What is the key benefit of using OutSystems' visual development approach?

The key benefit of using OutSystems' visual development approach is the increased speed and efficiency in app development. This method allows developers to create applications quickly by utilizing a graphical interface, which streamlines the process of designing, building, and deploying apps. The visual development environment enables rapid prototyping and iteration, allowing teams to respond to changes and feedback more effectively.

Additionally, this approach encourages collaboration among team members, as stakeholders can visually understand the application's structure and functionality, leading to a more cohesive development process. The use of pre-built components and templates also contributes to faster development times, as it reduces the amount of manual coding needed.

The other options do not align with the core advantages provided by the visual development methodology. Greater control over manual coding does not align with the visual development principle, which emphasizes efficiency and reduced coding demands. Enhanced complexity in app architecture contradicts the intention of simplifying the development process. Lastly, while testing is still a crucial aspect of app development, a reduction in testing requirements is not a direct benefit of visual development; in fact, thorough testing is essential to ensure quality, regardless of the development approach used.
