In the previous chapter, we talked at length about the evolution of UI and, more specifically, conversational UI. We discussed the technical stacks of conversational solutions, as well as the differences between voice and chat solutions. We focused on some of the challenges of evolving those solutions and explored some ideas on how to do this.

The next few chapters will provide tips and ideas on how to build a successful conversational UI for both chat and voice applications. However, before we start analyzing the requirements for a conversational application, I would like to give some thought to conversational UI and how building it wrongly can make it bad.
