advice for surveys on software tool and business administration



Dear forum participants:

I am designing a survey for a a simple software tool. The objective is that I need to assess its effectiveness, user friendliness and general feedback from the users.

At the same time, I need to design a survey focusing on the scalability of a business, and its market potential; and I have no idea which financial indicators aside from profits I need to consider.

Has anyone worked in these fields before and could advice me of an existing survey, or literature that can help me?

many thanks
