From Reactive to Proactive: How Georg Sahm GmbH & Co. KG Transformed Service into a Strategic Growth Engine with Si2 Group

At the SLN Summit in February 2026, Martina Krengel of Georg Sahm reflected:
“What makes me most proud is not only the contracts we have signed, but the change in mindset within SAHM. Service today has a completely different standing in our company. There is acceptance, transparency and measurable performance. The key was ownership. Si2 supported us at exactly the right moments — especially in contract design and service sales development — but the responsibility stayed with us. That combination made the difference.”
Why Top Service Leaders Choose Coaching-Sparring

How Si2’s Intensive Sparring Programmes Help Service Directors Navigate Complexity, Build Confidence, and Deliver Sustainable Impact
Over the last 24 months, Si2 has seen a sharp rise in demand for what many Service Leaders loosely refer to as coaching—and just as often as sparring. While the terminology varies, the underlying need is remarkably consistent.
Service Directors and VPs are operating in an environment of growing complexity:
• Digitisation and IoT initiatives moving faster than organisational capability
• Talent and knowledge gaps driven by retirements and attrition
• Increasing pressure to monetise services while protecting the installed base
• Heightened scrutiny from senior leadership on service profitability, growth, and resilience
In this context, many high-performing Service Leaders reach a similar conclusion: they need a trusted external partner—not to tell them what to do, but to help them think better, faster, and with greater confidence.
This is where Si2’s Coaching-Sparring offering comes in.
The Road to High-Performing Service Teams

Every Service Director and Service VP wants a high-performing team—one that executes reliably, collaborates cross-functionally, and drives continuous improvement even under pressure. But in industrial markets, where service organisations sit at the intersection of engineering, commercial, and operational realities, high performance rarely emerges spontaneously.
Leaders love to claim they have created high-performing teams, but few truly understand the underlying mechanics that make sustained high performance possible.
Fortunately, decades of organisational research give us a clear blueprint on what leaders can do to create the environment for performance through processes, culture and metrics. When combined with modern insights into human performance and energy management, in other words what enables individuals to thrive rather than burnout, we can begin to offer service leaders a practical framework for creating predictable, resilient, high-performing teams.
