The challenge of this project was not technically impossible: it was technically demanding. Querying 17 independent systems in real time and consolidating the response on a single screen required an integration architecture explicitly designed for speed: parallel queries with partial timeout handling, intelligent response consolidation and a presentation layer that did not wait for the slowest system before displaying available information.
The 700 ms constraint was not an arbitrary requirement: it was the threshold below which the agent perceives the response as immediate, without needing to tell the customer they are “checking the system.” That user experience detail was the design criterion that guided every technical decision in the project.
