Case Study: UK Government’s Data Communications Company averts smart meter rollout disruption with Expleo retrofit regression testing

How retrofit testing averted major disruption to smart meter rollout

The UK government’s Data Communications Company faced a major challenge ensuring its smart meter release 4.0 complied with a new directive. With 300 changes to implement and incomplete testing, the release risked significant disruption to the national rollout. Expleo was engaged to address these quality assurance risks.

Expleo implemented a retrofit regression testing solution to assess the impact of all the changes. This process identified 35 defects, including a high number of severe issues, which were then fixed. This allowed the client to hit a critical release deadline on time, avoid launching an inferior product, and maintain customer satisfaction.
