Big W logo
BIG W is one of Australia's leading retailers, with a focus on family and value. They have a high-traffic website where the majority of users are using mobile devices.



To support the increasing desire for shopping on-the-go and staying connected to the BIG W brand, it was clear that BIG W required a mobile application to appeal to their large customer base.

The opportunity

To remain competitive in an increasingly mobile market and the rising surge of online shopping, BIG W required a native application that customers could use to purchase products on-the-go and stay connected to the BIG W brand and its services. With competitors such as Amazon, Target and Kmart having a strong mobile presence, the need for a mobile application has never been more apparent.

The solution

To respond to the urgent demand for a customer-facing mobile application, Upgrowth put forward a roadmap to the BIG W team prioritising features that were critical to the user experience for the initial launch, and features that could be deployed in future releases.



The outcome of this process was a clear launch scope focused on customer experience opportunities and a roadmap for subsequent releases. This allowed us to identify dependent systems and data required to support changes required in existing systems and infrastructure to ensure a smooth launch.

Design System

To reach market readiness as soon as possible, it was clear that our design and development teams needed to be closely aligned to produce components and screens efficiently to respond to rapid change and user feedback. To accelerate the launch and ongoing delivery of the mobile app, Upgrowth defined and delivered a refined design system.



The design system introduced design tokens, component-based design, signposting, annotation for accessibility and other non-visual experience requirements. Our process for design system change included a tight feedback loop with user testing and a lightweight developer handover process. The basis of this process is informing the BIG W and Woolworths Group way of working going forward.
