The purpose of the systems analysis phase is to build a logical model of the new system.The first step is(71)，where you investigate business processes and document what the new system must do to satisfy users.This step continues the investigation that began during the(72).You use the fact-finding results to build business models，data and process models，and object models.The deliverable for the systems analysis phase is the（73），which describes management and user requirements，costs and benefits，and outlines alternative development strategies.

The purpose of the systems design phase is to create a physical model that will satisfy all documented requirements for the system.During the systems design phase，you need to determine the（74），which programmers will use to transform the logical design into program modules and code.The deliverable for this phase is the（75），which is presented to management and users for review and approval.
