Analysis is a detailed study of the various operations performed by a
system and their relationships within and outside the system. One aspect
of analysis is defining the boundaries of the system and determining
whether or not a candidate should consider other related systems. During
analysis, data is collected from the available files, decision points,
and transactions handled by the present system. Logical system models
and tools are used in analysis. Training, experience, and common sense
are required for collection of the information needed to do the
analysis.
