I was often told by one my first PM/BAs that all requirements should be CAMTU:

Clear, Accurate, Measurable, Trackable, and Unique

We have been struggling with the granularity of our Product Backlog items for months. Our first effort was too small and our current one is too high level. Your examples and the ones from Mountain Goat are more of what I am looking for.

Thanks for the post.
