Working with a new customer I try to find out the company ontology (internal language). They use specific words that could mean different things in other context, but internally they have specific phrases and expressions that all employees know. This is something that has evolved over time, but is (unfortunately for me) not written down. How do I document this ontology, and how do I make sure that I don’t miss anything?
So far I’ve interviewed a few of the longest employed staff, but I’m not confident I’ve made a complete ontology.
