Dear Lakshmi Natarajan,
BSC is "Balanced score Card"!! Where did you find space for head count in it? Please check - maybe you typed it wrongly!!!!! Or you probably misunderstood the concept of BSC as such!!!!
And Vishnu,
BSC gives you a 360Degree perspective. If you see - its not just focused on one area - but on 4 different perspective which links to the vision. That is how we should be strategically aligned when it comes to Financial, Customer, Internal Business Process, & Learning & Growth perspectives which will help teh company achieve its vision.
Please do search for material on BSC in citehr - there are a lot of good materials on it.
When it comes to HR scorecard - you focus on "linking people, strategy and performance"
Balance score card is the main place where you can define and align the goals of the HR scorecard too or any other departmental scorecards too.
You will also get material on HR score card on citehr.
And pls see attachments I borrowed from citehr! (which is relevant to your question).
Please take an effort to search, understand what is existing, and then put up your question. This is helpful for your learning as well as for other's learning!
