When organizing modules in your Sitecore solution, what should they be based on?

Organizing modules based on functionality is a best practice in Sitecore development. This approach allows developers to create reusable components that serve specific purposes or capabilities within the solution. When modules are categorized by functionality, it fosters clarity and improves maintainability, making it easier for developers to locate, update, and manage different aspects of the application.

For instance, if a module is designated for content management, it can encapsulate all related components like templates, rendering, and workflows, which streamlines collaboration among teams and supports modular development. By focusing on functionality, developers can ensure that various parts of their Sitecore solution are logically aligned, enhancing the overall architecture of the project.

Other approaches such as organizing by type of layer, module size, or code language might not provide the same level of cohesion and clarity as functionality-based organization. While these factors are important considerations during development, they do not offer the same strategic alignment that functionality does in terms of modular design.
