what are good questions for a survey for a dashboard design?

I am a designer, working on a web application, a tool that will be used by multiple users, in collaboration, to create presentations. These users will create presentations for their clients. I now need to design the dashboard for such tool, and need to understand how the users would group and share among themselves the presentation they produce.

I want to send out a survey to possible users. What questions should I include to get really meaningful insights?
I have sent out forms in the past getting vague answers, probably asking the wrong questions.

Thanks
