@fbecart I always encourage teams to pay attention to repetition. It's a hint as to what the design or the process really needs to be.

When I illustrate this, I actually do use testing as the example. I get them to REPL test some code as they're writing it, and keep a count of the number of times they perform the same test. When it reaches 3 (The Rule of Three), I ask them to automate that test in a main() function.
