When do small frictions reveal structural problems? Is there a fragmentation tax and a hidden cost of disjointed orchestration in the supply chain? Dima Karlinsky (pictured, below), Chief Business Officer at Unilog SC, explains.
There’s a moment in every critical Service Level Agreement (SLA) parts network where something small reveals something structural. A part misses a four-hour SLA not because it wasn’t in the country, but because no one was quite sure who owned the handoff. A shipment sits at customs while teams debate who the Importer of Record should have been. Two regions quietly increase safety stock on the same SKU ‘just to be safe’. An escalation call includes five organisations and no single line of accountability.
Nothing catastrophic. Just friction. Individually, these moments look operational. Together, they are architectural.
How Fragmentation Creeps In
Global service parts networks rarely begin fragmented. They evolve that way. A regional specialist is added to close a performance gap. A repair partner shortens turnaround time. A trade advisor manages compliance complexity. A 4PL layer is introduced to connect it all.
Each decision is rational. Often necessary. But over time, orchestration becomes layered rather than unified. In high-availability environments such as cybersecurity infrastructure, optical networks, data centres and medical systems, that layering begins to create hidden costs.
Where the Costs Appear
Fragmentation first shows up in inventory. When regions operate with partial visibility of each other’s positioning, they hedge. The US carries stock to protect its SLA exposure. Europe does the same. APAC does the same again. Individually, the decisions make sense. At the network level, they inflate safety stock, tying up working capital in duplicated buffers that exist purely to compensate for uncertainty.
It also distorts performance reporting. One provider starts the SLA clock at dispatch, another at delivery attempt. Reverse logistics is measured separately from forward fulfilment. Dashboards appear aligned until volatility hits, and suddenly, no one can reconcile where the delay actually occurred.
Trade governance becomes another pressure point. In global service networks, customs clearance is not a back-office activity; it is part of the uptime system. When Importer of Record responsibilities shift between providers or vary by region, ambiguity creeps in. A customs hold under a four-hour SLA is no longer just a compliance issue. It becomes a service outage.
Reverse flows create their own consequences. Repairable assets moving across borders without unified visibility become what operators quietly call ‘dark inventory’. The asset exists somewhere in the network but cannot be deployed when it is needed. The forward network compensates the only way it can, by carrying more stock.
When problems escalate, fragmentation becomes most visible. In multi-provider models, root cause rarely sits neatly in one organisation. Escalations move sideways before they move forward. Accountability becomes sequential rather than simultaneous. Under stable conditions, the system absorbs that latency. Under disruption, including tariffs, geopolitical shifts and capacity shocks, the latency becomes exposure.
The Fragmentation Tax
Multi-provider strategies are often adopted to reduce concentration risk. That logic makes sense.
But in high-SLA service environments, fragmentation introduces a different risk: coordination failure.
When orchestration is disjointed, the network begins paying what might be called a fragmentation tax, in duplicated inventory, premium freight, delayed recovery times and the growing overhead required simply to keep the system aligned.
The tax rarely appears on a single P&L line. It accumulates quietly across buffers, expediting, working capital and management attention.
A Different Question
As global service networks expand and trade regimes tighten, leaders are starting to ask different questions. Not ‘Are our providers performing?’ but ‘Is our orchestration structurally unified?’, because in high-availability service networks, architecture is no longer just an operational choice. It is a resilience strategy. Every network pays for its design. The only question is whether the cost is visible.
