ANZ Banking Group

Ensayo AI for software requirements and testing

ANZ reported 72% less API testing time with Ensayo AI

WorkingCompany's own claim

Problem

Engineers needed to understand complex banking requirements before writing code. Misunderstandings caused rework, while testing consumed a substantial share of delivery time.

Approach

ANZ developed Ensayo AI with HCL and AWS and had an initial version in production by April 2024. The generative AI tool used banking documentation to help interpret requirements and write automated test scripts. It ran inside an Amazon Virtual Private Cloud.

Results

72%reduction in API testing time reported by ANZCompany's own claim[1]
56%reduction in integration testing time reported by ANZCompany's own claim[1]

Takeaway

The reported gains concerned specific testing stages. ANZ did not report an equivalent reduction in total software delivery time.
