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.

可行性的判定貫穿于系統開發的生命周期。一個明顯可行的項目,在全面分析了初始問題和機會或系統設計后,其范圍和復雜性會發生變化。因此某- -時刻可行的項目在此后可能會變得不可行。第一次可行性分析在初始調研階段進行。由于要繪制多個可能的實現方案之一作為系統設計的目標,決策分析階段表示一個主要的可行性分析活動。操作可行性是對解決方案在企業中工作效果的度量,它也是衡量人們對于系統的感受。當它在系統生命周期后面的階段被確定后,經常會用一個建議系統的工作原型進行可用性分析。這是對系統用戶界面的一種測試,它通過系統如何易于學習和使用及系統如何支持用戶所期望的生產力水平進行衡量。償還分析技術是一種簡單流行的方法用于確定是否及何時將收回成本。
