You're the PM of Apple Watch, how would you design it?

This question is asking you to think about the function, interface, user experience, and overall design for a real-world, current product. They want to see how you would approach the strategic decision-making inherent in a Product Manager's role. The way to tackle this question includes understanding your target users, identifying their needs, generating ideas to meet these needs, selecting the best ideas, prototyping, and testing.

Key considerations would include:

• Understanding target users: Who are the end-users and what do they value in a smartwatch
• Identifying their needs: What problems are you solving for these users?
• Ideas generation: What features would you include to solve these problems?
• Selection: Out of those possible features, which will be the most beneficial?
• Prototyping: How will this product physically look, how will the interface work, etc.?
• Testing: How would you validate your decisions with actual users?

By considering the target customers of the Apple Watch, which broadly, are individuals who can afford Apple products and seek high-end smartwatches to keep track of their wellness, communication, and productivity needs. Hence, building on the existing Apple ecosystem will be integral to the design.

The current needs of these users are easy access to health data, a customizable interface, seamless connectivity, and a fashionable accessory. To address these, I would add a feature that allows users to customize the health metrics they see on their homepage. I would also increase the watch's screen size without impacting its overall size to display more content conveniently.

Based on user reviews, a common issue raised is the watch's battery life. Enhancing the battery efficiency would be crucial in the watch's new design.

Lastly, the Apple Watch is well-known for possessing a fashionable element. I would propose partnering with fashion brands to offer limited-edition straps, along with allowing personalized watch faces, enhancing the fashionable element even more.

For testing, prototypes would be given to a selected user group to gather feedback and make necessary refinements before the official launch.

As a Product Manager of the Apple Watch, I would assume that we are targeting affluent, tech-savvy consumers who are health-conscious and appreciate seamless technology integration.

Based on these user requirements, an important function would be to ensure that it integrates smoothly with the other Apple products for a seamless user experience. Another key aspect would be focusing on functionality that promotes users' health. Adding more advanced health tracking aspects like blood pressure monitoring, glucose level testing, and even stress levels monitoring could be beneficial.

From a design perspective, I would ensure the watch maintains Apple's signature minimalist and sleek design but perhaps introduce more customization options – such as interchangeable watch faces and more strap choices.

We could also enhance accessibility for visually impaired and elderly users. Increasing the font size, simplifying commands, and incorporating voice navigation would make the product more inclusive.

Then, testing through user interviews and prototypes would validate the usefulness of the new features and improvements. This feedback would be instrumental to iterate on the design before finalizing.
