When we talk about validating feasibility, the engineers are really trying to answer several related questions:
I don't want to scare you. With most product ideas that your engineers review in discovery, they will quickly consider these points and simply say “No problem.” That's because most of our work is not all that new, and engineers have usually built similar things many times before.
However, there are definitely ideas where this is not the case, and some or many of these questions can be very difficult for the engineers to answer.
One very common example right now is that many teams are evaluating machine‐learning technology, considering build/buy decisions, and assessing whether the technology is suitable for the job at hand—and, more generally, trying to understand its potential.
Here's some very practical and important advice for you to consider. Holding a weekly planning meeting where you throw a bunch of ideas at the engineers—and demand they give you some sort of estimate ...
