Dear Lakshmi Natarajan,
BSC stands for "Balanced Scorecard"!! Where did you find space for headcount in it? Please check - maybe you typed it wrongly!!! Or you probably misunderstood the concept of BSC as such!!!!
And Vishnu,
BSC provides a 360-degree perspective. It is not solely focused on one area but on four different perspectives that are linked to the vision. This strategic alignment is crucial for Financial, Customer, Internal Business Process, and Learning & Growth perspectives, which will help the company achieve its vision.
Please search for material on BSC on citehr - there are many good resources available.
When it comes to the HR scorecard, the focus is on "linking people, strategy, and performance."
The Balanced Scorecard is where you can define and align the goals of the HR scorecard and other departmental scorecards as well.
You will also find material on the HR scorecard on citehr.
And please see the attachments I borrowed from citehr! (relevant to your question).
Please take the time to search, understand what already exists, and then pose your question. This is beneficial for your learning as well as for others' learning!
