Software quality assurance (SQA) is a process that ensures the software has been built, delivered, and maintained following the requirements of the customer. It also ensures that the software meets all quality standards and complies with regulatory requirements.
This process is vital for businesses, especially startups, as it helps them avoid costly mistakes. It also helps them ensure that their products are on par with similar products from other companies.
It also involves several activities, such as testing, monitoring, and analysis. It also includes measuring the performance and reliability of software products.
When it comes to this process, there are specific markers or quality metrics that you need to keep in mind to ensure that everything is running smoothly. This article will cover the essential metrics you need to know to enhance your software quality assurance process.
Why are software quality metrics important?
You can see the importance of software quality metrics in how you use them to improve the product’s quality and reduce development costs. Software quality metrics also help to identify bugs, defects, and risks early in the development process.
Software quality assurance has three primary purposes:
- Identify problems before they happen: Quality assurance helps identify risks, defects, bugs, or other issues before they cause problems for customers or developers.
- Reduce the cost of development: Quality assurance helps reduce costs by identifying potential issues early in the development process and addressing them quickly.
- Improve customer satisfaction: Quality assurance helps create a better customer experience by ensuring that their needs are met through effective communication with them throughout the development process.
It is a crucial factor in the success of any product or software. With that in mind, let’s cover six essential quality metrics you should look at during the process.
1. Reliability
Software quality assurance is an essential part of the software development process. It helps ensure that the software meets its functional requirements, security, and performance standards.
You can use several metrics to measure software quality. The most common one is the defect density metric. This metric measures the number of defects per 1,000 lines of code written, and it’s a good metric for measuring the reliability of a software product.
You can also include the quality of software support after software failure as a part of this metric since you want to know how efficient you can be once you encounter an unexpected software failure.
2. Functionality
Functionality is a metric that can measure whether or not your software has met its goal. It can also be a way to measure how much time it took for you to build your software in comparison with other teams in your industry.
There are many reasons why you should measure functionality as a metric for your software quality assurance process.
One of the most important reasons is that it helps to identify and prioritize the bugs in your software. It also allows you to improve the quality of your software.
Lastly, it helps ensure that you provide value to your users.
3. Performance
If you test the software in a lab, you try it for the ideal performance. But what about the version of the software in real-world conditions?
One of the most critical aspects of software quality assurance is measuring performance. You can do it using metrics such as response time, customer satisfaction, etc. The metrics facilitate decision-making and explain how well a product performs in different scenarios.
You should measure your SQA process performance because it allows you to make decisions based on data rather than gut feeling or opinion.
4. Security
An important metric in software quality assurance is security. Security includes things like the ability of a system to protect against malicious code, unauthorized access, and data theft.
Security as a metric helps determine whether or not your software will be usable in the future or if it will need any adjustments.
You should measure this metric to identify potential risks and improve the product’s security. It helps identify potential vulnerabilities and bugs before hackers, or malicious entities exploit them.
5. Budget and timelines
Measuring the budget and timeline as a metric for your software quality assurance process is vital. You should measure it because, with time, the scope of work increases, and often multiple stakeholders are involved. This situation makes it harder to track progress, so it is crucial to clearly understand what tasks you need to do and how long they will take.
The following are some other reasons why you should measure your budget and timelines as a metric for your SQA process:
- It provides insight into what you can do with more resources or less time.
- It helps prioritize features, tasks, or bugs according to cost or timeline.
- It keeps everyone accountable for their work related to the project’s goals.
For every project that you undertake, make sure that you keep track of your budget and timelines.
6. Maintainability and code quality
You should measure maintainability and code quality as a metric for your software quality assurance process because it helps you identify bugs and other problems in your code early on. You can also use this metric to measure how well your software is performing based on how long it takes for you to fix an issue.
This metric can also determine how long it will take for you to deliver a particular feature or product.
Conclusion
By measuring these key quality metrics during your software quality assurance process, it will be easier for you to spot flaws and act on them immediately before anything worse occurs. Aside from that, it makes you better prepared to take on future endeavours and can help you create better plans and processes.
