Stick long enough in context-driven testing, and you will hear the term “shallow agreement” one time or another. A shallow agreement happens when we forget to confirm our understanding regarding a user story before starting to work on it, and find out during the Sprint Review – or worse: later – that the functionality did not meet the expectations of our ProductOwner or end-user. Shallow agreement happens when we find out too late that we seemed to agree on something, but really weren’t. We didn’t check our assumptions, and usually both parties end up being disappointed by each other.
Last year, I realized there is also something like shallow disagreements – and I am not sure whether these are worse than shallow agreements.
