Adhering to a naming convention for platform customisations is in general a good idea. This helps enforce consistency across different teams, and over time. It also serves to clearly separate the newly created configuration items from modifications made to out-of-the-box elements.
Naming conventions can take many shapes, but some of the most common are enforcing the use of a given prefix / suffix for newly created Configuration Elements (CEs), and limiting the character sets which can be used to name them. This can be especially important for multinational teams working across different locations.
