After reviewing the documentation from our third-party partner, I facilitated several workshops with our architects and product managers to map the data flow between both sides, determining how lot and batch codes would be submitted, stored, and retrieved.
The resulting data flow diagram became a shared reference point, aligning business and technical requirements, clarifying how third-party systems exchanged and stored the data, and providing a single source of truth for both developers and QA. By visualizing the process, we reduced confusion, accelerated solution design, and ensured FDA traceability standards could be met without disrupting fulfillment operations.
