In this the willingness and ability of management, employees, customer suppliers and others to
operate, use and support a proposed system is studied.

Task Make distinction between organizational feasibility and economic feasibility.

1.1.3 Analysis

This is the next stage of development process of Information System. It is applicable to both, i.e.,
for making an entirely new system or improving or replacing the existing one. Some activities
of this stage are the next step of feasibility study but it is not a preliminary study like feasibility
study. It is an in-depth study and results in the functional requirement hat provide the basis for
system design. System analysis involves knowing the information needs of the end user and the
organization employees, what are the resources activities and products presently available and
the information system capability to meet these information needs.
The process of system analysis starts with analyzing the organization’s present system if any,
and functional requirement analysis.
To achieve effectiveness in Information System one must know something about the organization
like, about its culture, management their experience, qualification, attitude towards computerized
Information System, organizational values & norms/organizational working, etc. in detail, in
general and specific to each organizational unit so that a balanced Information System comes
into existence.
If the company has some information system in existence then it is very important to analyze that
system. In this, one must analyze each component of system like hardware, software, people
resource, networking and data resources. Whether the existing system serves the purpose of
management or it is lacking at some end to serve the solution of information need, so that proper
action should be taken at the time of designing the system so that these loop holes can be removed.
Functional requirements are end user information requirements that comprise of:
1. User interface requirements: In which one determines what type of input and output
requirements of the user are there. It also includes source, formats, contents, etc., of each
input & output media.
