When we want to do one thing, we need to judge, to determine whether this thing can do, the conditions may include the ability to determine the adequacy of the matter is legitimate, whether the matter can bring something to yourself and the matter of risk, and so on. Similarly, software engineering, too, developed a software, first we have to determine is that we can not make this software, this software can be made as to whether revenue, this software together illegal, development needs how long and how much resource consumption and so on. This is the content of the feasibility study. The specific content of the feasibility study are as follows:
1. feasibility study in five areas: economic viability, technical feasibility, operational feasibility, legal feasibility, feasibility time, resource feasibility
Step 2. Feasibility study: (1) review the system size and destination
System (2) study currently being used
(3) the export of high-level logic model of the new system
(4) redefine the problem
(5) to the user recommendation method
(6) the recommended course of action to make a crucial decision
(7) draft development plan, write feasibility study report
(8) submitted to higher and Expert Review
3. The purpose of the feasibility study is to use the smallest cost to determine whether the problem can be solved in the shortest possible time. Its purpose is not to solve the problem, but to determine whether the problem is worth solution.
4. Feasibility analysis task: to determine the system's overall objectives and general requirements as well as investment-benefit analysis and progress
5. The method of analysis of the feasibility of: high-level system analysis
