The dominant idea in corporate travel technology for the last decade has been self service. Give travellers a booking tool, encode the policy into the workflow, and let the system enforce compliance without human intervention. The logic is sound and the results have been mixed.
What self service actually shifted
Booking tools did not remove the work. They moved it from a specialist to the traveller, who is slower at it, less familiar with the policy, and more expensive per hour. A senior manager spending twenty minutes comparing rates is a worse allocation of time than a service manager spending five.
Exception handling is where the model breaks down completely. Platforms are efficient at the common case and poor at the unusual one, and business travel is full of unusual cases: a delayed flight, a property that cannot honour a reservation, a change of plan mid trip.
The case for a named person
A dedicated service manager holds context that no system captures: which travellers dislike which properties, which hotels reliably honour upgrade commitments, which cities need booking further ahead during conference season.
The point is not that technology has no role. Dashboards, consolidated invoicing and compliance reporting are all better done by software. The point is that the booking relationship itself benefits from a person who is accountable for the outcome.
