At one of my jobs, one of my tasks was to take client HR feeds and load them into downstream systems for travel management. On your second day of employment at your company, you should have a profile in our system which was a portal that displayed all travel policies and a profile in whatever booking tool your company used.

We knew who your manager was so approval emails went out automatically. We knew what corporate card was assigned to you, so you never had to deal with that. We knew what preferred vendors your company had agreements with etc

All I was doing was data manipulation and loading on a scheduled or triggered basis. But ultimately it allowed new hires in a new environment to have an easy time booking their trip for mandatory training.

Any time our process failed, you had a traveler stressed out that they wouldn’t be able to book the trip in time or have to outlay money and reimburse later or get stuck at a distant airport.
