Product improvement case: making WhatsApp's in-app search more useful

You are a product manager asked how you would improve search in WhatsApp. No other context is given, so you set your own assumptions. Explain what the improvement should achieve, whose searches you would focus on, which changes you would make and in what order, and how you would know they worked. ```hint Separate the search intents List the different things people go looking for in WhatsApp, then pick the intent where today's search most often leaves your chosen users without an answer. ``` ### Clarifying Questions - Does "search" mean the search bar above the chat list, search inside a single chat, or both, and does it cover photos, documents, links and voice notes as well as message text? - Which users matter most: people in many busy groups, people who coordinate work or a small business in WhatsApp, or people looking for new groups, channels or businesses? - Should the design assume message content stays end-to-end encrypted, so any search over messages has to run on the phone itself? - Is the aim retention and daily use, or a business goal such as helping people find businesses? ### What a Strong Answer Covers - A stated goal for search and why it matters to WhatsApp - The distinct reasons people search, with one user segment chosen and the reason for the choice - Pain points in that segment's search journey, ranked by frequency and severity - Solutions prioritized with explicit criteria, including privacy and how well they run on lower-end phones - A measure of search success, with guardrails ### Follow-up Questions - How would you measure whether a search succeeded while respecting the privacy of what people search for? - How would your plan change for markets where most people use inexpensive Android phones with little free storage? - If leadership asked you to add discovery of public groups or businesses to search, how would you handle spam and safety?
