Engineering Feasibility: A Useful Question

Typically, at some stage in the process of product engineering the design team approach the engineering team and ask for some input on the feasibility of their ideas. I find this question to be a useful prompt for those conversations.

What is the solution we could put together in a day? A month? A year? What are the tradeoffs between them?

I find it useful as, fundamentally, a lot of engineering decisions come down to tradeoffs and this puts that question right at the forefront.
