How to Become a Business Process Analyst?

I am fresh graduate of Computer Science and want to become a Business Process Analyst.

What skills do I need and what experience I should look out to gain ?

Are there any classifications which can help me in this endeavor. I have a only fade idea of what a Business Process Analyst does i.e. of mapping business processes and analyzing which need improvement or how they can integrated into a software.

Is is this right? Advice from experienced people or those who are already or trying to be in the same field will be highly appreciated.
