What should be included in the Solution Design document following a feature change?

The Solution Design document is essential for capturing the details surrounding any feature change in a project. Including documentation of the feature change serves multiple purposes. It provides a clear understanding of what the change is, why it was implemented, and how it impacts the overall system or application. This documentation should outline the objectives of the change, the expected outcomes, any modifications to existing functionalities, and any new functionalities that may be included.

By documenting these details, it facilitates communication among team members, stakeholders, and any future developers who may work on the project. It allows for alignment on goals and expectations and serves as a reference point for testing and validation phases. The inclusion of this information helps ensure that the implementers are following a well-defined process and promotes consistency throughout the project lifecycle.

While the other options—marketing strategy details, technical specifications only, and training materials for users—are important in their respective contexts, they do not encompass the core aspects necessary for understanding and implementing a feature change as comprehensively as documentation of the feature change does.
