Chat with AIExam 12: Systems Analysis and Design
How does a systems analyst gather the required data when he/she is defining a problem during the preliminary investigation phase?
(38) 
VerifiedDetermining what information is needed, by whom, when, and why is accomplished by interviewing and making observations. If the information system is large, this survey is done by a systems analyst. If the system is small, the survey can be done by the end user.
Discuss the systems audit and periodic evaluation activities.
(37) VerifiedThe systems maintenance phase is an ongoing activity with two parts: a systems audit and a periodic evaluation. In the systems audit, the system's performance is compared to the original design specifications. This is to determine whether the new procedures are actually furthering productivity. If they are not, some redesign may be necessary. After the systems audit, the new information system is further modified, if necessary. All systems should be evaluated from time to time to determine whether they are meeting the goals and providing the service they are supposed to.
These tools, also called computer-aided software engineering (CASE) tools, are used in system analysis to evaluate alternative hardware and software solutions.
