Unlocking Success: 7 Key Practices for Software Quality Assurance
When it comes to software development, ensuring the quality of your product is crucial. Truth be told, many startups fail because they don’t pay enough attention to quality assurance (QA). QA is actually a helpful asset in this field, preventing the release of buggy and unreliable software that could lead to serious financial losses.
Take the example of Flud, a social news reader app. It was considered innovative but flopped due to poor QA. The development team was so focused on creating code that they overlooked testing thoroughly. When Flud was launched, it was riddled with bugs and glitches. Even though they tried to fix everything later, the damage was done, and Flud had to shut down.
To avoid such disasters, we need effective QA management. This involves using tools and methods to build software that’s free of bugs. So, today, we will look into seven key practices that can make or break your software’s quality.
What Are the Quality Assurance Practices?
Quality Assurance (QA) is a process in software development aimed at ensuring consistent product quality that aligns with user expectations. This approach involves several key practices:
Key Practices: No matter what the product is about, these are some of the most important practices of this approach.
