What is Quality Assurance? Definition from WhatIs com

QA professionals can identify commonly used functionalities and develop them as shared components. Of course, individual teams can select design patterns that are appropriate to them. Some industries, such as pharmaceuticals and food, have to prioritize safety above all.

what is quality assurance

It offers a systematic and straightforward approach for businesses to demonstrate their capacity to consistently provide deliverables that meet customer needs and regulatory requirements. ISO 9001 has become an umbrella term for encompassing various aspects of quality management, such as customer focus, process approach, leadership, evidence-based decision-making, and continual improvement. Unlike quality control, quality assurance does this indirectly and doesn’t focus on the outcomes of individual products. Software quality assurance (or SQA for short) is the ongoing process that ensures the software product meets and complies with the organization’s established and standardized quality specifications. SQA is a set of activities that verifies that everyone involved with the project has correctly implemented all procedures and processes. By analyzing and ensuring that the software products are of the highest quality standards, QA ensures that they meet customer expectations and needs.

Quality Manager

Everyone from the CEO to the intern is responsible for the quality of what they do. Failures resulting from poor governance, ineffective assurance and resistance to change can, and do, have dire consequences for businesses, individuals and society as a whole. Managing quality effectively can enhance your organisation’s brand and reputation, protect it against risks, increase its efficiency, boost its profits and position it to keep on growing. There’s a lot more to managing quality than just manufacturing widgets without any defects or getting trains to run on time – although those things are certainly part of the picture. High-quality documentation also includes testing using media files such as audio, videos, screengrabs, screenshots, or whatever offers the best illustration for a bug. When has it hurt for a second pair of eyes willing to offer an external review?

AI does not just casually learn how to perform its various functions—it requires a vast amount of carefully selected data to be fed to it. They must ensure that the data being fed to the system is accurate, otherwise the AI model will be trained incorrectly. Quality Quality assurance vs. Quality control assurance can lead to cost reductions stemming from the prevention of product defects. If a product is shipped to customers and a defect is discovered, an organization incurs cost in customer support, such as receiving the defect report and troubleshooting.

QC takes place after development, while QA is ongoing.

This particular attribute can get a little tricky since it’s unpredictable to foresee what kind of action the user might take. Here, using multiple usage patterns and combinations while testing helps to determine whether the existing functionality is adaptable. Every single attribute contributes to the measurement of the performance of a product or service to some degree. You can also further use them for both Quality Control and Quality Assurance. Quality attributes are various characteristics of software that determine software quality in systems. They are crucial as they play a massive role in enhancing user satisfaction and requirements, increasing the clarity in software design and offers, or adding more precise definitions to software quality.

After developing a robust QA plan, it’s time to identify key functionalities of the software and design test cases to verify whether those functionalities are working as per designated expectations. Usability is how the user experiences when they use a service or application or interact with one or more of its components. It determines the efficiency, user satisfaction, and overall effectiveness of the product. For example, users shouldn’t encounter any glitches while signing up or logging in.

How Quality Assurance Works

It’s vital to check this attribute because every software-driven system needs to communicate and work in tandem with other systems to perform a wide variety of tasks efficiently. Testers check how the system responds to ambiguous conditions and see whether the software can maintain what it’s worth. However, flexibility gets invalidated by an indecisive flow of functionalities leading to performance, security, and usability risks. UI consistency, easy signup process, clear navigation, and user-friendly error messages contribute to the high usability of an application. All in all, users should never deal with a tough time trying to grasp how to use basic features.

During testing, the QA team puts the features through the wringer, shaking out the bugs and figuring out what isn’t working yet. They take their findings to the people who can make the necessary adjustments (like the coders), then send the improved version back to the QA team for more testing. The QA team meets with stakeholders (product managers, project managers, etc.) to collaborate and understand exactly what the end goal is. By now, you’re probably coming around to the idea that software quality assurance is essential.

What is quality?

Concepts of quality control can be traced back to at least the Middle Ages and the rise of guilds. A craftsman could access a network of connections with other craftsmen and suppliers by joining a guild organization. He could then benefit from the reputation of the guild based on standards of quality in the products produced by its members.

The process also identifies and addresses any problems early on in the testing process, automatically delivering a better customer experience. This quality assurance approach focuses on setting quality standards and procedures at an organizational level to measure, evaluate and solve quality management issues. This method relies on a thorough gap analysis of the different business processes related to quality assurance. Quality assurance helps ensure that organizations create and ship products that are clear of defects and meet the needs and expectations of customers.

You can use an automated tool to customize the process to suit the specific requirements of the product or service under test. Statistical Process Control uses statistical techniques to monitor and control various production processes. The use of control charts is common for tracking processes and performance, identifying variations, and taking the necessary corrective actions over time. Training and education functions offer knowledge-providing and skill-enhancing employee programs to deepen their grasp of quality processes, principles, and standards. This way, organizations can ensure that their workers have the knowledge and skills to contribute fairly to quality maintenance and improvement efforts. QA functions for standardization and documentation mark a clear focus on the creation and maintenance of documents related to the quality of a service or product.

  • QA standards have changed and been updated over time, and ISO standards need to change in order to stay relevant to today’s businesses.
  • AI is now able to handle this task and, in doing so, is able to find new bugs and issues with code that previously would not have been found without spending countless hours of manual testing.
  • ProjectManager gives you quality assurance from the start to the finish of your project.
  • After executing the quality audit and analysis, the next step would be to introduce the recommended changes in project processes through a project review process.
  • This provides a systematic measurement and comparison with a standard, along with a monitory of processes and a feedback loop to make sure no errors pass through production.
  • Sure, it involved the use of sophisticated tools, but the programmer was still running numerous tests, searching through lines upon lines of code and applying fixes one by one.
  • QA ensures effective and consistent testing practices by setting up set procedures and standards for testing.

If the organization addresses any problem areas within a given time frame, then it receives certification. Learn about the history of quality assurance, why it’s important, and how the International Organization for Standardization attempts to apply quality assurance standards globally. This testing process is the last phase of functional testing and ensures the project or product necessities satisfied. We also own the International Register of Certificated Auditors (IRCA), which includes 10,000 management system auditors in over 150 countries. Quality Assurance is more of a proactive process, unlike Quality Control, that’s reactive.
