[单选题]During the systems analysis phase, greater user involvement usually results in better communication, faster development times, and more satisfied users.There are three common team-based approaches that encourage system users to participate actively in various development tasks.1) () is a popular fact-finding technique that brings users into the development process as active participants. The end product of the approach is a requirements model.2) () is a team-based technique that speeds up information systems development and produces a functioning information system. The approach consists of several phases. The (请作答此空) combines elements of the systems planning and systems analysis phases of tbe SDL C.Users, managers, and IT staff members discuss and agree on business needs, project scope, constraints, and system requirements. During (), users interact with systems analysts and develop models and prototypes that represent all system processes, outputs, and inputs.3) () attempt to develop a system incrementally by building a series of prototypes and constantly adjusting them to user requirements. A.requirements planning phase 需求计划阶段 B.business process modeling 业务流程建模
A.business process improvement
B.业务流程优化
C.scope definition phase
D.范围定义阶段

[单选题]During the systems planning phase. a systems analyst conducts a（ ）activity to study the systems request and recommend specific action. After obtaining an authonzation to proceed. the analyst interacts with(请作答此空) to gather facts about the problem of opportunity, project scope and constraints, project benefits, and estimated development time and costs. In many cases. thesystems request does not reveal the underying problem, but only a symptom. A popular technique for investigating causesand effects is called ( )The analyst has analyzed the problem or opportunity. defined the project scope and constraints, and performed ( )to evaluate project usability, costs, benefits, and time constraints. The end product of the activity is ( ) .The main content must include an estimate of time .staffing requrements, costs, benefits, and expected results for the next phase of the SDLC A.system users
A.system owner
B.managers an
C.users
D.business analysts

D.computer design and detailed design

[单选题]The most expensive phase of life cycle costing is （ ） .
A.Termination
B.Applied research
C.Production
D.Operations and support

[单选题]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.
A.systems planning phase
B.systems modeling phase
C.systems analysis phase
D.systems design phase
