I suppose you are the one in the HR department. Just see the main requirements of your company. In my view, you cannot start from Performance Management / T&D. Obviously, it will be required but later on. You can start from the personnel file, then its MIS. Design the leave policy, Time Office, and design the holiday list for 2013 as this year is about to end. Establish policies on Recruitment, Payroll, etc. Later on, you can create a Policy Handbook for the company. Also, try to create MIS for almost everything. It will make your work easier later on. Based on the situation and time, you will have to adopt what you need to do. All the very best!
