Which statement best describes the role of a synchronized release across sites during ECO deployment?

• A. It ensures changes are released independently at each site
• B. It delays deployment until all sites agree
• C. It updates only pilot plant data
• D. It ensures simultaneous rollout across all sites

Answer: (D)

Synchronizing the release across sites is about making the deployment happen at the same time everywhere, so every location switches to the new changes together. This keeps configurations, versions, and compatibility aligned, which reduces the risk of one site running a different build than another and introduces fewer integration surprises. Coordinating a single rollout also simplifies rollback and auditing because you’re tracing a single change window across all sites rather than chasing staggered updates. Releasing changes independently would create drift between sites, delaying fixes and causing inconsistencies. Delaying deployment until all sites agree or updating only pilot plant data misses the goal of a unified, cross-site update.
