UI Design, Prototyping

Overseeing a workplace DC pension scheme keeps getting more complex: governance, investments, engagement and member outcomes all demand attention at once, usually across scattered data, with little sense of what matters first.

The brief was to bring all of that into one place. Mercer wanted a single digital dashboard that could turn a scheme's scattered data into clear, comparable insight: showing how members are tracking towards retirement, benchmarking against peers and the market, and keeping governance focused on the decisions that change outcomes.

I designed the product from the data up, shaping each section so it surfaces the insight that matters and points to a clear next step, without turning depth into a wall of numbers. I also designed the motion across the product: every screen animates as it loads and responds, so the data feels considered rather than dropped onto the page.

The whole scheme at a glance

The overview is the front door. It pulls the scheme's headline numbers onto one screen, so the first thing you see is where you stand and what needs attention, before you go digging.

Are members on track?

This is the question that matters most. The readiness view turns "how prepared is our workforce" into a clear measure, then points to the targeted actions that could meaningfully improve the outcomes members are heading towards.

Engagement you can actually measure

Engagement is easy to claim and hard to prove. This view tracks how members genuinely interact with their pension, not just whether they opened an email. It also surfaces a set of featured articles: ready-made prompts and ideas for new ways to engage members, so the screen doesn't just measure engagement, it helps improve it.

Depth where it counts

A clean overview only earns trust if the detail behind it holds up. These screens carry the serious data, ordered so it never becomes a wall of it: simple on the surface, hard-working underneath.

A film to launch it

To launch Mosaic, we produced a promotional video that explains the product and shows it in action. I art directed it, setting the visual direction, pacing and how each screen was framed, and directing the dedicated motion designer who animated it. It's the natural close to the story: everything the dashboard does, in one piece.
