Case study / Managed Services
From four supplier queues to one accountable service.
A transformation of a fragmented infrastructure operating model into a single service view, with a maintained configuration baseline, explicit ownership and automation applied to recurring work.

Situation
The context
Infrastructure, endpoint, monitoring and service-desk responsibilities sat across four suppliers. Incidents crossing a boundary routinely stalled because every provider could meet a local target while the end-to-end service still failed.
Each supplier could meet a local target while the end-to-end service still failed.
The first task was not a technology replacement. It was to create a shared view of demand, service relationships and decision ownership that every participating team could operate against.
Intervention
The intervention
Aevis established one service catalogue and escalation path, rebuilt the operating view around dependable service relationships, and introduced runbook automation only after ownership and exception handling were clear.
Service model
Ownership, catalogue and measures
Operational data
CMDB, queues and event context
Automation
High-volume, low-ambiguity work
Transition
Phased handover with acceptance evidence
Delivery path
Change moved at the speed of operational evidence.
The transition was arranged as a sequence of acceptance decisions. Each phase had to leave the service more observable and more clearly owned than it found it.
Weeks 01–03
Baseline
Mapped live services, supplier boundaries, unresolved demand and the measures already being reported.
Decision gateScope and measure baseline acceptedWeeks 04–07
Design
Defined the catalogue, ownership model, escalation path and minimum configuration relationships needed for control.
Decision gateTarget operating model approvedWeeks 08–16
Transition
Moved service groups in waves, ran rehearsals and retained incumbent support until acceptance evidence was complete.

Optimise
Selected automation from stable recurring demand and reviewed exceptions as part of the service-improvement backlog.

Operating shift
The technology mattered. The accountability model changed the service.
The engagement joined process, operational data and tooling around one end-to-end view. These are the practical shifts the case study is designed to make visible.
FromSupplier-specific queues
→ToOne service-facing route
Demand followed the affected service and an explicit owner, even when fulfilment crossed suppliers.
FromInventory-led CMDB
→ToMaintained service context
Only relationships required for triage, change and ownership were prioritised and governed.
FromLocal target reporting
→ToEnd-to-end measures
Measures followed restoration, repeat demand and user impact instead of isolated supplier activity.
FromAutomation by volume
→ToAutomation by confidence
Runbooks were introduced where inputs, ownership and exception handling were stable enough to trust.
