Every decision is a 3 legged stool.
Design. Engineering. Product.
It’ll start when the PM calls a meeting.
I outline the business problem and a few options. I focus on the problem we need to solve.
The meeting gives design and engineering a chance to ask questions. And to help shape the decision.
The engineering manager can speak to tech feasibility. The designer can speak about the user.
Sometimes, I don’t propose any solutions at all. I don’t want to bias the group.
Then we can come to a solution together.
