+    You're about to refactor or add to some existing application code. How confident are you it will work afterwards?
+---
+
+You've been asked to add a new feature to or refactor some existing code.
+
+Assuming you have automated tests already (if not, why not?), before you change the code, you should ask whether they're good enough.
+
+They need to be passing, but do you feel confident the existing functionality will still work after you make your changes?
+
+Do you have all the existing use cases covered?
+
+If so, carry on.
+
+If not, spend some time improving your tests first to get that confidence before making any changes.
