SAP CRM Implementation Process

Hi Guy's,

I am kind of new to SAP CRM... I am in the process of finding as much information as possible regarding SAP CRM. I have a general question (show below) regarding CRM Implementation... I am hoping to get an answer from you....

Q: If any Company chooses to implement SAP CRM in 2 or more phases.... then which functionalities (Ex: in Marketing, Sales and CIC) the company would implement in the 1st phase and what are the other functionalities he would like to implement in the next phases?

Let me know if the question is not clear enough....

I really appreciate, if you could explain in detail.....

Thanks in advance...
