Did we find the research that we needed? 
Did we find enough? 
Is our evidence credible? 

Does it support or challenge our hypothesis? 
Do we have any information that challenges our ideas? 
Should we include it as rebuttal information that we can counter? 
How can we counter those challenges effectively? 

We use sources to back up our ideas and claims rather than letting the sources do the claiming.
Have we struck a balance between us and the sources?
