A crucial phase of the software development lifecycle (SDLC), user acceptance testing (UAT) is frequently disregarded or given less importance. However, there are a number of reasons why UAT is crucial and needs to be included in the SDLC, as mentioned below.

Checks that the program complies with user needs: UAT makes sure that the program satisfies user needs. It highlights bugs and flaws that might not have been found during the development and testing phases. This helps the development team in resolving these problems prior to the software’s deployment, ensuring that it satisfies the needs and expectations of the users.

Verifies the performance, usability, and usefulness: UAT verifies the software’s performance, usability, and usefulness. Users are given test scenarios and test cases to conduct as part of UAT, which tests the software in a real-world setting. Before the program is published, any problems are found and fixed using input and findings. This ensures the program operates as expected, is user-friendly, and acts as planned.

Early difficulties in the development cycle are identified: Early in the development cycle, UAT aids in problem identification. It can find bugs that perhaps weren’t found throughout the development and testing phases by testing the program from the end-user perspective.

Decreases the price of post-release repairs: UAT can assist in lowering the price of post-release fixes. The development team may save money by finding and fixing problems during the UAT phase rather than waiting until after the product has been released. Eliminating the need for intensive testing and maintenance once the program is published can save time and money.

More satisfied customers: UAT contributes to higher user satisfaction. Users may provide insightful comments on the usability, functionality, and performance of the product by participating in the testing process. This may contribute to enhancing user happiness and the software’s overall usability.

Increases the quality of software: UAT aids in raising the caliber of software. It can find bugs that perhaps weren’t found throughout the development and testing phases by testing the program from the end-user perspective. This can assist the development team in resolving these problems prior to the software’s deployment, ensuring that it satisfies the needs and expectations of the users.

Promotes security: UAT contributes to improving software security. It may find security flaws, including malware attacks, unauthorized access, and data breaches, by testing the program in various circumstances. This can assist the development team in fixing these flaws and making sure the product is secure before it is made available.

Conclusion

UAT puts actual users through the software testing process and does it in a real-world setting. This might lessen the likelihood of post-release patches and upgrades by identifying problems and flaws that might not have been found during the development and testing phases.
