Which principle emphasizes keeping related code together in Sitecore development?

The principle that emphasizes keeping related code together in Sitecore development is the Common Closure Principle. This principle states that classes that change for the same reason should be packed together. In practice, this means that if a certain piece of functionality within your application requires modifications, the related classes should be implemented within the same module or component. This approach not only reduces the chances of breaking changes during updates but also improves code maintainability and readability.

By adhering to the Common Closure Principle, Sitecore developers can ensure that their codebase is structured in a way that is coherent and logically organized. This becomes particularly important in a complex environment like Sitecore, where interdependencies between items, templates, and code can quickly become intricate. As a result, managing such dependencies aligns closely with the core intent of the principle, fostering a more sustainable approach to development and ensuring that related components are considered together during changes.

Other principles mentioned, like the Common Reuse Principle, focus on different aspects of code organization and reusability, but they do not specifically address the grouping of code that changes together in terms of delivery and maintenance. Similarly, the Reuse-Release Equivalence Principle speaks to the relationship between the release and reuse of code components, while the term Common Collective Principle
