For a recent data project, or for an existing data workflow, answer the "Big Three" post-mortem questions.
Based on your current process, what sorts of things do you evaluate to determine success?
What other things should you consider as it relates to data?
What to look for
Using the examples, and your own experience, build (or outline) a brief questionnaire that you could use to gather data prior to a post-mortem.
"An effective postmortem should generate action items. While it shouldn't be a criminal investigation, they're an affirmative process designed to make us all smarter."
--Ken Norten, Partner, GV
Now that you have a questionnaire, your original/current approach, and a working knowledge of what is needed, spend 5 minutes sketching out the changes you would like to make. Present your findings to a neighbor.
