What does the Feature layer primarily focus on in Sitecore Helix?

The Feature layer in Sitecore Helix is centered around business requirements, making it fundamental to the overall architecture of a Sitecore solution. This layer is where the specific features that address the business needs are defined and developed. It encapsulates the functionality that a particular aspect of the application requires, allowing for a clear alignment between technical development and business goals.

By focusing on business requirements, the Feature layer ensures that the development of the Sitecore solution is directly tied to the strategic objectives of the organization. This alignment not only helps in achieving the desired outcomes but also aids in prioritizing features based on business value.

While other layers such as the Technical architecture, Sitecore items organization, and Data access layer contribute to a robust Sitecore application, they do not specifically drive the functionality from a business perspective like the Feature layer does. Thus, emphasizing business requirements reflects the unique role this layer plays in the Helix architecture.
