Final answer:
The traditional means of requirements elicitation is Interviews where stakeholders are directly questioned to gather vital information. Participant observation is likely the method a symbolic interactionist would use, and using existing records for research is known as naturalistic observation.
Step-by-step explanation:
The traditional means of requirements elicitation includes several methods such as interviews, observations, and the use of scenarios. Interviews are a fundamental technique where stakeholders are directly questioned to extract information. Observations involve watching end-users or systems in action to understand the requirements. Scenarios, on the other hand, involve creating specific narratives or use-cases to explore system requirements. However, among the options provided, B. Interviews are considered the traditional means.
When considering which research technique would most likely be used by a symbolic interactionist, b. Participant observation is a strong candidate because it allows the researcher to deeply understand the behavior and social interactions within their natural context.
If researchers are using existing records to try to answer a research question, this is known as a. naturalistic observation. This form of research does not involve manipulating variables but instead studying phenomena as they naturally occur.
