Executive Story: Next Level Audit: Modernizing Internal Audit for Strategic Relevance at Deutsche Telekom
Jens Duengen,
Vice President, New Ways of Auditing, Deutsche Telekom
As organizations accelerate digital transformation and face increasing complexity, internal audit functions must evolve to remain strategically relevant. In this executive story, Jens Duengen, senior leader within Deutsche Telekom Group Audit, recounts the practical journey of moving internal audit beyond traditional compliance and control, toward becoming an AI-native, value-generating partner to the business.
Initiated in 2021, Deutsche Telekom’s five-year “Next Level Audit” transformation was not merely a technology upgrade, but a comprehensive reimagining of audit’s operating model, culture, and contribution. Jens will discuss how the function shifted from a retrospective assurance mindset to one focused on enterprise impact, agility, and continuous improvement. Central to this evolution was challenging the ingrained preference for perfection, fostering a culture where experimentation, learning from failure, and incremental progress are embraced. The narrative will include candid reflections on both successes and setbacks, such as the lessons learned from an unsuccessful proprietary large language model initiative.
Key takeaways for attendees include:
Leadership strategies for driving cultural change in audit, enabling innovation and experimentation.
Approaches for integrating digitalization, data analytics, and AI to enhance audit products and processes.
Practical lessons on sequencing transformation decisions and building stakeholder confidence.
Insights on aligning audit work with enterprise priorities and delivering assurance that matters to executives and the board.
Reflections on defining the “future auditor” profile and building the necessary skills for sustained relevance.
