Fundamental use of the Oracle aset tracking.

Sorry I am a newbie to asset tracking and so these fundamental questions.

The Oracle user guide says that "With Oracle Asset Tracking, you can give users access to tracking information without

allowing them access to sensitive processes related to assets and purchasing".

Having worked on multiple oracle applications including Financials and Manufacturing I am thinking as follows.

With somuch of security built in by users and responsibilities,cant we hide the sensitive processes and programs and only provide the readonly forms for the users to track the information. Do we need a separate module in tracking the asset item instances?
