资料：People differ greatly in their readiness to try new products. In each product area，there are“consumption pioneers”and early adopters. Other individuals adopt new products much later. After a slow start，an increasing number of people adopt the new product.
The five-adopter groups have different values. Innovators are venturesome-they try new ideas at risk. Early adopters are guided by respect-they are opinion leaders in their communities and adopt new ideas early but carefully. The early majority are deliberate-although they rarely are leaders，they adopt new ideas before the average person. The late majority skeptical-they adopt an innovation only after a majority of people have tried it. Finally，laggards are tradition bound-they are suspicious of changes and adopt the innovation only when it has become something of a tradition itself.
Which group adopts new ideas before the average person？A.Early adopters
B.Innovators
C.The early majority
D.All above

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) (请作答此空 ) is a team-based technique that speeds up information systems development and produces a functioning information system. The approach consists of several phases. The () combines elements of the systems planning and systems analysis phases of tbe SDLC.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.Object-oriente development
面向对象开发
B.Model-driven development
模型驱动开发
C.RapiD.application development
快速应用开发
D.Commercial Application package
