Software Quality Management (SQM) is the process of constant improvement of the product quality, integrated into the development process until the expectations are achieved. Software quality management aims to create a working environment where quality is the responsibility of everyone in the team.
Many teams and people might have to collaborate and work together to fulfill their roles and responsibilities to make this process successful. This will also demand you collaborate closely with your product development team to ensure that you meet your quality goals.
Software Quality Management is important because it helps to identify and correct errors in software, which is essential for the effective implementation of a project. The quality of the software is simply the measurement of how well the product has been able to fulfill your needs.
It is measured by how often errors are found and repaired, how well the software works under different conditions, and how easily software can be maintained.
Software quality is determined by comparing actual results against the expected results. If a project fails to meet its objectives because of poor quality, then the project will be a failure. Software quality can include a large variety of factors such as degree of completeness, efficiency, usability, correctness, and reliability.
The five aspects of software quality:
Software quality can be measured in terms of its ability to perform its required functions and meet its specified requirements. The five aspects of software quality are:
- Performance: Performance refers to how well a system performs its functions or meets user requirements.
- Usability: Usability relates to the ease with which users can use the system and understand it.
- Reliability: Reliability relates to the ability of a system to continue operating without breakdown or failure.
- Maintainability: Maintainability refers to how easy it is to understand and modify code so that changes can be made easily when necessary.
- Interoperability: Interoperability refers to whether a system will work with other systems or programs without difficulty or incompatibility issues.
How to adopt Software Quality Management?
Test at the right time
Effective software quality management means knowing when to test. You must know what would be the right time to test the software products so that you can get maximum outcomes from it. This means you need to have a good understanding of what the user needs and what their expectations are, and then plan your testing accordingly.
You should always try to do things in a way that’s easy for users, as well as for yourself and that makes sense within your organization. If you’re doing an e-commerce site, for example, then testing before launch might be difficult for you because there won’t be enough time or resources to fully test everything before release. But if you have the resources, then there isn’t any excuse enough to not conduct the user tests.
Improve testing organization
This means creating a team that can effectively test the software and deliver results so that they can be analyzed and analyzed again. It also means designing the QA testing process so that it can be automated and using tools such as defect tracking systems to improve communication between testers and developers.
While it’s important to have a good testing organization, it’s also important to have an effective developer organization. If you want your team to produce high-quality software, you need to provide them with the tools they need to do their jobs well.
Innovation leads to improvement
The more innovative you are, the better your software will be. It’s not enough just to have good ideas; you also need to be willing to take risks and try new things so that you can improve your product over time.
Keep reviewing
Keep reviewing your code as you write it. There will be plenty of times when you think you’ve finished the job but then find out something was missed. Or perhaps the code doesn’t do what you thought it would do after all. Having someone else read over your work before committing it is not only good practice; it also helps identify issues early on, saving time later on in the project.

What are Software Quality Management best practices?
1. Separate the security testing and performance testing teams
It is not the responsibility of the security testing team to measure the performance of the software. The reason is that there are many methods to improve performance, but they may lead to security vulnerabilities.
2. Use a bug-tracking tool for quality management in software
A bug-tracking tool is a great way to track software bugs and quality issues. The tool is also useful for keeping track of changes and improvements.
A bug-tracking tool will help you keep track of all your bugs, both known and unknown. It allows you to organize the information into different categories such as severity, priority, and resolution.
In addition, it will help you find out when was the last time someone fixed a particular bug, which helps in determining whether it has been fixed or not. Also, you can use your bug-tracking system as a benchmark for measuring progress on other projects that are similar but have different requirements or complexities.
3. Collaborate closely with your product development team
Collaborating closely with your product development team is essential for a successful SQM. This means that you must be able to communicate effectively with them regularly throughout the project lifecycle. It also means that you need to make sure that they understand what it takes to meet your quality standards and why they must do so.
In addition, you should ensure that they have all the resources they need to do their jobs well, including time, money, and equipment. If necessary, you may have to provide additional funding or buy new equipment or software licenses for them as part of your quality management plan.
4. Try to simulate the end-user environment
You are just developing a product, it will be the end-user who is going to use it. Therefore, you should try to simulate their usage as much as possible while writing and testing your software.
A way of simulating real usage is by using tools like user testing or usability testing. Such tests can offer some real-world feedback that is incredibly helpful to the developers and testers to fix the bugs in the codes before the product is launched in the market.
5. Make use of the two-tier test automation approach
The two-tier test automation approach is one of the most popular and effective ways to develop software quality. The two-tier approach is a combination of manual testing and automated testing, which can be performed in parallel to ensure the whole process is completed within a given timeframe.
6. Run regression tests
The most important software quality management technique is regression testing. Regression testing ensures that software can still be used after changes or new versions have been implemented.
Regression testing is a way to test whether the functionality of a program still works as intended after the software has been modified or upgraded. A user must be able to access the functionality and perform tasks without having their previous experience invalidated by a change in a program.
7. Test Early
One of the most important principles for quality management in software is the ‘Test Early’ principle. It states that you should test your software early in the development process before investing a lot of time and effort into implementing it.
It also helps you to ensure that your product meets your users’ needs as well as your expectations, providing an early indication of whether or not there are any problems with the design or functionality. If you find an issue while testing, you can rectify it before it becomes a major issue and fix it before it causes any problems for users.
Summary
If you want to develop software that end-users love to use then you have no choice but to implement software quality management best practices. It will not only help you deliver a top-notch quality product to the customers but also help you grow your business as well. Because as you know, the more refined the gold is, the more valuable it is.
Similarly, the more quality your product has, the more users can enjoy it. And that raises the chances of them coming back to you for more. But to achieve high quality, you need to come up with a reliable testing strategy. If you think you can’t create one on your own you can always ask the software development and software testing companies to guide you through the process.
