Solutions

Expert Solution

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.
