Employee Survey for attrition purpose - in which I can understand the main reason for leaving

Dear All, Greetings!
I work as an HR with a Software company which is in the ERP business. I am a fresher and it has been 1 month since I have joined here. During this month, I have seen many people leaving. During their exit interview, I asked them the reason and everyone said they were looking for a better opportunity. So, I want to conduct a survey in which I can understand the main reason for leaving and what they think about the company.
Please guide me as to where should I begin.
Thanks & Regards,
Janice

Dear Janice,
Attrition is a common problem across the industries and there could be company specific reasons. However, before conducting survey, you may do the attrition analysis. Earlier, I have given exhaustive reply about attrition analysis. Check the following link to refer it:

I recommend you doing analysis of the attrition and preparing action plan. Upload the action plan on this forum and some senior like me could suggest corrections.
Thanks,
