Permission Issue on HP-UX

Good day guys,
I am very new in UNIX and am trying to install an application which uses an application ID that requires administrative privileges (Full control). In most cases, we use SUDO to grant access to this ID however the customer insisted NOT to use SUDO and Root ID is not to be used to install the application. Is there any available method to get this ID full access like the root access without going through SUDO?

Please advice.

Thanks.

IMHO, unless the customer can give you really good reason for not using SUDO, Iwould go ahead with it or at least use su -...
Did you try to explain (even id not true - but get it done quickly...) root account can only be used at the console and that is computer room where access is limited to issues solving, and console is not GUI... ?
