Agarwal and Tanniru conducted a field experiment to evaluate the effectiveness and efficiency of structured versus unstructured interviews, using both novice and experienced interviewers. The experiment was conducted to compare the efficiency and effectiveness of the cognitive interview with the standard information requirements interview. However, the experimental results did not indicate that structured interviews enhanced recall. This triggered the experiment using the Cognitive Interview.
This experiment is to test the effects that the Cognitive Interview has on memory and recall. Two hypotheses are tested in this experiment. The use of a theoretically grounded interview technique will provide a more efficient collection of

By random, a reference librarian was interviewed using either technique by an interviewer trained in both.
The dependent variables: (1) the number of events elicited per each interview (efficiency), and (2) the degree of completeness of details recalled per event (effectiveness) were examined.
Cognitive interview was found to be both more effective and more efficient than standard interviewing techniques in eliciting episodic knowledge from reference librarians. In order for the cognitive interview to be considered an effective interviewing technique, more than one rater must determine that the degree of completeness of details of the events collected under the CI are higher than those collected under the SI.
All interviews were conducted in private rooms individually. The interviews were conducted at the institute of each patron. Ten students enrolled in a senior-level expert system class who received training on the SI and the CI during regularly scheduled class time. No one involved knew of the details of the experiment or the types of techniques being tested. Interviewers received course credit and monetary compensation for their participation.
The interview has long been part of the systems professional’s repertoire of elicitation tools, used extensively in both requirements analysis and knowledge acquisition. It is said that there are some drawbacks associated with the use of interviews. Open interviews are seen as
The interviews will be recorded and notes will be taken so the interviewer and build a plan and determine the system requirements of the new human resource system. It is crucial that the interviews and interview questions be well structured to gain the highest quality of information gathered during the interviews. The quality of information gathered is just as important as the quantity as described by Havelka and Sooun (2002): “Interaction between users and IS personnel was described as the quantity and quality of communication and the amount of group activities performed, including feedback from and to one another during the process”. Proper communication and collaboration is critical in the beginning phases for collecting and large quantity of good quality information.
Research on interviews has generally shown that standardized procedures are higher in their reliability and validity than unstructured interviews. Learning how structured
The same interviewer conducted all the interviews and he adopted a consistent approach in attitude and to questions. The guide served as the researcher's checklist, meaning that he looked through it when interviewing to make sure the topics in the guide was covered in the interview. The participants did not receive the exact same questions but all were asked about the same topics, e.g., if the participant was freely talking, only a few questions within the topics were necessary, while more questions were asked if the interviewee needed more guidance on a given subject. Questions were always asked openly, and adjusted to the specific interview.

According to the lecture on Scenario Development, what are the two basic methods of obtaining an informational interview?
(iii) Interviews can be more personal way to getting more out of the respondent and get the true story behind someone’s experience. This method could be used in the workplace to measure productivity.
Unstructured interviews are not made up of prepared questions. The interviewer will ask more open questions about board topics and then use follow-up questions to gain more answers in further detail. This method of interview is time-consuming however it enables the interviewee to answer questions in more detail and depth. It is possible that audio-recordings can be

Whereas a structured interview follows a standardised format, in an unstructured interview the interviewer has complete freedom to vary the interview. Supporters argue that this brings a number of important advantages. Such as, rapport and sensitivity, the interviewee's views are clearer, the ability to check understanding, flexibility and the ability for the interviewer to explore unfamiliar topics. However, there are multiple disadvantages to using unstructured interviews in sociological research. Such as, practical problems, which include, time and sample size, training, and interpersonal skills, there are also issues with representativeness, reliability, quantification and validity.
For the second part of my assignment, I was asked to do a reference interview. This for me was the most exciting part of the assignment, since I haven’t asked a library professional for help since I was in elementary school. I was anxious to see how the librarian responded to me and was interested in the quality of the resources we might find. Again, like the first part of the assignment, I wanted to pay close attention and look at my interview experience with fresh eyes. I wanted a different environment than what I experienced at the music library, so I chose a different library.
The handwritten notes led to losing some data regardless of the speed in writing the responses. Also, it was more difficult to make observational notes while taking notes. Nevertheless, to avoid missing data as much as possible, processing the data took place straight away after each interview while the received information was still fresh. Also, it was considered that it is time-consuming to transcribe all the tape-recorded interviews which were held for an average 40 minutes. A 40-minute interview took, on average four hours to transcribe. Furthermore, the interviews could have been weaker if they have been recorded because of the interviewee’s discretion and
Interviewing is a procedure which recounts to a controlled situation in which one person asks a chain of questions to another person, relating to a
