Summary

That might seem like a lot of steps, but I think when you try this with your own data sources, you will find this process to be intuitive. Prep makes it easy for us to gut check our data to ensure that it matches our expectations at the macro and micro levels. The summary review cards give us a great sense for the distribution of our data, and the detail view lets us focus in on the record level to make sure things line up as expected. I encourage you to try this with your own data. Pick a data source you feel is “good data” and put it through its paces. You might be surprised to find it isn’t as clean as you previously imagined!
