“I never saw it coming.” That’s what I remember thinking when it was all said and done. I remember having a lively debate about the topic. Then I remember frustration and, before I knew it, it was over. My client had just asked me to do them a “favor.” Only it wasn’t a favor — it was a significant scope change. I put up a rigorous argument for why they couldn’t change the scope, but as they got more frustrated with me for not simply acquiescing, they finally said, “I’m the client — do it.” That’s when I realized I’d made a terrible mistake, but I was going to be ready for it next time.
