During COVID-19, Australia was facing a massive job crisis. Services Australia, a government-run welfare agency, saw a considerable spike in welfare applications. This eventually led to a complete breakdown of their system. In their search for a feasible solution, Services Australia came across the concept of composable commerce. Though this application was niche then, it quickly became a silver lining. By integrating MACH architecture, Services Australia could build a resilient, flexible and scalable composable commerce platform that became a safety net for the citizens. With the deployment of voiceprint technology and digital assistants, the agency could cater to 1.2 million users and orchestrate quick responses. This goes to show how scaling an outdated platform with MACH can make a positive difference in many lives. The rise of composable commerce also marks a radical shift in the way digital and eCommerce platforms are functioning today.
