2.2.2.2.1 Interviewing
Interviewing
is a
fact
finding technique
for collecting
information
in
face-to- face, phone,
e-mail, or instant messaging discussions [16]. Interviewing is the most effective way to
understand business
function and business rules [14].
Advantages of interviewing:
Personal
contact allows
the analyst to be responsive and adapt
to
what
the
user
says. Because of this, interviews produce high-quality
information.
The
analyst
can
probe
in
greater
depth
about
the
person’s
work
than
can
be
achieved with other methods.
If the interviewee has nothing to say, the interview can be terminated.
Disadvantages of interviewing:
Interviews are time-consuming and can be the most costly form of fact gathering.
Interview
results
require
the
analyst
to
work
on
them
after
the
interview:
the
transcription of tape recordings or writing up of notes.
