  1. Look at the data carefully
    • Do you have all the fields that you will need?
    • Is it a number field? Is it text?
  2. Look for the patterns and trends
  3. Consider the source
    • Are there controls in your data?
    • Are you pulling from an outside source that may not always be available or updated?
  4. Identify the blind spots in your data
    • Think about the questions you can answer using this data.
    • Are there any limitations? If there are, you may need to supplement with additional data.
