Answers

31.	Answer :   (e) Reason:    TPS capture and record information about the transactions that affect the organization like the sale of an item, a withdrawal from ATM etc.
32.	Answer :   (b) Reason:    Can’t easily go back to previous phases as each phase would get “signed off”.
33.	Answer :   (e) Reason:    Resource feasibility determines availability of team, computer resources, and support staff.
34.	Answer :   (c) Reason:    Maintaining Constant staff, decreasing operating expenses, reducing error rates and ensuring quicker processing and turnabout fall into the category of tangible costs which can be measured in terms of money whereas survival cant me measured.
35.	Answer :   (c) Reason:    PERT/CPM is represented by rectangles whereas ROI and NPV are Return on investment and net present value.
36.	Answer :   (e) Reason:    Models to manage the development process are: ·         PERT / CPM chart ·         Gantt chart ·         Organizational hierarchy chart Whereas DFD model is used for system components.
37.	Answer :   (d) Reason:    In context level diagram data store is not used.
38.	Answer :   (e) Reason:    Program modules should be loosly coupled and highly cohesive.
39.	Answer :   (e) Reason:    Usually JAD sessions are conducted in special rooms, Off-site location may be good, but need access (phone etc.) to executives and technical staff not present. Resources required are Overhead projector, Black or white board, Flip chart, adequate work space.
40.	Answer :   (a) Reason:    System analyst uses use case to work with users to determine system usage.
