Accelerated analysis approaches emphasize the construction of  （1）  to more rapidlyidentify business and user requirements for a new system. As an accelerated analysis technology,（2）  reads the program code and automatically generates the equivalent system model, andthe code can be obtained from  （3） . All system analysis approaches require some form of（4）  which includes those techniques to be used to identify or extract system problems andsolution requirements from user community.  （5）  is a classical set of techniques used tocollect information about system problems, opportunities, solution requirements, and priorities.
