Agile means delivering very small increments to users at a frequent pace, allowing them to provide feedback early and often. When done correctly, this eliminates a significant amount of guesswork. However, if the client (or, indeed, your own team or management) does not fully understand the process, things can go spectacularly wrong in many different ways.

We still need to explain what "agile" is. Ask yourself why do we "need" to deliver small increments at frequent pace? Isn't it to be able to react to changes?

I thought I said it. Its main purpose is to eliminate guesswork.
