Regarding grating roles to user

Hi,

I have a small query.

In my project we need to assign analytical privileges and also users are only allowed to execute specific models and tables in particular schema.

So my question is  do developers play any role here or HANA security people are authorized to do the same?

Since in my home system I have authorization  of system and I can do the same but in real time are developers allowed to carry out the same?

a.) Assigning analytical privilege to particular user.

b.) assigning roles to particular user.
