What process ensures that requirements and designs at different levels are aligned?

The alignment of requirements and designs at various levels is achieved through the process of traceability. Traceability is essential in business analysis because it provides a means to maintain the relationships between requirements and their source, as well as between requirements and the corresponding designs, implementation, and testing artifacts. It allows analysts to track these connections throughout the project lifecycle, ensuring that each requirement is addressed in the final solution and that design decisions can be justified by linking them back to the original business needs.

This alignment helps to facilitate change management by allowing stakeholders to see the implications of any changes in requirements on designs and vice versa. In addition, traceability ensures that all parts of the project remain consistent with the project's goals and objectives, providing confidence that the end product will meet the expectations set out during the analysis phase.
