viable adj.
释义：able to be done, or worth doing
“viable”是个形容词，它本身的意思是“可以存活的”，常被引申使用表示“可行的” “值得做的”。正如健康的生命才可以存活，好的想法、产品、解决方案才能存活，我们可以用 viable 来形容表示想法、产品、解决方案这一类词，也常可以用它替换 effective, feasible 等词。
例① 在产品设计中，有个概念叫“最简可行产品”，它的英文就是 Minimum Viable Product（MVP），我们可以从它的英文解释中体会一下 viable 的意思：
A minimum viable product (MVP) is a product with just enough features to satisfy early customers and to provide feedback for future product development.
这里的 viable 就可以理解为“satisfy early customers”。如果一个产品可以满足用户的需求，实现盈利，那它就是一个 viable product。
例② 比如星巴克在某一个四线城市开店半年以来，收入明显好于预期。
Starbucks' new store in this fourth-tier city has proved commercially viable.
例③ 从经济角度来看，可再生能源是合适的替代能源。
Renewables are economically viable alternatives.
例④《经济学人》在一月份一篇讲电脑芯片的文章中就用到了 viable：
To keep its design pipeline full of viable new ideas, the firm must constantly forecast the computer industry’s direction.
