This talk of Dr. Russell Ackoff gives great examples of system thinking.

comment Should I re-test fix at system level when the issue is at unit level?
But you may build your inference model based on observation, can't you? If you observe that removing a fault X in the component Y removed the failure Z in conditions W then you may suspect there's cause-effect relationship between those elements. As one learns what are the relationships between unit failures and system failures, his or her mental model of the system will become more realistic and thus credible.

I agree failures at unit and end-to-end levels are two different failures.

I agree with your points! However, most of your points relate to faulty component, incompetent developer, etc. while there might be reasons also on tester’s side, e.g. that the tester isolated the bug incorrectly, and there is no cause-effect relationship between the cause I found and defect that occurred. A particular case of that would be that there were multiple causes of the defect in different components, and we fixed only one of those causes.

Joe, those are great questions but I think I may lack instruments to answer them. My feeling is that system thinking is one of such instruments to understand how system parts relate to each other. What would be other useful instruments here?

comment Reviewing unit tests before implementation
+1 for cycles. TDD is done in cycles: unit tests are very close to the code (and so solution and architecture) that is evolving. So it would make no sense to have unit tests written once and freeze them forever. It would however, make more sense to agree on some high-level acceptance tests in advance.
