I wrote up what I wanted, the team went off and built for two weeks, and what came back wasn't it at all. Reading my own spec now, I can see how they got there. It's the third time this quarter, and the engineers are starting to give me a look before they even open the doc.
More people experience this than they realize.
Your specs are so vague that teams keep building the wrong thing.
If this sounds familiar, the Library can help you find the bigger picture.
