Hi Buddy,
I would definitely agree with what Ajmal has to say, that it's going to be quite a lengthy process, but I'm trying to answer your question in a few lines. It's not that I know better, I'm just putting in my effort. If it helps you, well and good. If not, maybe you can develop on it with help from other knowledgeable members of CHR.
Well, see if you can lay hands on this book by K Aswathappa titled "Human Resource and Personnel Management." Page 15 of this book has a graphical representation. Go through that; I feel this answers your question. I don't have a soft copy of the same; if I did, I would've posted it right away. Maybe once you read through that, you can seek help from senior members on CHR, and they might be able to assist you even better.
Regards, Manju Ananth Bharadwaj
