Problem

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 it’s 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.

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.

Upgrowth ran 8 rounds of user testing sessions with initial concepts and designs to gain feedback on crucial parts of the customer experience and validate customer messaging.

User testing continued through design and delivery up until an internal launch with a trial group of staff. BIG W staff are well informed and one of the target user groups and were able to provide constructive real world feedback.

Before launch, we conducted a larger pilot release across Woolworths Group, testing with 2,000+ users to ensure that our product could support a large customer base. This helped provide broader feedback, internal advocacy and clarity around any potential scaling risks for this new customer channel.

From our user testing we identified some key areas of improvement and product enhancements, such as a single step checkout and integrations with native payment providers such as Apple Pay and Google Pay.

Throughout our development cycle, we have continuously iterated upon our existing designs and tested new features with real-world customers. Being that both mobile and web channels are closely related, we’ve been able to action feedback across both customer channels.

Within the first month of launch, the BIG W App had reached the #1 position for shopping apps on the App Store.
