Situation

With the acquisition of Trustpower’s retail business by Mercury in May 2022, a significant endeavour was initiated to unite all customers under a single brand and transition them to a unified enterprise software system for customer billing and management. The Retail Integration Program was established with a strong focus on maintaining the highest standards of quality control.

With quality control an essential aspect of the Retail Integration Program, quality assurance specialists were engaged to support the software test planning and test delivery to enable Mercury to migrate hundreds of thousands of customers in batches to the single system with full confidence.

“Migrating 300,000 customers along with historical data is a big project. Assurity’s knowledge sharing has helped us accelerate the process.”
