A variety of tools is available to help the analyst to discover the users&39; true needs. These tools are grouped into three broad techniques that are based on the degree of change anticipated in the to-be system - Business process（ ）is used when the basic business Requirements outlined in the system request focus on employing computer technology in some aspect of the business process. Two popular activities used in the technique are（ ）. Business process（ ）means that the basic business requirements target moderate changes to the organization&39; s operations. （ ）are three popular activities in the technique. Business process（ ）means changing the current way of doing business and making major changes to take advantage of new ideas and new technology.

System analysis is traditionally done top-down using structured analysis based on（ ）. Object-oriented analysis focuses on creation of models. The three types of theanalysis model are（ ）. There are two substages of object-oriented analysis.（ ）focuses on real-world things whose semantics the application captures. The object constructedin the requirement analysis shows the（ ）of the real-world system and organizes it intoworkable pieces.（ ）addresses the computer aspects of the application that are visible tousers. The objects are those which can be expected to vary from time to time quite rapidly.
