We’ve been working with Tim Williams of Ignition Consulting for 15 years. It’s great, because we learn while we work. Tim is a consultant to many of the largest advertising agencies in the world, helping them with positioning and pricing. Lately we’ve been creating custom illustrations for Propulsion, the Ignition Consulting blog. We receive an advance synopsis of a future blog post and provide him/them with a few concepts, described verbally. Tim chooses one, and we illustrate it. This one is titled Pricing Waterfalls, Cliffs and Fences.
