§ 04 — Process

Four steps,
no bullshit.

We keep the method legible: a kick-off, a design sprint, a build sprint, a launch. You always know where we are.

Phase— Week 01
01

Scoping & brief

A one-day workshop to align vision, constraints and scope. We leave with a costed plan.

Phase— Wk. 02 → 05
02

Design & proto

High-fidelity mockups, navigable prototype, design system. Live weekly reviews.

Phase— Wk. 06 → 12
03

Build & integration

Development in testable increments. You see the product grow every week on staging.

Phase— Wk. 13 →
04

Launch & beyond

Go-live, training, measurement. We stay your studio for the iterations that follow.
