How is it that you can have excellent suppliers and still receive a poor service?
It sounds strange until you picture a relay race. Each runner can be fast, trained, and committed, perhaps the best in the world, but the team loses if the baton handoff is messy. In multi-provider IT, the same thing happens: the biggest failures often occur between providers, not inside them. We’re not looking for a weak link, rather the integrity of the whole chain.
In this blog, we introduce the ‘dropped baton’ concept, and look at how service integration and management (SIAM) can help to fix it and reduce accumulating interface debt. Many IT organizations are familiar with the ‘watermelon effect’ where services are reported as green but are actually operating in the red. The dropped baton effect evolves this concept for the complex world of multi-provider delivery.
When the baton drops, everyone pays
Consider the scenario shown in this image. All providers are fulfilling their contractual requirements and target, but the customer is still unable to pay an invoice. The problem is happening at the integration level, not the component services. In a multi-sourced ecosystem, services flow across internal teams, outsourced partners, and specialist vendors. Each party brings capability, but without a unifying operating model, you end up with friction at the seams:
- Miscommunication at transition points: because processes and terminology don’t align
- Fragmented accountability: when incidents span multiple providers, leading to delays and finger-pointing
- Inconsistent service quality: because each provider optimizes their segment rather than the end-to-end experience
- Blurred ownership: that turns restoration into a debate instead of a coordinated response
Eventually, this leads to downtime, higher risk exposure, escalating cost, and frustrated employees and customers, despite each supplier proving they met their own contract measures.
Scopism research reflects this challenge, with more than 82% of organizations wanting to have better performance from their existing providers.
SIAM adds the team captain: end-to-end accountability
SIAM is a management methodology used to create value in ecosystems where multiple service providers deliver services. It introduces the concept of the service integrator: accountable for the end-to-end delivery of services through governance, coordination, assurance, and integration across the ecosystem. Think of the service integrator as the team captain in the relay:
- Ensuring every runner knows their role
- Standardising how the baton is handed over
- Aligning performance measures to the team’s finish line
- Spotting issues early and removing blockers
- Making sure the whole service “race” stays on track, regardless of who runs which leg
SIAM makes integration intentional, so the service behaves like one coherent system rather than a set of disconnected delivery segments.
Scopism’s point of view: the growth of interface debt
To understand why multi-provider issues get worse over time, it helps to name the hidden mechanism: interface debt. You may have heard the phrase interface deb used in product and UX circles to describe the accumulated cost of a clunky or inconsistent user interface. This idea is even more powerful when applied to multi-provider service ecosystems.
Interface debt is “the accumulated cost of poorly designed, poorly governed, or poorly executed interfaces between parties in a service ecosystem, across technology, operating model and organizational boundaries. It includes technical interfaces (tools, integrations, data models, workflows) and contractual/operational interfaces (handoffs, responsibilities, KPIs, escalation paths).”
It’s similar to technical debt: shortcuts can feel efficient in the moment (“we’ll reconcile data manually”, “we’ll align processes later”, “we’ll fix the ownership model after transition”), but the interest compounds. Over time, interface debt shows up as:
- Work sitting in queues because handoffs aren’t clear
- Manual reporting because tools and data don’t align
- Repeated incident ping-pong between providers
- Change failures caused by unmanaged dependencies
- Blame culture that destroys collaboration and speed
SIAM is, fundamentally, a strategy for preventing and paying down interface debt. It makes interfaces visible, assigns ownership, and provides end-to-end governance.
What SIAM changes in practice
Effective SIAM shifts the ecosystem in four important ways:
- Accountability becomes end-to-end: roles and responsibilities are clarified across the service chain, so issues don’t fall into the gaps.
- Integration is designed into the operating model: SIAM creates a structured way to define governance, scope, processes, and measures for the integrated service across all providers.
- Commercial alignment supports collaboration: contracts and targets can be structured to encourage providers to work together and maintain “loose coupling”. This enables change without destabilizing the ecosystem.
- Measurement reflects the customer experience: rather than relying on siloed supplier reporting, SIAM enables end-to-end visibility and insight. This is impossible to do well when tooling and data remain fragmented.
Are you dropping the baton?
If you’re wondering whether you have a dropped baton problem and rising interface debt, look for these signals:
- Incidents bounce between providers while ownership is debated
- End-to-end reporting is manual, slow, or disputed
- Changes cause surprises because dependencies aren’t visible or governed
If you want to reduce risk, improve performance, and create a service ecosystem that works as one team, you need to start with the integrations to win the race.
