The brief

It wasn’t broken

Sections were working fine. Nobody used them, which makes for a more challenging brief than making something work since there’s nothing to fix. The task was to design an internal tool worth visiting on one’s own volition.

The constraint

Design system in the wrong file format

Italgas had an extensively thought out design system. It existed in Sketch and deliverable had to be in Figma.

This is why we studied it thoroughly first not to replicate every component but to learn its logic and manually create the missing pieces. Anything else would lead to delivering a product that looks like Italgas but doesn’t behave that way.

The process

Wireframes after the system, not before

That order looks backwards. It worked because the system had already settled spacing, hierarchy and component behaviour, and knowing those answers in advance kept the wireframes from relitigating them.

Decision

Arguing for fewer variants

About 10% of what we needed didn’t exist yet: larger tab sizes, a new size step, the main cards. Each one was a conversation with Italgas’s internal Design Lead, and the conversation was always the same: how do we add this without adding a variant.

We disagreed often, and usefully. A new size in a design system is not a local decision: it propagates. Some of what we proposed was adopted into the system itself and is now used beyond this project.

Result

Where it stands

Delivered and live across the company. Italgas maintains it internally, on a design system that now includes components we drew.

Let’s create

great things.

How do you work?

We keep things transparent and collaborative. We share updates consistently throughout the process, so nothing comes as a surprise. Weekly 1-to-1 meetings keep the work aligned and give space to review what's been done and plan what's next.

Why should I choose Heterochromia?

We work fast and we have an opinion. We don't just ask "what do you want?" and execute. We guide you through the process, challenge your assumptions when needed, and help you get to something better than what you imagined. Damn, we love what we do.

Do you do outsourcing?

Over the years, we have met a lot of talented people. Some of them work with us regularly on projects that require specific expertise.

What timezone are you in?

We are based in Milan, Italy (CET/CEST), but we work with clients in the USA and Japan with full flexibility.
