Multi-vendor Service Integration (SIAM)
One accountable partner coordinates all your IT suppliers, so services work end to end, contracts are followed up and nobody can point at someone else.
Is this for you?
You might need this if…
When something breaks, suppliers blame each other and your team ends up coordinating the fix.
Every supplier reports green on its own SLA, yet users still experience poor service.
Your IT department spends more time managing contracts and suppliers than improving services.
You plan to change a major supplier and worry about what will fall between the gaps during the switch.
What we deliver
What it covers
One point of accountability
We act as the service integrator across your IT suppliers, coordinating incidents, changes and problems that cross supplier boundaries. You deal with one party, and suppliers work to a common set of rules.
Supplier governance and performance
We set up governance forums, align SLAs and follow up supplier performance against contracts. Underperformance is spotted early and handled with facts, not opinions.
End-to-end service management and reporting
We define common processes and integrate data from suppliers’ tools into one view of each business service. Reports show the service users actually get, not just each supplier’s part.
Transition and exit management
We plan and run moves between suppliers, including knowledge transfer, data handover and parallel running. Changing supplier becomes a controlled project rather than a risk to operations.
Our approach
How we work
01
Map
We map your suppliers, contracts, service levels, interfaces and the current pain points between them.
02
Design
A SIAM model with roles, processes, governance forums, end-to-end service levels and data flows between tools.
03
Integrate
Onboarding of suppliers to the common processes, tool integrations and reporting, with collaboration agreements in place.
04
Govern
Ongoing service integration, performance reviews and continual improvement across all suppliers.
Best practices
What we bring to every engagement
Measure the end-to-end service
Service levels reflect what users experience across the whole chain, not only each supplier’s component.
Collaboration agreements alongside contracts
Suppliers commit to shared processes, information exchange and joint problem-solving with each other.
Keep strategic control in-house
The client keeps ownership of strategy, architecture and commercial decisions, while integration is run by the integrator.
Integrate tools, not just meetings
Tickets and data flow automatically between supplier tools, so nothing gets lost in e-mail.
Plan exits from day one
Every supplier contract has a documented exit plan, which also supports DORA and NIS2 expectations on third-party risk.
Fact-based supplier reviews
Performance discussions start from shared data, which keeps them constructive and focused on improvement.

AI-powered
Unleash the power of AI
We offer the possibility of using AI throughout this work: ready-to-use AI tools, or a customised version built for your organisation that can run inside your own infrastructure. In service integration, AI analyses tickets across suppliers to find where handovers stall, compares performance with contract terms and drafts supplier review material, so governance meetings start from facts and problems between suppliers are spotted earlier.

FAQ
Frequently asked questions
How long does it take to set up service integration?
Designing the model usually takes six to ten weeks, and onboarding all suppliers often takes several months. We start with the suppliers and services where the problems are greatest.
Do our current suppliers have to agree?
Their cooperation matters, so we involve them early and agree collaboration rules with them. Where contracts lack the necessary terms, we help you add them at renewal.
Can Altechy be both integrator and a supplier?
Yes, and many clients prefer one partner for both. If you want a strictly independent integrator, we can take only the integration role and tell you openly where partners in our network are involved.
Which frameworks do you use?
We build on ITIL and the SIAM body of knowledge, adapted to your size. The goal is a practical model, not extra bureaucracy.
