Session:
Function Point Analysis assumes something deceptively simple: that a clear and defensible boundary can be drawn around the application being measured. In modern financial systems, that assumption is increasingly difficult to sustain.
Enterprise banking platforms now operate within ecosystems of payment switches, compliance services, identity platforms, and third party workflow engines that participate directly in business processing while remaining outside the application team’s ownership and control. As functionality becomes distributed across APIs and external platforms, traditional boundary identification and counting decisions become less straightforward.
Drawing from real delivery experience across large scale banking and payment systems at Guaranty Trust Bank, this session explores practical FPA boundary challenges in API dependent financial environments. The presentation focuses on three recurring problem areas: classifying EIFs when external infrastructure performs core business processing, sizing workflow driven functionality where business logic resides in third party BPM platforms, and maintaining counting consistency when regulatory integrations redefine application behaviour over time.
Rather than proposing new rules or workarounds, this session presents principled interpretation approaches grounded in existing IFPUG standards. Attendees will leave with a practical boundary decision framework that can be applied to modern distributed systems in financial services, healthcare, government, and other highly integrated domains where the effective system perimeter is shaped as much by external dependencies as by internal application design.
