capturing all of the specifics she needs.

Interview 5Interview 5

Chapter 4: E-2Discussion ways that Anna might improve her questions for next time.

The interview with Dot contained a lot of information. This is mostly because of Dot's position in the company. However, it seems as though (for a time) anna lost control of the interview. The prime example of this is when she asks Dot about the specific weaknesses of the system and dot basically dumps a lot of hardware issues on her. Many of these issues could have been delt with a little more if she just asked some more probing questions. Also, it seems as though Anna (the interviewer) is trying to find out specifics of the old system but she never gets too much info. She wants to know what some of the good parts are but never gets that information other then "Easy to use".. great.. but how was it easy to use.

Interview 1Interview 1

The interview with Mike is really short which is the fundamental problem for this interview. In order for Anna to get a more focused Mike (who is taking phone calls during the interview time) perhaps she should have scheduled it for a different office instead of when he was on the job. At the very least, Mike would have more time to focus. Since he mentions the warranty several times (because it is very important to him) she could have asked a few more probing questions on that topic.

Interview 2Interview 2

The interview with Cher just seems to go downhill right away. To start off with the first question that she is asked she never really answers. and the follow-up is either never really answered either or is not answered correctly. Anna is trying to find out a rough number of software packages that they use but does not seem to get that information. Barely even a rough estimate. but she never asks specifically. She rarely asks any probing questions either instead seeming to gravitate towards more of the open ended style of questions.

Interview 3Interview 3

The interview with Paige is closed question paradise. Anna goes and starts asking some good closed ended questions but never asks anything really probing. For example, she asks about site licenses but never follows up with anything like "who are they from" how many of these do you have? It just seems like the whole interview is rushed and that there is no depth to the conversation.

Interview 4Interview 4

In the Information Center interview, it looks like she is not asking to many probing questions. Mr. Perteks says "We do a lot of training" never the interviewer follows it up with a "What kind of training" Classroom or Remote?" They discuss that they do some small consulting themselves. But the interviewer never asks if there needed to be any tracking for those questions perhaps a knowledge base of some sort.
