Could it be that your description of Zuora as a simple USP/single driving change business is actually a testament to the simple way they tell their story? I'm the author of the post, and every business I consult with is, as you say, "complex...addressing multiple trends or with multiple layers of innovation..." That hasn't stopped any of them from crafting a similarly simple story -- starting with a single change. Usually that means either (a) focusing on the most important one; or (b) naming a change that subsumes many of the others. Getting leadership teams to align around one change isn't easy, but I'm getting better at it :)
