Casus Belli Engineering describes how technical failures in software organizations become pretexts to replace working systems with preferred technologies. When features fail, stakeholders lose confidence in entire systems, demanding visible action rather than root cause analysis. This creates pressure to assign blame, leading to the selection of scapegoats—typically foundational components—that bear collective guilt.

The scapegoat mechanism follows a predictable pattern: failures occur, someone identifies a foundational component as the culprit, and it's ritually condemned. The proposed replacement aligns suspiciously with the accuser's preferred technologies. The actual causes—poor integration, inadequate testing, operational neglect—become eclipsed by a narrative that indicts the foundation wholesale.

Psychologically, this appeals to individuals who substitute narrative coherence for causal analysis. They combine motivation to identify targets, rhetorical facility to construct convincing stories, and insecurity that demands external validation. This transforms advocacy into destruction, as the scapegoat must die so the accuser's worldview can be consecrated as the remedy, fundamentally reshaping technical landscapes without merit.
