Imagine you are a Product Manager tasked with designing a novel restaurant experience specifically for puppies. Consider the unique needs, behaviors, and preferences of puppies, as well as the concerns of their owners. Your design should encompass the physical space, menu, service model, and any technological integrations. How would you approach defining the target audience, identifying key features, and measuring success? What potential challenges would you anticipate and how would you address them? Be prepared to articulate your product vision, user flows, and key considerations for this unique venture.
