to the changes that are made in its surroundings? How simple is it to set up? In a given context, how easy is it to replace a system component?

 

Wrapping Up

 

Quality control is an important part of the software development process. In software development, the fundamental aim of QA is to provide a product that meets all of the client's expectations, whether they are functional or linked to the user interface. If you don't have an experienced QA team in place, shipping a perfect digital product is difficult.
