Writing an SLA for scheduled transport services

In brief

Scheduled transport needs clearly defined arrival and completion events. A vague punctuality promise can create disagreement over whether a vehicle was ready to board, merely nearby, or at the correct entrance.

What to do

Define the pickup location and the event used to measure arrival.
Separate supplier delays from passenger, loading, or access delays.
Agree escalation, replacement, and incident-reporting responsibilities.

Define the measurement and the exception

For each service measure, write the start event, stop event, data source, reporting owner, and agreed exclusions. Choose a target with the supplier that reflects the operating need and available evidence; the target is a commercial proposal, not an industry-wide standard. Explain how disputed records will be resolved and when a recurring problem must be escalated.

Run the measure through one ordinary event and one exception before signing. If the two parties calculate different results from the same facts, refine the definition. A short set of observable commitments is easier to manage than a long list that nobody can verify.

Illustrative buying situation

Consider this hypothetical example.

A vehicle reaches the site gate on time but cannot reach the boarding point. The buyer and supplier disagree about whether the trip was late. Define the measurement event using the actual service requirement and distinguish access delays from supplier arrival delays. Test the wording against this scenario before the next reporting period. A measurable standard needs a shared event and evidence source, not only an agreed number of minutes.

Your next decision

Review service against consistent trip records and investigate repeated causes of disruption.
