01 / Project overview

The
product

A web app for sales ranking and team management at Nissan dealerships.

SERNISSAN gathers in one place the results and key indicators of Sales, After-sales and Quality teams: team monitoring and ranking, monthly goals, feedback scheduling and notifications.

As a solo freelance designer, I led the end-to-end redesign of the product, from the analysis of the legacy system to the prototypes of the new one.

Along the way, I worked closely with the development team and with the business leaders, the client responsible for rolling the product out to the dealerships.

02 / The challenge

Bringing teams
back on board

Renewing a system teams had stopped engaging with.

Dealership teams were barely engaging with the previous system, and parts of the sales routine still lived in spreadsheets.

The redesign had to make it friendlier and more intuitive without losing the depth of a performance tool: indicators, goals, weights and rankings across a large network of dealerships, from country down to each store.

03 / Design process

From legacy
to new product

Understanding what existed before designing what should come next.

I started by analysing the legacy system alongside the new requirements and features. Then I worked on the interaction flows, and finally created a design system and prototyped the main flows and screens.

01Analysis

Review of the legacy system and mapping of the new requirements and features.

02Interaction flows

Navigation flows and information architecture for the main tasks.

03Design system

A component library to keep a dense, data-heavy interface consistent.

04Prototypes

Navigable prototypes of the main flows and screens, validated with stakeholders and iterated.

04 / Inside the product

Performance,
month by month

Each month, managers pick 3 key indicators and 3 commitments for their teams to focus on.

The product follows that cycle: managers choose indicators, weights and goals, team results feed a monthly scoreboard, and feedback meetings close the loop.

01Performance scoreboard

Monthly results by area and role, with points per indicator and an updatable ranking.

02Indicators & goals

A library of indicators with weights and targets, plus custom indicators per dealership.

03Management calendar

Scheduling of feedback meetings and key dates with the team.

04Team

Leaders and team members per dealership, with areas, roles and access profiles.

05Dealer hierarchy

Navigation across country, division, sector, group and dealership.

06Guides

Built-in materials, such as a glossary of the terms teams use every day.

05 / Design system

Built for
dense data

A consistent language for a data-heavy product.

I created a design system for the new SERNISSAN, with components and patterns for tables, filters, forms and modals, keeping dense screens readable and consistent across modules.

06 / Outcomes

Live in
dealerships

A friendlier system, in daily use.

The new SERNISSAN is live in Nissan dealerships, rolled out to the network through training sessions.

The project had no budget for deeper testing, but adoption speaks for itself: today the system runs in 210 dealerships across Brazil, with more than 3,600 users and over 2,500 performance scoreboards.

The platform was designed to support dealerships across all of Latin America; so far, it has been rolled out in Brazil.
