Interviewing can be an effective method for determining system requirements for a new system if the interviews are conducted well. One important aspect of a good interview is the type, context, and quality of the interview questions. There are two primary types/approaches to the questions, each with their specific purpose. Match the following statements with its question type. These questions have no pre-specified answers. For these questions, a range of specific answers are provided to choose from. These questions allow you to probe for more in depth answers. These questions are limited in the depth of information received but can be useful in providing insight without significant time commitment.
