As a Senior Risk Manager at a large, global financial institution, you've been tasked with redesigning the firm's enterprise-wide stress testing framework. The objective is to evolve stress testing from a purely compliance-driven exercise (e.g., CCAR/DFAST) into a truly **strategic** tool that informs capital allocation, business strategy, and risk appetite setting. Elaborate on the key challenges you would encounter in implementing this enhanced framework, and propose a comprehensive approach to address these challenges. Your discussion should focus on integration, model governance, data quality, scenario design, and how to translate stress test results into actionable business insights, particularly considering macro-financial linkages and potential second-order effects.

作为一家大型、全球性金融机构的高级风险经理，您被指派重新设计公司的全企业范围压力测试框架。这项任务旨在将压力测试从纯粹的合规驱动（例如，CCAR/DFAST）转变为一个真正具有**战略性**的工具，用于指导资本配置、业务战略和风险偏好设定。请详细阐述您在实现这一增强框架时将遇到的关键挑战，并提出一套全面的方法来解决这些挑战，重点关注集成性、模型治理、数据质量、情景设计，以及如何将压力测试结果转化为可操作的业务洞察，尤其要考虑到宏观金融联动和潜在的二阶效应。
