This we learn from a recent posting at herdingcats:
"We must be crystal clear here. Requirements may emerge, but the needed capabilities at the needed time are a critical success factor for any project, no matter the domain. As Yogi reminds us. If you don't know where you're going, you might not get there."
Of course, the posting goes on to cite some sources, among which I find myself, for which I am gratified to be included:

Young, Artech House, 2004[2] Requirements Engineering: A Good Practice Guide, Ian Sommerville and Pete Sawyer, John Wiley & Sons, 1997[3] Succeeding with Agile: Software Development Using Scrum, Mike Cohn Addison-Wesley, 2010.[4] Project Management the Agile Way: Making it Work in the Enterprise, 2nd Edition, John C.
