In brief
A group-level service agreement needs to work when a problem crosses subsidiary boundaries. If each operating business meets its own narrow target while the buyer's issue remains unresolved, the service measures are incomplete. Define the end-to-end outcome and then allocate the supporting responsibilities to the businesses that actually control them.

Start with the buyer's service event
Describe a request from submission to accepted closure. Identify intake, allocation, delivery, verification and reporting. Assign an owner to every stage and specify the information that must move between subsidiaries. Avoid measuring only the speed with which the central team acknowledges an email.
Define severity according to the impact on the buyer's operations. Agree when the clock starts, which working windows apply and how pauses are recorded. Any exclusion should have an explanation and evidence, such as a documented access dependency, rather than becoming a general excuse for delay.
Make group coordination measurable
Set expectations for cross-entity escalation, consolidated reporting and correction of inconsistent answers. The group account owner should know which operating manager can act and when the buyer must be involved. Record the authority needed to resolve conflicts over resources or responsibility.
For example, one subsidiary may identify a defect while another must repair it. The buyer needs a single view of the open issue, including the current owner and next action. Closing the inspection ticket while leaving the repair unassigned would create a misleading picture of performance.
Keep workstream evidence available
Use a common issue identifier while retaining subsidiary-level records. Agree what proves completion for each service and who can accept it. A central dashboard should link to this evidence so the buyer can investigate a missed target without requesting a separate report from every business.
Review exclusions and reopened issues as well as headline compliance. Repeated reassignment between subsidiaries may reveal a structural problem even when each handoff occurs within its individual target. Ask for corrective action that changes the interface, not only a promise to communicate better.
Test the agreement before full mobilisation
Walk through an ordinary request and a cross-workstream incident with the proposed teams. Resolve unclear ownership and inconsistent timing assumptions before launch. Have contractual remedies reviewed for the particular agreement and avoid assuming that a service credit alone compensates for an operational failure. The strongest service levels combine clear evidence, realistic responsibilities and a workable route to correction.
