I had intoduced the Buddy programme a while back in my organisation. i see a very good response of this programme and it had helped the new joinees alot.
All you will have to do is
Motivate your employees to be the Buddy,
Tell them the objective of the programme
Ask them ideas to make if better
give them a sense of ownership of the entire programme
Also what makes them feel happy and motivated is share the feedback of the new joinee( positive ones :) ) with the buddy
And then dont forget to reward could be a small gift as an appreciation
i have attached the feedback forms, you could use it it helps :)
Thanks
