Feasibility should be measured throughout the life cycle of system development. The
scope and complexity of an apparently feasible project can change after the
initial problems and opportunities are fully analyzed of after the system has been
designed. Thus,a project that is feasible at one point may become infeasible later .
The first feasibility analysis is conducted during the( ) . The( ) represents a major
feasibility analysis activity since it charts one of many possible implementations
as the target for systems design. ( )is a measure of how well the solution will work
in the organization. It is also a measure of how people feel about the system. When
it is determined in the later stages of the system life cycle, ( ) is often performed
with a working prototype of the proposed system. This is a test of the system's user
interfaces and is measured in how easy they are to learn and to use and how they support the desired productivity levels of the users. Economic feasibility has been defined as a cost-benefit analysis.The ( ) technique is a simple and popular method for determining if and when an investment will pay for itself.

参考答案: BDACA
可行性的判定贯穿于系统开发的生命周期。一个明显可行的项目,在全面分析了初始问题和机会或系统设计后,其范围和复杂性会发生变化。因此某- -时刻可行的项目在此后可能会变得不可行。第一次可行性分析在初始调研阶段进行。由于要绘制多个可能的实现方案之一作为系统设计的目标,决策分析阶段表示一个主要的可行性分析活动。操作可行性是对解决方案在企业中工作效果的度量,它也是衡量人们对于系统的感受。当它在系统生命周期后面的阶段被确定后,经常会用一个建议系统的工作原型进行可用性分析。这是对系统用户界面的一种测试,它通过系统如何易于学习和使用及系统如何支持用户所期望的生产力水平进行衡量。偿还分析技术是一种简单流行的方法用于确定是否及何时将收回成本。
