Hi Buddy,
Would definitely agree by what Ajmal has to say, that it's going to be quite a lengthy process, but trying to answer your question in a few lines.. It's not that i know better, just putting my effort.
If it helps you well and good if not may be 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. Title HUMAN RESOURCE AND PERSONNEL MANAGEMENT. Page 15 of this book has a graphical representation.
Go through that, this i feel, answers your question. I don't have a soft copy of the same, if not would've posted it right away. Maybe once you read through that you can take help from senior members on CHR and they might be able to help you even better...
Regards
