We need information all day, every day. Maybe you’ve wanted to go to a restaurant with friends, First, you ask the question, “where is a good restaurant around here?” You may have turned to Siri or Yelp or Google to discover places with good rankings. Once you’d done a few searches, you evaluated your results. Maybe you also refined your question, “Where’s a good Thai restaurant within walking distance?”
Research is a process, not a product.
As in the scenario above, good research involves several steps. You may go back and forth between these steps several times, refining as you go.
