2；Prospective traceability allows for links to be captured in an online fashion, incrementally improving the system’s traceability and allowing developers to
immediately benefit from the trace links created.
3. Another benefit of prospective traceability is the presence of addition captured information, such as the temporal sequence of user actions in the design environment, which can be used to automatically generate trace links to heterogeneous artifacts.
