Building a new mobile-focused design system that scales to support all user interfaces across React, iOS, and Android platforms.
Product Designer, Design Systems
As the second designer to come in and support design systems, my focus gradually grew from designing new components and assets to include the creation of design tokens, creating a11y standards, and adding clear information architecture to our design system; all while working closely with lead feature designers and engineers to align DS with feature needs.
1 Product Design Lead, 2 Product Designers
1 Product Manager, 1 Project Technical Manager
2 Platform Architects, 4 React Developers
2 iOS Developers
1 Android Developer
To successfully deploy a complete app redesign, product designers and engineers required a fully designed, documented, and built design system across native iOS and native Android (and we also needed to update the existing React web design system).
The work was really expedited by the support of the entire product design team. As we were a group that had just come together, taking over previous contractor work, there was an understanding that DS would play an integral role in defining the complete redesign work from the start - without that buy in, it would have been much harder for design system work to get anywhere.
To do so, the DS team sought to understand the loop from the perspective of different key stakeholders. Qualitative 30 min. interviews were conducted with:  Product Managers,  Designers,  Web Developers,  iOS Developers,  Android Developers and  Content Manager.
Through understanding our own system, a lot of problems began to uncover themselves. For example, it became clear that because not everything was built, there was a lot of wasted time between engineers and designers trying to juggle what they could and couldn't use.
Even doing a preliminary inventory of DS components painted bigger picture of what the system could and couldn't provide.
There was also a lack of documentation parity between what was provided in design libraries and in documentation of the built components. Because of this lack of parity, even if members of the design system team communicated to our product design partners what was available, the same information didn't hold true when passed down to engineering.
Through research, we identified three main problems we wanted to focus on creating solutions for:
1. Piecemeal availability was hindering progress.
2. Existing DS design and developer documentation was fragmented.
3. Components and assets weren’t aligned with feature team needs and use cases.
Our metrics of success for solving these problems were as follows:
1. Does the mobile DS improve feature launch velocity?
2. Has there been an increase in code adoption?
3. Is there an improvement in # of Figma component inserts?
I structured my design work to focus on three main objectives:
1. Design DS components more aligned with feature team needs.
2. Work with developers to create more dev-oriented design documentation.
3. Articulate overlaps in designer-engineer workflow processes and structure.
Lists were used in some capacity by different designers, all working with their own version. As pages such as Trading and Settings were built, they were going to rely heavily on Lists and the component needed to be thought through from end to end.
Compared to Lists, Headers were first defined by redesign designers. However, people were still using individual header components throughout flows, and as a global navigation component, Headers needed to be fully realized in order to be a functioning design system asset.
By gathering use cases, I was able to understand what exactly helps shape BlockFi's needs out of a List component (these are only a few).
With Headers especially, it was key to identify all the properties that would make up a scalable component from the design side. Some of these would include:
Landing vs. Scroll Interactions
Components Available vs. New
iOS + Android Native prebuilds
Dark Mode Considerations
Spacing, Padding Adjustments
Icon Button Interaction Overrides
Changes for 320px, 375px, 360px
When building, in order to reflect how components would be used and built, both components followed an atomic architecture to support scalability and to develop parity between components in Figma libraries and components in the repositories.
Different components require different types of documentation. For example, Lists were more easily built through understanding variant states, while Headers needed more documentation around on-scroll behavior.
By documenting a lot of the accessibility requirements that we wanted to meet at the very beginning, the DS team signaled that a11y was a non-negotiable consideration when building components.
Covered in documentation: Voiceover Choreography, Large Screen Viewers, Dynamic Text Scaling, Color Contrast Checks
Half of design systems is actually getting things built, so as a design system team we looked to embed our design work as closely as we could to engineer workflows.
For example, we reorganized and articulated the full DS workflow for designers and engineers to align together on an agreed process.
Instituting our project tracking systems in JIRA helped us align our outstanding tickets and tasks to better align and keep track of parallel progress with components in development (as opposed to previous ad-hoc tracking in Google Docs).
In line with the Product QA step we aligned on, testing for development was done through Storybook for React Web, Testflight instances for iOS and Android APKs for Android.
Ex. WIP for Lists being built by the React team, demo'd through our staging Storybook.
As new redesign components are being merged, we revisited the metrics we set out for Mobile 2.0, keeping in mind that our benchmark is previous feature design releases that went out without Mobile DS support.
A willingness to listen and developing open lines of communications created a more resilient and flexible system.
Taking the time to workshop blockers allowed teams to arrive at a north star vision, solutions for tomorrow and solutions for today.
The systems community is moving towards dynamic layouts and tokens simultaneously, which brings design and development closer than ever before.
Giving design stakeholders autonomy and ownership allowed for a closer working, living, and breathing system.
Also, nested instances are 💯
