How to define user's organization levels for Intranet applications

Hi all,

My company wants to use Matomo into our Intranet. I’m a newbie on Matomo and web analytics in general and I’m searching the best way to materialize the company organization levels into Matomo. Do I use custom variables or dimension variables to indicate these levels ? Another way ? Location variables are too general, maybe if we could extend these…

What are your recommandations ?

Thanks for your help
