How to best name enterprise tools or portals?

If you have worked within a large organisation you would have most probably operated in highly siloed environments with a lot of legacy systems and third party software. I have worked in a number of big organisation as an information architect and I am struck by one practice in particular, namely how departments create names for their internal products, tools or portals of which there is of course plenty!

There is of course the excessive use of acronyms to describe software but there are also product names that fail at describing what any given piece of software does. As an example; a simple exercise intended to get access / permission to use a portal or a tool becomes extremely difficult without knowing exactly the name of the product or tool which is a big findability issue. So my question is :

  1. Is there any resource or guidance for naming enterprise tools or portals?

  2. What advice / guidance best practices would you suggest?
