FAQ
What does a product design agency do?
It turns a product idea or an existing product into tested flows and interfaces: research, information architecture, prototyping, UI design and often a design system for your engineers.
Should we hire an agency or build an in-house design team?
An agency gives you a senior team immediately, which suits a launch, a redesign or a hard problem. An in-house team is better for continuous improvement once the product direction is settled. Many companies use an agency first, then hire.
How do product design agencies work with engineers?
The best ones share files, components and documentation in the tools your engineers already use, and stay involved during the build. Ask to see a handoff from a past project.
How do we measure whether the redesign worked?
Agree on two or three metrics before design starts, such as activation, task completion or support tickets, and measure them before and after launch.
