Product Sense: Improving the Everyday Water Bottle for a Chosen User Segment

As a product manager, you are asked to design an improved water bottle. Decide who it should be better for, explain what is wrong with today's bottles for those people, propose a design, and say how you would know it succeeded. ```hint Better for whom A commuter, a trail runner, a parent packing a child's school bag and a frequent traveler each have a different complaint about the same bottle. Pick one group before you pick features. ``` ### Clarifying Questions - Do we mean a reusable bottle someone carries around, or single-use bottled water sold in stores? - Are we a hardware maker that can design and manufacture the bottle ourselves, or would the bottle be a companion to an app or service? - What is the goal: winning share in a crowded market, building a premium product, or a health outcome such as people drinking more water? - Is there a target price or cost ceiling, and is adding electronics acceptable? ### What a Strong Answer Covers - A stated goal and a deliberately chosen user segment, with a reason for the choice. - Concrete pain points across the bottle's daily life, such as filling, carrying, drinking, temperature and cleaning, ranked by frequency and severity. - Several distinct solutions prioritized by impact, cost and fit with the goal, including at least one simple, non-electronic option. - Physical-product realities: unit cost, weight, washability, durability, charging and safety. - Success metrics and a way to validate the design before committing to manufacturing. ### Follow-up Questions - Your top idea adds electronics to the bottle. How do you handle washing, charging and the higher price? - How would you test demand and the design before paying for a production run? - How would the design change if the target user were young children?
