Text b: System Analysis

System analysis involves a detailed study of the current system, leading to specifications of a new system. Analysis is a detailed study of various operations performed by a system and their relationships within and outside the system. During analysis, data are collected on the available files, decision points and transactions handled by the present system. Interviews, on-site observation and questionnaire are the tools used for system analysis. Using the following steps it becomes easy to draw the exact boundary of the new system under consideration: a) keeping in view the problems and new requirements, b) workout the pros and cons including new areas of the system.

All procedures, requirements must be analysed and documented in the form of detailed data diagrams (DFDs), data dictionary, logical data structures and miniature specifications. System Analysis also includes sub-dividing of complex processes involving the entire system, identification of data store and manual processes.

The main points to be discussed in system analysis are:

• Specification of what the new system is to accomplish based on the user requirements.

• Functional hierarchy showing the functions to be performed by the new system and their relationships with each other.

• Function networks which are similar to function hierarchy but they highlight those functions which are common to more than one procedure.

• List of attributes of the entries — these are the data items which need to be held about each entry (record).
