Which module is responsible for producing and sharing features with other modules?

The producer module is essential in the context of OutSystems because it allows developers to create and expose reusable features that can be shared across different applications or modules. This modular architecture encourages code reuse and helps maintain consistency across various parts of an application ecosystem.

When a feature is encapsulated within a producer module, it can include various elements such as actions, entities, and user interfaces, which other modules can then consume. This promotes a clean separation of concerns, enabling different functionalities to evolve independently, while still allowing them to interact.

In contrast, consumer modules utilize the features defined in producer modules but do not provide the shared features themselves. Therefore, it's necessary for a developer to understand the role of producer modules in developing scalable applications within the OutSystems platform. The other options, like developer and reference modules, do not accurately capture the explicit role of sharing and producing functionalities.
