Systems Development Life Cycle is composed of five phases. If you have been hired to develop an information system for your university. Indicate for each case in which phase you are when handling each of the following reports with justifications.
1. You obtained report showing whether the information system is feasible or not
[ Select one]
a. Maintenance
b. Implementation
c. Design
d. Investigation
e. Analysis
2. You want to correct error that when the system is running
[ Select one]
a. Maintenance
b. Implementation
c. Design
d. Investigation
e. Analysis
.
3. You obtained the system requirements in the form of logical model
[ Select one]
a. Maintenance
b. Implementation
c. Design
d. Investigation
e. Analysis
4. You obtained system specification from a logical model
[ Select one]
a. Maintenance
b. Implementation
c. Design
d. Investigation
e. Analysis
Question 1: You obtained report showing whether the information system is feasible or not
Answer : d. Analysis.
Explanation: Feasibility study is done in the analysis phase of system development life cycle. Post gathering all the requirements of the software to be developed, we analyse if it is economocially and technically feasible or not.
Question 2: You want to correct error that when the system is running
Answer: a. Maintenance.
Explanation: Corrective maintenance of a software to fix bugs or errors. Or to provide security patches to loopholes.
Question 3: You obtained the system requirements in the form of logical model
Answer: Analysis
Explanation: Requirements are elicited in the requirement analysis phase and documented into a legal document called SRS.
Question 4: You obtained system specification from a logical model
Answer: Design
Explanation: Design phase chooses the best architecture of all the proposed solutions so that efficiency of the SDLC is increased.
