these technical resources are sufficient for the proposed system or not
Economic Feasibility: Economic feasibility is the most important study that determines the
cost and benefits of the proposed system and compares with the budget
Operational Feasibility: determine whether it is operationally feasible or not, (whether the
system will operate in the way that user wants.)

competitive necessity, more timely information, improved organizational planning, and increased
organizational flexibility.
5.Discuss why some systems developers believe that a data model is one of the most
important parts of the statement of information system requirements
Ans

the characteristics of data captured during data modeling are crucial in the design of
databases, programs, computer screens, and printed reports.

data rather than processes are the most complex aspects of many modern
information systems and thus require a central role in structuring system
requirements.

the characteristics about data are reasonably permanen
8. List and briefly describe the five activities of systems analysis.
Ans
-Gather detailed information
- Define requirements
- Prioritize requirements
- Develop user interface dialogs
- Evaluate requirements
9. What is the difference between functional requirements and non-functional
requirements?
Ans
- Functional requirements are things the system does.
- Non-functional requirements are quality attributes or aspects of how the system is designed,
built or implemented.
