Mallcomm - design system

Saving over £84,000 in annual development costs with a scalable design system

TLDR: Full case study coming soon!

Background:

As Mallcomm rapidly scaled, inefficiencies in design and development handoffs added up to 24 extra days to project timelines, risking revenue loss and delaying product releases. The business recognised a critical need to unify design practices to keep pace with growing demands while maintaining high standards for product quality and user experience.

Role & Responsibilities:

As the Lead UX Designer on this initiative, I spearheaded the end-to-end creation of a scalable design system from research through implementation. I partnered with design, product, and development leads, guiding a cross-functional team of 7. My responsibilities also included establishing governance for scalable updates and managing stakeholder buy-in.

Process:

I implemented a design system rooted in atomic design principles, creating a comprehensive pattern library and design tokens to drive consistency across design and development teams. Workshops, iterative feedback loops, and usability testing sessions were held to validate each component, ensuring the design system aligned with both business needs and technical constraints. A critical focus was on accelerating handoffs and decision-making to streamline workflows.

Outcome:

The implementation of the design system resulted in a 72% reduction in prototyping and usability testing time, enabling faster iterations. Development time decreased by 18%, which cut release cycles by an average of 14 days, saving the company over £84,000 annually. The standardised design components also improved overall resource utilisation, allowing teams to make faster, more informed decisions.

Pursuit - Mobile Point of Sale

Increasing average in-store sales by 17% with a line-busting mobile POS system

TLDR: Full case study coming soon!

Background:

Retailers experienced declining sales due to long checkout lines and limited POS flexibility, leading to poor customer engagement. The goal was to develop a mobile Point of Sale (mPOS) system that allowed sales associates to assist customers anywhere in-store. This would streamline checkout, enhance customer experience, and align with the company’s digital transformation strategy to boost sales and operational efficiency.

Role & Responsibilities:

As the Senior UI/UX Designer and Developer, I managed the design lifecycle from research to implementation, leading cross-functional collaboration with designers, developers, marketing and technical support. I aligned design with business goals, mentored junior designers, facilitated communication across teams and managed agile sprints, to resolve technical challenges.

Process:

I led user research to uncover checkout inefficiencies and customer pain points. Insights informed the design of a streamlined mPOS system with intuitive features including quick item access and upselling prompts. I coordinated weekly workshops with stakeholders and developers, iterating based on feedback and overcoming technical challenges, ensuring the design was both scalable and aligned with business and user needs.

Outcome:

The mPOS system increased average in-store sales by 17%, transaction values by 8%, and improved staff productivity by 35%. Customer satisfaction rose, reflected in a 28% increase in NPS. The system's scalability supported long-term growth across multiple store locations, delivering significant business impact aligned with the company’s digital transformation goals.

Mallcomm - user Onboarding

Growing user activation rates by 37% through an efficient and tailored onboarding experience

TLDR: Full case study coming soon!

Summary:

The Mallcomm app faced high user drop-off during onboarding and low feature engagement, impacting retention. The project aimed to simplify onboarding, improve feature discoverability, and enhance long-term user engagement, aligning these efforts with business goals. The overarching objective was to increase app retention and drive greater value for shopping centres by improving the app experience and boosting client promotional content interaction.

Team:

As Lead Product Designer, I oversaw the design process, from user research to final delivery. My responsibilities included crafting strategy, leading cross-functional collaboration, executing designs, and managing project timelines. I implemented Single Sign-On (SSO) to streamline onboarding, integrated personalisation to enhance engagement, and ensured that design solutions aligned with business and technical requirements through regular reviews and workshops.

Responsibilities:

User research revealed that onboarding complexity caused drop-offs, and poor navigation hindered feature engagement. I redesigned the onboarding flow, reducing screens from 12 to 6 with SSO and introduced a contextual onboarding experience. I facilitated cross-functional collaboration, led design sprints, and ensured data-driven iteration through usability and A/B testing, continually refining the app post-launch based on user interaction metrics.

Outcome

The redesign reduced onboarding time by 61% and increased completion rates from 72% to 95%. User activation grew by 37%, and time spent on promotional content tripled. Improved feature discoverability and personalisation also boosted user satisfaction and tenant participation. Continuous iteration post-launch resulted in a further 12% retention increase, driving significant business impact and long-term success for the app.
