Svenja Sass is a senior program leader for large-scale digital transformations in DAX companies, with a focus on complex ERP/CRM landscapes and AI-enabled platforms. She has led international hybrid teams of 70+ people across onshore, nearshore and offshore locations – often stepping into programs that are already in trouble and bringing them back on track.

🔧 Delivery & Architecture
Svenja specializes in integrating different delivery models within one program – for example, combining waterfall ERP projects with agile CRM implementations under a single testing and release strategy. She designs pragmatic SIT and UAT approaches across multiple vendors and systems and is known for turning chaotic testing phases into structured, end-to-end quality gates that actually work.

👥 Leadership & Culture
Her work sits at the intersection of delivery, leadership and culture. Drawing on her podcast conversations and project recovery experience, she talks openly about what really makes or breaks projects: clarity of roles, honest escalation, and the ability to communicate change instead of just “managing” it. She has developed practical tools such as a “project user manual” for roles and expectations, and a one-page leadership guide for critical project phases.

🎙️ Keynotes & Thought Leadership
On stage, Svenja is known for her candid, concrete style – no buzzword bingo, just real stories from the field. Her keynotes include:

“Too Busy to Improve” – what high-performing executives do differently in transformation.

“Waterfall + Agile, One Program, One Go-Live” – integrated testing in mixed delivery setups.

“From Firefighting to Ownership” – how to lead hybrid engineering teams that deliver.

“Agentic AI – Adapt or Lose” – why office jobs as we know them are going away and how to stay relevant.

🧭 Focus
Across all her work, Svenja’s core theme is simple: stop being too busy to improve. She helps organizations move from permanent firefighting to focused, value-driven delivery by aligning strategy, governance and engineering culture so digital projects don’t just look good on slides, but actually land in the real world.
