You and your team hit a dead-end while discussing certain design problem. Suddenly, someone brings up one of these magic questions:
How does Facebook do it?
Did you check Airbnb?
Material design has a guideline for that.
I really like how MailChimp does it.
If Twitter does that, there might be a good reason!
While looking at what big tech companies are doing can be a great source of inspiration, that doesn’t mean you should copy their design solutions to answer your design problem. As soon as design decisions are based on “that’s how company X does”, we are ignoring the fundamental role of design in the first place: to improve the product with your user in the center.
