The service catalogue, by relationship type
| Service | Relationship | The contract's core clause |
|---|---|---|
| Compliance / RG / risk | Mandatory authority with service-grade operations | Response SLAs by severity; the brand obeys outcomes, per the authority structure |
| Payments & treasury | Mandatory infrastructure | Provider onboarding lead times published; approval-rate reads per brand-market cell |
| Data platform & BI | Mandatory core, self-service surface | Freshness SLOs per mart; brands build on the dictionary, never beside it |
| Platform engineering | Shared roadmap | The published queue and prioritisation rule — see brand vs platform |
| CRM operations | Service with brand steering | Brands own strategy and voice inside the gated rule engine; the service owns execution capacity |
| Creative & content ops | Optional service | The one tier where a brand may genuinely go external — and the hatch keeps the internal shop honest |
The contract's anatomy
- Catalogue: what is offered, what is explicitly not, and the request channel — one intake, not five DM threads.
- Response classes: severity tiers with turnarounds, so the compliance deadline and the cosmetic tweak never share a queue position.
- Published performance: the service's own SLA attainment, visible to its customers — the same freshness-on-the-surface honesty as the dashboards.
- The allocation key: stable, usage-weighted where measurable, boring by design.
- The escalation path: documented, to the portfolio owner, with SLA evidence — the hatch that keeps monopoly quality at bay.
Self-service as the scaling strategy
The mature shared service grows by removing itself from loops rather than by adding coordinators: brand-configurable parameters inside guardrails (the configuration matrix pattern generalised), templated request types that execute without human routing, and dashboards that answer the questions tickets used to ask. The heuristic from the FAQ bears repeating as the operating rule: any request type recurring monthly is a self-service feature with a backlog entry.
The two decay modes to watch
The monopoly drift: captive customers, no published SLAs, queue opacity — detected by rising informal workarounds (brands hiring shadow ops, the org-design page's bypass diagnostic). The vendor cosplay: internal invoicing ceremony, negotiation overhead and chargeback disputes consuming more energy than the service delivers — detected when brand leads discuss allocation more than customers. Both decay modes have the same antidote: measure the service like a product (adoption, satisfaction, SLA attainment) and review it in the portfolio rhythm like any other investment.
