Activity-based scheduling or Location-based scheduling

Please provide some background explanation.
What is "activity based scheduling" and "location based scheduling", and how are they similar or different?
In what way are they more or less equivalent choices?

Project management is essentially about managing Tasks ("activities" if you like). It is not primarily about locations, trades, quantities or anything else. If you are not managing Tasks you are not doing project management, and it won’t work.

Will your survey produce any meaningful results?
Don’t the questions in the survey assume that the person answering the questions knows what these things are, are fully fluent with the software tools and are in a position to make an objective comparison, rather than just clicking on radio buttons.
