The product backlog items are detailed appropriately, as illustrated in Figure 3.1. Higher-priority items are described in more detail than lower-priority ones. “The lower the priority, the less detail, until you can barely make out the backlog item,” write Schwaber and Beedle (2002, 33). Following this guideline keeps the backlog concise and ensures that the items likely to be implemented in the next sprint are workable. As a consequence, requirements are discovered, decomposed, and refined throughout the entire project.

Spending too much time understanding the detail of future requirements is a waste of energy. The world tomorrow is not the same as the world today.

Focus on what you will deliver next. I like the statement "until you can barely make out the backlog item".
