Synopsis
A national postal service modernized its parcel tracking without replacing its core system. Working with BP3, the team externalized more than 1,300 business rules from a COBOL-based platform into IBM Operational Decision Manager, creating a rules layer that can be updated safely and quickly. The system now processes millions of tracking requests daily with an average response time of 15 milliseconds, giving customers real-time visibility and giving the business the agility to keep improving its service.
Tracking at the Speed the Market Moves
Real-time parcel visibility went from novelty to baseline expectation in about a decade. For established postal operators, that shift created a specific engineering problem: the systems handling tracking were built for reliability, not for rapid change.
One national postal service faced exactly this. Its tracking ran on a COBOL-based system that had served the organization well for years. The system was stable and proven, but its business rules were embedded in the code itself, which meant every enhancement moved at the pace of careful legacy development. In a market where private couriers iterate on the customer experience continuously, the constraint was strategic, not just technical.
The team made a deliberate choice: instead of a full rewrite, with all the cost and risk that carries, they would separate what changes often from what changes rarely. BP3 externalized more than 1,300 business rules from the legacy system into IBM Operational Decision Manager. The core system kept doing what it does well. The logic that drives tracking updates moved into a Business Rules Management System where the team can modify, test, and deploy changes safely.
The results are measurable. The system answers tracking requests in an average of 15 milliseconds and processes millions of requests daily. Customers see accurate, timely updates on every parcel. And the postal service can now introduce new tracking capabilities without opening up code nobody wants to touch.
The lesson extends well beyond postal services. Most established enterprises run on systems that are simultaneously too valuable to discard and too rigid to change quickly. Externalizing the business rules is often the highest-leverage move available: it preserves the investment in the core while restoring the ability to move. This postal service did not just fix a tracking problem. It changed how fast it can respond to whatever customers expect next.
