Reading a Vendor Claim

Telematics is sold on savings percentages and capability categories. Both need converting into something you can verify.

"Reduces fuel by N percent"

Usually from a fleet with no consumption measurement and substantial unmanaged idling.

Ask: what was the baseline fleet doing before, and does the figure include vehicles where consumption was already managed?

Then measure your own, which gives you the baseline the claim needs and frequently shows less headroom.

"Reads engine data"

A category, not a field list.

Ask: which parameters, on which vehicle model, from the OBD port or the CAN bus?

A vendor who answers the same way for every model is describing a product specification rather than a measurement on your vehicles.

"Predictive maintenance"

Usually means threshold alerts on distance or hours.

Which is useful and is not prediction.

Ask whether it identifies failure patterns from historical data, and if so, from whose data — because a model trained on a different fleet's vehicles may not transfer.

"Real-time tracking"

Means transmitted at an interval.

Ask what the interval is, what happens without network coverage, and whether queued data preserves the original timestamps.

"Fully compliant"

Compliance is a property of your records and configuration.

Ask which obligations they mean, in which jurisdiction, and what the platform retains by default — which is frequently shorter than the compliance requirement.

"Integrates with your systems"

Ask for the interface specification, field by field, not a logo wall.

And ask whether the export is a report or data, because the difference determines whether the maintenance system can consume it.

The general test

Any claim without a named model, a field list, a number or a screen you can break is a statement of intent.

Convert each into a question and ask it in writing, because written answers are more careful and can be attached to the contract.

The carefulness of the answer is itself the information.

Attach the answers to the contract

Which converts a sales claim into a commitment.

Send the questions by email rather than asking in a demonstration.

Ask for the responses to be appended as a schedule.

Written answers are noticeably more careful, and a vendor who will not put the field list in writing has told you something about it.

Connect policy and data

The choices in this note can be compared with inspect the service-desk example. Keep the written purpose in control and enable only the information needed at this boundary.
