But keep in mind that customers have a lot of work to do. They need to figure out what provides the most value, set the appropriate priorities for the work, identify all the details that developers will ask about, and fit in time for customer reviews and examples. They need to do all this while staying one step ahead of the programmers, who—especially on Delivering teams—are right behind them, crunching through work like a freight train. It’s a big job. Don’t underestimate it.
