各位前輩好，
小弟最近在和同事們討論，對於"大型專案"的定義。
不論是在工作上或面試時，都有意無意會提到，
"有沒有維護或參與過大型專案",
這個時候，就衍生出一個問題，
何謂大型專案？
以下為小弟我在網上找到的對於"大型專案"的定義：
<https://en.wikipedia.org/wiki/Megaproject>.
原文：
According to the Oxford Handbook of Megaproject Management,
"Megaprojects are large-scale,
complex ventures that typically cost $1 billion or more,
take many years to develop and build,
involve multiple public and private stakeholders,
are transformational, and impact millions of people".
[2] However, $1 billion is not a constraint in defining megaprojects,
as sometimes (e.g. in developing countries)
a relative approach is needed because in some contexts,
a much smaller project (such as one with a $100 million budget)
could constitute a megaproject.
Therefore, a more general definition is
"Megaprojects are temporary endeavours (i.e. projects) characterized b
y:
large investment commitment,
vast complexity (especially in organizational terms),
and long-lasting impact on the economy, the environment, and society".
大體上似乎專案的"大型"也就是其規模，是取決於
A: 投入成本。
B: 影響人數
C: 複雜度。
而在Wiki這裡面有提到一些數字：
1. 投入成本： 10億美金
2. 影響人員： 100萬人
所以，如果照著wiki裡的講法，以上二者成立，才能算是"大型專案"嗎？
請各位前輩不吝指教和討論。
