Understanding the technology behind conversational assistants is crucial for conversation designers, as it allows them to design effective conversations within the scope of what's possible today and anticipate future possibilities. The workflow typically involves defining a problem, setting objectives, creating personas, writing sample dialogs, testing with Wizard of Oz testing, prototyping early happy paths, adding copywriting, conducting unguided user testing, and passing off design to developers. Conversation designers often use tools like spreadsheets, word documents, and flowcharts in tandem to provide a comprehensive view of the conversation. To build a portfolio as a conversation designer, it's essential to start with everyday interactions and create designs that reflect real-world conversations.
