Never A Good Plan

The optimistic "let's split the work" phase vs the reality of integration hell. What starts as a clean division of labor ("You do frontend, I'll do backend!") inevitably devolves into a catastrophic electrical storm when the two systems finally meet. Those peaceful smiles transform into thousand-yard stares as they desperately try to connect incompatible interfaces while questioning their career choices. The backend expects XML, the frontend sends JSON, and somehow both are using different authentication schemes. Integration day: where friendships die and Stack Overflow tabs multiply.
