Information creation is a process.

Throughout the process, it is helpful to reflect on what you have found and what you have learned so far. At this point, ask yourself some questions:
Do you need more information?
Would it be helpful to include some statistics to make your argument stronger?
Perhaps a video could help illustrate your point?
Basically, what information do you need to help make your case?
This is also a good time to consider revising and polishing your work.
