📙 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.
