Analysis Phase

Involves converting the requirements specification into a problem specification.
The analyst uses data modeling, process modeling, or object-oriented modeling techniques, such as
- data flow diagrams
- data dictionary
- UML diagrams
DFDs, data models, data dictionaries, UML diagrams, etc., are used to develop a problem specification and a system proposal.
During this phase, analysts have their last chance to correct errors and omissions easily and cheaply. (As we advance through the stages of the Systems Development Life Cycle, the cost of correcting an error increases.)

Phase Name: Analysis
Major Function:	To determine the system requirements of a proposed new system.
Input:	Requirements specification
Output:	Problem specification System proposal
Principal Tools:	data dictionary data flow diagrams data models system models prototyping system flowcharts
Personnel & Tasks:	Users must continue to be heavily involved. The analyst diagrams the functions of the new system without specifying exactly how those functions are performed. The analyst may prepare a prototype of the system.
