In recent years, chatbots have become a growing presence in our everyday lives. Companies have identified various potential use-cases posing opportunities for reducing costs and providing services through automating processes with the help of chatbots. However, although an increasing number of chatbots are developed, user expectations often cannot be met, leading to frequent discontinuation of the bots. Research suggests that for users, one of the main reasons to use a chatbot is to help them increase their productivity. The literature base so far provides little prescriptive knowledge guiding implementation of chatbots specifically for use-cases where productivity is the main purpose. This short paper is the first step within a Design Science Research project to close this gap. We conducted a systematic literature review and gathered chatbot Design Features that were covered in respective publications. In the further course of our project, we intend to implement a prototype chatbot and formulate Design Principles to provide prescriptive knowledge for designing productivity oriented chatbots.
