The provided document outlines the Resilience Trust Engine (RTE), a proactive framework designed as an "enterprise Digital Immune System" for financial services to enhance IT resilience and address complexities in digital transformation. It describes the RTE's core architecture, emphasizing an AI Objective Arbiter that orchestrates specialized software tools rather than creating code, and its alignment with Stafford Beer's Viable System Model (VSM). The text details a six-stage Digital Maturity Lifecycle, explaining how each stage leverages specific technologies and the AI Arbiter to embed security, compliance, and stability from development to deployment. Ultimately, the RTE aims to reduce technological risk, boost developer productivity, ensure regulatory compliance through a data-driven audit trail, and integrate seamlessly with existing IT Service Management (ITSM) frameworks by transforming governance from reactive to continuous. The document concludes with a phased implementation roadmap to realize these benefits and achieve "enterprise homeostasis."
