Optimal user experience with a chatbot

Conversational interfaces are gaining ground. The number of websites that are extended with a chatbot is increasing every day. But what actually involves designing the dialogue between client and chatbot? Also on this channel, dialogue design and voice & tone are all-important for an optimal user experience. In a week-long experiment, we developed an Informaat chatbot for making an appointment on our website.

Simplicity and intelligence combined in one tool

Vital in every dialogue is that both partners understand each other quickly and well. That prevents repetition, apology, and annoyance. To realize our chatbot we chose Dialogflow because the rules for the reactions of your chatbot were relatively quick and easy to set up. Moreover, because this tool uses AI to analyze the customer’s intent: for small talk in the greeting and for various indications of time, date, and location during the key phase in the dialogue.

A smart dialogue requires AI

Your chatbot’s dialogue design determines how efficiently and successfully your customer can complete his task. Such a design starts with a diagram of the dialogue’s course. In our case: getting acquainted, customer request, audit questions, options for an appointment, confirmation of the appointment, and completion. We could let our chatbot learn and improve permanently by adding customer input to the decision rules of the chatbot.

The right tone

Which tone best suits your chatbot? That differs per phase in the dialogue. Getting acquainted and completion both require a different tone than more task-oriented phases. Informal language usage and humor fit well with greeting or saying goodbye, but quickly become annoying when your client tries to manage something. Do you want to camouflage restrictions of your chatbot in task-oriented phases? Then use neutral apologies and in-depth questions.

A resilient chatbot

A fully written script of the conversation is a great help to make the dialogue between your chatbot and the client run smoothly. But keep in mind that some customers will push your bot’s boundaries with unexpected questions and reactions, just to put your chatbot to the test. Let your chatbot learn from these questions, but provide striking reactions so that you continue to pleasantly surprise your client at those moments.

Had you asked me in advance if we would be able to develop a chatbot within a week, I would probably have said 'H'm, well…'. The fact that we actually did succeed proves to me the power of the design sprint in combination with a truly T-shaped team.
