While most research in requirements traceability focuses on tracing requirements to other artifacts, this paper studies a method of tracing requirements to humans: who was involved in the creation of the requirement, who is responsible for the requirement, who needs to be informed of changes to the requirement, what is the loss of knowledge if a person decides to leave. The authors closely followed the initial discussions through the sixth iteration of the requirements and design specifications. They observed all meetings, took notes and audio recordings, and photocopied all tangible artifacts produced. The authors maintained a record of 166 main artifacts that were produced and the people involved in their production.

Using this approach, the authors were able to answer the questions listed above about the case that they studied. Members of the company involved agreed that the conclusions regarding contributions to requirements were correct. The authors' model was able to identify the right people to correct misunderstandings about requirements, the people involved in a requirements change, and how to handle staff turn-over. The authors conclude that their approach is a practical and feasible way to answer questions about the human contributions to requirements.
