Fixes that used to take two weeks now ship in hours.
Vattenfall was running three separate mobile teams with their own systems, slow release cycles, and platform-specific issues. We unified everything into a single platform, so updates ship faster, bugs get fixed immediately, and teams no longer wait weeks to respond to problems.

Before Cermus, fixing a bug meant waiting two weeks for the next release. After, we could push fixes in between.
A production bug used to sit in queue for two weeks before a fix could ship. Three separate mobile teams ran on three release cycles, three codebases, three review processes, and a feature launch meant lining up three calendars. The cost: out-of-sync releases, platform-specific bugs, fragmented user experience, and slow response when issues hit production.
Before
After
From three queues to one. Fixes that used to take two weeks now ship in hours.
The unified platform let Vattenfall scale operations while maintaining the high security standards required for energy infrastructure. Development teams were consolidated onto a single system, deployment processes became significantly more efficient, and issues could be resolved without waiting for full release cycles.
The biggest shift was in speed of response. Where a production bug used to mean waiting two weeks for the next release, fixes can now ship in between. That changed how the team works, and how quickly customers see improvements.
