SSADM 傻瓜书
这个问题可能看起来很愚蠢，但在学习新东西时我需要有一个清晰的想法:)
在SSADM中，我们是否必须对“可行性”（Stage0）进行全面的研究？在对业务进行“调查”（第一阶段）之前，我们如何才能了解可行性？
无论如何，Stage0 的实际预期是什么？
谢谢。希望有人能阐明这一点。
this question might look dumb but I need to have a clear idea when learning about something new :)
In SSADM, do we have to do a comprehensive study about the "feasibility" (Stage0)? How can we get an idea about the feasibility before even performing "investigation" (Stage1) about the business?
What is actually expected in Stage0 anyway?
Thanks. Hope someone would shed a light on this.

我目前无法获得我的参考资料，所以这是凭记忆 - 我认为可行性阶段是为了使项目启动 - 为什么人们应该投入资源进行调查。因此，当他们谈论可行性时，报告的内容可能涵盖的是对问题的广泛陈述；为什么这是一个问题；为什么系统解决方案看起来像是解决问题的方法；谁来支付费用？谁在赞助它，谁将从中受益。
根据定义，在开始工作之前不可能对可行性进行全面的研究，而是我认为可行性图画描绘了如果该项目继续进行可能会发生的情况 - 如此粗略的描画而不是详细和详细的综合的。
本质上，可行性阶段是回答以下问题：“我们为什么要费心去做这个项目；如果我们费心去做这个项目，我们是否认为我们有能力做它。”
My references are not available to me at the moment so this is from memory - I think the feasibility stage is about getting the project off the ground - why should people commit resources to even an investigation. So when they are talking about feasibility, and the contents of the report things that are likely to be covered are a broad statement of the problem; why it is a problem; why a system solution looks like the way to go to solve the problem; who will pay for it; who is sponsering it and who will benefit from it.
By definition, it is impossible to do a comprehensive study of feasibility before getting into the work, but rather I think of a feasibility picture as painting a picture of what might be if this project were to go ahead - so broad stroke rather than detailed and comprehensive.
In essence the feasibility stage is answering the questions "why should we bother with this project; and if we are bothered to do this project do we think we are capable of doing it.
