Initially do realise FPA (Function Point Analysis) is a estimation technique. IFPUG.org is an international FPA Group which gives you more in detail and in depth, to summarise
fist Break the project into manageable chunks (parts) that you can handle.
Find out the Data Functions and the Transactional Functions, where in Data Functions are any Interface or Logical Files that the user will use to interact with the Application, basically any Internal Logical File or an External Interface File.

This article from Mr.Roger - VP of http://www.qpmg.com/fp-intro.htm is the quick and easiest way to understand.

Then check the User Needs such as the Transactional Need through External Output, External Input and External Inquiries.

Post which a set of Functional Complextity calculated based on the Data Groupins and Data Elements for a Particular Funtion. This data is couted and compated to a complexit Matrix based on the Low Average and High Complexity. This is termed as "Functional Complexity". This output is an Unadjusted Function Point.

Later, these inputs are passed to a set of 14-15 set of recommended questions (check the link at the end of this comment) for a Value Adjustment Factor which will give you a +/- 35% on your Estimate and this is called the Adjusted Function Point.

FPA major advantages have been in checking Scope Creep, any difference in the deliveries, matrice tracking and so on
