PROJECT REPORT Callipers – The Training Manager
System Analysis is the first step in developing and
managing systems. The first step in the system development life cycle is the
identification of a need. This is a user‘s request to change, improve or enhance an
existing system. The preliminary investigation is one way of handling this. The
objective is to determine whether the request is valid and feasible before a
recommendation is reached to do nothing, improve or modify the existing system
or build a new one. Once the request is approved, a project proposal will be
prepared.
It‘s a detailed of various operations performed by a system
and their relationship within and outside of the system. The main aspect of
analysis is defining the boundaries of the system and its interaction with other
systems. Data are collected from files available, transaction handled by the present
system and so on. The various tools used are dataflow-diagrams, interviews, and
questionnaires etc. Training, experience and common sense are required for
information collection. At the end of this phase, a firm understanding of what is to
be done is obtained.
2.1 Feasibility Study
Feasibility represents the overall logic to construct software depending
upon the knowledge implied by the requirement analysis. The idea here is to
whether it is really possible to achieve the stated objectives or objectives that are
quiet vague in terms of their practicability. In other words it is to be determined if
the stated goals are too ambiguous or actually are less ambiguous, whether they
are clear or provide confused pictures in real terms.
