As a product manager, my decision to continue investing in Nest would be based on a thorough analysis of the market, competition, and customer feedback. I would also consider the long-term strategic goals of Google as a company. If the market for smart home devices continues to grow, and Nest is well-positioned to capture a significant share of that market, I would recommend investing in the product. However, if the market is becoming saturated, or if there are other competitors with more advanced technology or better customer support, I would recommend reevaluating the product's positioning and potential for growth. As a Nest PM, I would focus on improving the product's features and user experience, while also working to build strong relationships with customers and partners. This would involve conducting user research to understand their needs and pain points, as well as working with the engineering and design teams to develop new features and improve existing ones. I would also prioritize building out the ecosystem of compatible devices and services, as well as improving the interoperability of Nest with other Google products and services. This would help to create a more seamless experience for users, while also increasing the overall value of the product. Overall, my approach would be to focus on delivering a high-quality product that meets the needs of customers, while also staying competitive in the market and aligned with Google's long-term strategic goals.
