List the steps you take when conducting research to decide on relevancy of a particular source.

Objectives
These are the questions we are trying to answer. What do we need to know at this point in the design process? What are the knowledge gaps we need to fill?

Hypotheses
These are what we believe we already know. What are our team’s assumptions? What do we think we understand about our users, in terms of both their behaviors and our potential solutions to their needs?

Methods
These address how we plan to fill the gaps in our knowledge. Based on the time and people available, what methods should we select?

Conduct
Gather data through the methods we’ve selected.

Synthesize
Answer our research questions, and prove or disprove our hypotheses. Make sense of the data we’ve gathered to discover what opportunities and implications exist for our design efforts.

Hope this helps for the question you asked.
