Dear Mr. Siva,
First of all, prepare an induction format if it is not available in your organization. In general, all the new incumbents will approach HR. The HR will provide all the relevant forms like Joining report, PF, ESI, nomination form, confidentiality agreement, etc., and obtain all the testimonials, copies of certificates, address proof, PAN No., Bank account no., passport size photographs, etc., from the new employee. Prepare a welcome note and if you have mail IDs for all HODs, then forward the same to all the HODs and also display one hard copy on the notice board.
Take the employee to his HOD and introduce. If it is a big organization and the employee is in a senior position, then call for a meeting of HODs and introduce. If not, introduce to all HODs. Let him go through all the HR systems, processes, policies, formats related to the employee. Also, communicate with him about in & out procedures, dos & don'ts, etc., and then let the guy go to the concerned department. You (HR) are responsible for creating a mail ID, providing ID cards, Business cards, Desktop/Laptop, etc., as per eligibility.
I opine that you should prepare an induction schedule and checklist.
If you need anything further, please forward an email to my ID [Login to view].
These are the basic things that you have to quickly acquire.
