Product Sense: Fixing a Core Pain Point in WhatsApp Group Chats

You are a product manager at Meta working on WhatsApp. Design a product or feature that improves how people communicate in WhatsApp groups. Choose which kinds of groups and which members you are designing for, identify the problem that matters most to them, describe your solution, and explain how you would measure whether it succeeded. ```hint Groups are not all the same A family chat of six people, a sports team's group and a large neighborhood community break down in different ways. Pick one kind of group and walk through a busy day in it from the point of view of the person running it and of a member who has muted it. ``` ### Clarifying Questions - Which groups should we focus on: small friend and family chats, purpose-driven groups such as teams, school classes or residents' groups, large Communities, or groups run by businesses? - Is the scope text only, or also voice notes, calls and shared media in groups? - Is there a launch market in mind, given that group usage is much heavier in places such as India and Brazil than in the US? - Must every part of the design keep end-to-end encryption intact, so that no server can read group messages? ### What a Strong Answer Covers - A chosen group type and member segment, justified by how common and how painful the problem is and by WhatsApp's focus on simple, private messaging - Pain points specific to group dynamics rather than generic chat complaints, with awareness of features WhatsApp already has - Solutions that work under end-to-end encryption, compared and prioritized, with a clear first version - A success metric and guardrails that do not simply reward more messages or more time in the app - Risks such as abuse, privacy and added complexity, and a test plan suited to a feature used by whole groups ### Follow-up Questions - If your feature led people to read fewer group messages, how would you decide whether that is a good or a bad outcome? - How would your design change for an announcement group with a thousand members compared with a family chat? - How could a summary of unread messages work without breaking end-to-end encryption?
