13.6 Summary

 Two principal methodologies for establishing the essential information requirements of
the organization as whole are enterprise analysis and success factors.
 Enterprise analysis argues that the firm’s information requirements can only be understood
by looking at the entire organization units, functions, processes, and data elements.
 The strategic analysis, or critical factors, approach argues that an organization’s information
requirements are determined by small number of critical success factors (CSFs) of
managers.
 Business Process Reengineering (BPR) is known by many names, such as ‘core process
redesign’, ‘new industrial engineering’ or ‘working smarter’.
 With the development of information technology, system analysis too, develops more
and more vigorously and has a significant role in a life cycle of an IT application and of IT
projects in general.
 Analysis focus on systems’ requirements specification and clarification and is the stage,
when system designers have to work at two levels of definition regarding the study of
situational issues and possible solutions in terms of “what to do” and “how to do”.
 The system analyst is a key member of any systems development project.

 The system designer details the system specifications that will deliver the functions
identified during systems analysis.
