Glimpse of Major Challenges

  1. There were 280 security requirements to be implemented in the RSE. RSE being first of its kind in the industry, It was a big challenge for us to coordinate with experts from OEM , Tier1 and all other development partners to complete the implementation of the security requirements.
  2. Lately introduced China market requirement to install third party apps brought in a massive change in software architecture. The architecture of the system had to be redesigned in between the development to a hypervisor-based system to incorporate this requirement.
  3. Customizing Android to meet all the OEM specific power management requirements without losing Google compliance demanded in-depth knowledge in the Android framework. Our expert Android architects came up with a power management architecture addressing all power management specific challenges of RSE
  4. RSE being a complex distributed system, routing all logs to a single point in a unified timestamp was a biggest challenge in logging module. We ported DLT for Android and successfully developed a reusable DLT based logger component for Android.
  5. Acsia was entrusted with the responsibility of overall program management coordinating with all suppliers. We devised and followed Project Management process that assures 100 % milestone delivery without missing a single requirement. We formed a separate team and took almost three months to develop a system based on Jira for tracking all activities using required dashboards.
