Not if you call the understanding and design processes a "design sprint"!

As someone else said, the individual phases can be huge, which is why in large projects the first step is often to break down large business needs into more manageable chunks, each of which can be worked on seperately, either linelarly or by multiple teams. In a healthy process as the work progresses it is used to reevaluate previous decisons & designs. So basically agile.
