When @peter and I conduct Agile trainings, people tend to get hung up on the nuances of these. And that’s okay – it still provides a space for a healthy discussion. So I thought I’d throw one out here for Friday kicks!
“Working software is the primary measure of progress” is one of the 12 Agile Principles. Is it though? I agree with this principle, but also I’d say TESTABLE software is the primary measure of progress. It is then whether or not we know if it meets the acceptance criteria or expectations of the user.
