BIG W.

Large eCommerce digital transformation

BIG W are one of Australia's leading retailers, with a focus on family and value. They have a high traffic website which complements their large in store network. Their online ecommerce was powered by a large, monolithic system, which had a high cost and slow pace of change. A key issue was that system changes for staff in-store impacted customers, and vice-versa.

To remain competitive in market and achieve their scaling goals they wanted to re-architect their systems to decouple dependencies and offer and upgraded ecommerce experience to shoppers.

Problem

BIG W's website, ecommerce site and order management software were powered by a monolithic platform. This was limiting their business in making changes for the different audiences of the platform, including customers, staff and system integrations.

To resolve this challenge, they wanted to re-architect their systems to enabling change to their business without system changes impacting other initiatives and users.

Solution

Upgrowth worked with BIG W to develop a transition strategy to open up their current platform to enable an incremental transformation.

The strategy included

  • producing APIs for their current platform to expose existing business behaviour
  • delivering a new customer-facing website leveraging these APIs
  • extracting essential business functions from the existing platform, enabling development in isolation without impacting BAU processes.

Design System

We developed a refreshed design language and design system with the in-house teams. This introduced brand cohesion, modularity and reuse the product teams had not achieved before.

Problem / Solution fit

The initiative was rolled out to a small trial group of internal staff to ensure that the functions worked as expected and the experience was satisfactory at an early stage. We incorporated feedback from this process, and it allowed stakeholders to build confidence in the outcomes ahead of a full launch.

Product / Market fit

Both the new and old platforms were run for weeks in parallel to ensure a smooth transition. Specific cohorts of customers were introduced to the new experience in an incremental fashion.

This enabled customer feedback to be acquired at scale prior to a full 'go-live' and allowed the complex platform interactions to be monitored with increasing load over time. This approach also built confidence across stakeholders and the wider business.
