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.
