SAP S/4HANA Migration Communications That Protect Your Tech Investment
Turn one of the biggest, riskiest change programs on your IT roadmap into an adoption success story. We help project teams build and execute a culture-right stakeholder engagement plan – that's fast, cost-efficient, and owned by you.
Your Window Is Closing Fast
Here's the reality check: ECC support ends in 30 months. 61% of organizations haven't even started their migration yet. Extended support will cost 2-5x more—if SAP even offers it for your landscape.
Late starters face a dangerous combination: rushed technical implementation plus zero time for proper change management. That's how €50M investments become €80M disasters.
Stakeholder Engagement: The Hidden Failure Point in S/4HANA Programs
Technical readiness is vital—but it's not everything. The disasters we see most often stem from people problems: misaligned sponsorship across geographies, local managers who don't see "what's in it for me," employees drowning in parallel initiatives, and system language that never translates into day-to-day impacts.
What Communication Failures Cost
When stakeholders aren't prepared, S/4HANA programs bleed money in predictable ways:
€2.3M average in rework cycles because "hidden" workarounds surface too late
6-month project delays when local sites revolt against imposed changes
€1.8M per 1,000 users in extended hypercare costs
3x normal support tickets flooding your helpdesk for months
The most expensive mistake? Up to 50% of your S/4HANA licenses sit unused because people stick to familiar workarounds and shadow systems.
What's your exposure? With 2,000 users at €75,000 average salary, poor adoption puts €960K to €1.54M at immediate risk—and that's just productivity losses, not counting support costs or unused licenses.
What Success Looks Like Instead
Organizations with structured stakeholder engagement see a different story: executives who confidently repeat clear value messages, local managers who allocate resources because they understand site-specific benefits, and end users who approach go-live with confidence instead of panic.
The results speak:
47% lower hypercare costs,
30% higher adoption rates,
2x faster productivity recovery.
This isn't luck—it's preparation.
THE CHANGE PLAYBOOK:
OUR PROVEN PATH TO ADOPTION
Developed through 15 years and refined across dozens of transformations, our Change Playbook is the foundation of every successful adoption we deliver. It's a complete adoption system that turns complex tech transformations into clear, confident adoption at every level of your organisation.
What the Change Playbook includes:
A battle-tested roadmap: 10 stages that cover the full adoption journey—from understanding your starting point to maintaining long-term usage. Each stage has clear deliverables, decision gates, and success metrics.
Ready-to-deploy tools: Communication templates, learning modules, distribution tools and more. Everything is pre-tested from real implementations and ready to customize.
Adoption tracking: A dashboard that shows usage patterns across teams and features. This helps identify where additional support is needed.
Team enablement: Resources that help your internal teams lead the change process. We work with your people to build capability, not dependency.
The typical Change Playbook journey takes 14-20 weeks, though we adjust based on your organization's size and complexity.
