These people are usually product managers (who build the vision and strategy for a product), designers (who design the product), and engineers (who will evaluate the technical feasibility of the idea and build it). The insights you will share and recommendations you will make will be driving the work of the whole team (product managers, designers, and engineers).
So it comes as no surprise that you need to learn how to persuade people why they should listen to your ideas and why they matter in the first place.
