Why Automation Fails at the Interfaces, Not the Logic
Automation problems rarely begin in the logic itself. They begin where assumptions meet reality: at the interfaces between systems, files, permissions, timing, and people. In pilots, these edges are often invisible. In production, they are usually the first place where things start to break. 1. Logic Is Usually Not the First Problem When automation fails, teams often assume the core logic must be wrong. In practice, that is rarely the first issue. The calculation, transformation, or decision logic often works exactly as intended in isolation. What breaks are the surrounding conditions: a file arrives late, a field changes format, a permission is missing, or a downstream step behaves differently than expected. Logic usually survives testing. Interfaces are where production starts to expose reality. 2. Interfaces Are Where Assumptions Collide Interfaces are rarely just technical connectors. They are agreements about format, timing, availability, permissions, and meaning. One system ...
