What feature of OutSystems allows rapid application development?

The feature of OutSystems that facilitates rapid application development is the use of visual development tools and reusable components. This approach allows developers to design applications through graphical user interfaces, which significantly speeds up the development process compared to traditional coding methods.

Visual development tools enable users to drag and drop elements onto a canvas, making it easier to construct user interfaces and workflows without extensive manual coding. This not only reduces development time but also lowers the learning curve, allowing even those with limited programming experience to contribute to application development.

Additionally, the availability of reusable components fosters greater efficiency. Developers can leverage pre-built modules, templates, and services, which can be customized to meet specific needs without having to build everything from scratch. This promotes consistency across applications and enhances collaboration among team members, as they can share and utilize existing work effectively.

In contrast, options that suggest extensive manual coding requirements or writing all code from scratch would hinder the rapid application development that OutSystems aims to provide. Similarly, limited template options would restrict developers' abilities to build upon existing structures, further impeding progress.
