What is Software Quality?
We can calculate the Software quality is based on the number of variables. Those variables can be divided into external & internal quality criteria. The external quality represents the user experiences during the running the software application, whereas internal quality refers to code-dependent, and that are not visible to the end-user.
Software Quality is the confirmation that the software is meeting its requirements. And we can check whether the software is meeting the quality or not by using two factors like Validation and Verification.
As per the ISO standard, the Software Quality means “the totality of features and characteristics of a product or service that bears its ability to satisfy stated or implied needs.”
Attributes of Software Quality
From the customer aspect, the quality of the product includes the below things:
- Good design
- Good functionality
- Good after-sales service
- Value for money
Good Design: As we know that the good looks & style of the application can attract the customers. So its very much important that the application should have a good design, user-friendly, and meet all the requirements of the customer. So there are few everyday things into consideration that the right colour for the application, font size, and styling of the web elements.
Good functionality: With Good looks of the application, the functionality of the application should work as expected. There should not be any deviation between the actual result and the expected result.
Reliable: acceptable level of breakdowns or failure: After complete the Good looks and Good functionality, we have to test the application reliable. For example, – Lets there is a system that can store employee details, and it should not fail after the certain number of entry of the employees. This is called reliability.
Consistency: As we know that an application can run on multiple platforms, so its more important that your application behaves the same in all platforms. And that is called Consistency.
Durable: lasts as long as it should: The Developer application should be run for a long time without failing that called durable. For example- by using a web application, you can insert 100 employees’ details. Still, after 100 employees, if you have entered more employee details, then it should continue without any functional breaks of the application.
Good Service: The very first thing that comes to the picture is Service after release or ship the product to the product owner. So its very important to provide the best service to make the customer happy and satisfied.
Scalability: How easy is it to extend a feature? Or to add a new one? Or to add extra cores, or increase the size of the cluster the application runs on? Again, this is all about software architecture and anticipating future needs.
Software quality is the result of the user experience. But software quality should not and cannot be a reactive action to external defects. Software quality is built from the ground up, with design and development methodologies, and with a special focus on testability, coverage, and flexibility.
In this article, we have discussed several aspects of Software Quality like reliability, testability, the maintainability of code, and the rate of delivery. Testing is the basic way to measure all aspects of software quality, regardless of how quickly software must be released. The pressure to release software on time calls for the adoption of more software test automation, especially for GUI testing, which can be arduous.
Testing on its own is not enough to check and improve on software quality, though. It’s also important to use high-quality test metrics when evaluating the software. Test metrics measure the quality of any software testing effort. Without the right test metrics, errors are more likely to infiltrate production.
High-quality software results from a combination of comprehensively testing the main drivers of software quality and using test metrics to ensure the testing effort is effective.
