Generally in drupal modules are executed in as per the weight in the specified by the system table. 

If two module has the same weight then modules are executed alphabetical order based on the name of module. 

 
During working on one of my project, I was working with workflow module. 

New version of workflow module adds Target State radio buttons on node form. I wanted to move these radio buttons to vertical tabs in node creation form. 

I created a module for the form_alter function. I named my module as my_module.module.

As Drupal is hailed as good CMS if you want to alter any existing thing.
The hook architecture of drupal makes it possible to alter any thing.
 
You can also add custom acess callback for any menu item.
To add custom menu access callback you can user hook_menu_alter() function.
 
As per the documentation this hook Alter the data being saved to the {menu_router} table after hook_menu is invoked.
 
This hook is invoked by menu_router_build(). The menu definitions are passed in by reference.
Each element of the $items array is one item returned by a module from hook_menu.

This function fetches the role from the role name, and it will return a fully-loaded role object if a role with the given name exists, or FALSE otherwise.
 
I used this function to load the role object which i passed as string in $role_name.
 
Now function  user_multiple_role_edit() will allow to add roles to the users.

Recently working with administrator account i encountered a problem. When i visit the profile of other user, i was not able to see the email id of the registered user.
