Product design
Product design your developers can build from
UI/UX design for web and mobile products, new or already live, for startups and established businesses.
Every engagement ends with a signed-off design and technical spec, and the same BigIn team can take it straight into development. AI explores options in parallel while our designers decide which direction holds up with real users.
The design system
Five steps, from empathy to test
Every design engagement runs the same five phases, in the same order, whether it is a new product or a redesign of one you already have.
- 01
Empathize
We study your users and your business: who uses the product, what they need, and what is getting in their way.
- 02
Define
We narrow that down to the problems worth solving first and agree them with you, so every design decision has a reason behind it.
- 03
Ideate
Mind maps, brainstorms and mood boards turn those problems into as many approaches as we can find, with AI exploring options in parallel.
- 04
Prototype
The strongest ideas become prototypes, so we can see where each one breaks before anything is built.
- 05
Test
Testing with users confirms what works and what to fix. What we learn goes into the final design and technical spec.
Design artefacts
Mood board, wireframes and prototype screens from a real engagement
Whether you are launching something new or redesigning a product people already use, you get the same five steps and a design your developers can build from.
