The author, an experienced product manager, expresses a strong dislike for slide decks and PowerPoint presentations, arguing that they hinder collaboration, are time-consuming, and impose unnecessary constraints on idea presentation. Instead, the author prefers using virtual whiteboards, product requirements documents (PRDs), and design prototypes, which allow for more dynamic, collaborative, and flexible discussions. Virtual whiteboards offer unlimited possibilities for brainstorming and planning, while PRDs provide a more detailed framework for presenting polished ideas. Design prototypes are favored for visually refined concepts, with AI tools available to assist those lacking design skills. Despite acknowledging some specific use cases for slide decks, such as repetitive information or formal settings, the author believes that these alternatives are generally more effective for product management tasks.
