Which of the following is a key benefit of using OutSystems for mobile app development?

The key benefit of using OutSystems for mobile app development lies in its ability to facilitate fast development and integrated testing. OutSystems is designed with a focus on low-code development, which significantly accelerates the process of app creation compared to traditional coding methods. This allows developers to rapidly prototype and iterate, reducing time-to-market and allowing for quicker responses to changing business needs.

Furthermore, OutSystems provides tools that integrate testing seamlessly into the development pipeline. This often includes automated testing capabilities that ensure the app works properly on various devices without the need for extensive manual testing. This integration helps in identifying and addressing issues early in the development cycle, enhancing overall efficiency and quality.

In contrast, the other options highlight negative aspects that are not characteristic of OutSystems. For example, high maintenance costs, long development cycles, and limited platform compatibility are not features associated with OutSystems, as the platform specifically aims to lower maintenance overhead, streamline development time, and support a wide range of devices and operating systems.
